A Tributary is a smaller stream that is a constituent part of a larger River system — a "part : larger whole" relation. Applying this, a State is a constituent political unit of a larger Country. "Village" reverses the direction (a village is smaller than a state), and "Continent" is too remote a whole. Answer: Country.

The relation between the two triples is the alphabetical opposite — each pair of corresponding letters sums to 27 (A↔Z, B↔Y, …). Check: W(23)+D(4)=27, U(21)+F(6)=27, S(19)+H(8)=27. Applying the same rule to MKI: \(27-13=14 \to N,\ 27-11=16 \to P,\ 27-9=18 \to R\) So MKI corresponds to NPR.

The relation in the first pair is the negative reciprocal: numerator and denominator are swapped and the sign is flipped. Check: \(-\dfrac{3}{7} \to \dfrac{7}{3}\) (swap + change sign). Applying the same to \(\dfrac{9}{2}\): swap to \(\dfrac{2}{9}\) and flip sign, giving \(-\dfrac{2}{9}\).

Nephew, Grandson and Great grandfather are all blood relations (consanguineous), tied through lineage. Mother-in-Law, however, is a relation established by marriage (affinal). Hence it is the odd one out.

GHI, XYZ and CDE are three consecutive letters in forward alphabetical order. VUT is three consecutive letters in backward order (T, U, V reversed). Hence VUT is the odd one out.

Among 43, 22, 13 and 41, three numbers (43, 13, 41) are odd (not divisible by 2). Only 22 is even, making it the odd one out.

Count the letters in each word: Shy (3), Food (4), Plate (5), Recess (6). Each successive word adds one letter. The next term must have 7 letters. Among the options, only Monsoon (M-O-N-S-O-O-N) has 7 letters.

Each term has six characters — one X and five Is — and the X shifts one place to the right at every step: positions 1, 2, 3, 4, 5 in the given terms. The next term must place X at position 6, giving IIIIIX.

The series consists of squares of consecutive integers: \(7^2=49,\ 8^2=64,\ ?\ ,\ 10^2=100,\ 11^2=121\) The missing term is \(9^2=81\).

Step 1 — Count days from 18 May to 19 Aug: Remaining May: \(31-18=13\); June: 30; July: 31; August: 19. \(13+30+31+19=93\) days. Step 2 — Odd days: \(93\div 7\) leaves remainder 2. Step 3 — Shift day: Thursday + 2 days = Saturday.

Possible subset sums of {30, 40, 50, 100} (each box used at most once): 30, 40, 50, 70, 80, 90, 100, 120, 130, 140, 150, 170, 180, 190, 220. Checking options — 140 = 40+100, 180 = 30+50+100, 190 = 40+50+100, all achievable. 160 cannot be formed by any subset.

Letters available in ECCENTRICITY: C(3), E(2), N(1), T(2), R(1), I(2), Y(1). NIECE, TRINITY and RETICENT use only these letters within the available counts. CREATE requires the letter A, which does not appear in ECCENTRICITY, so it cannot be formed.

Each letter of ETHANOL is shifted forward by 3 positions: E→H, T→W, H→K, A→D, N→Q, O→R, L→O. Applying the same \(+3\) shift to MIX: M→P, I→L, X→A (wrap-around 24+3=27→1). Code = PLA.

Apply the substitutions to \(24\times 6 - 8 + 2\): \(\times\to\div\), \(-\to+\), \(+\to\times\), giving \(24\div 6 + 8\times 2\). By BODMAS: \(24\div 6=4\) and \(8\times 2=16\), so the value is \(4+16=20\).

The pattern is (sum of digits of first number) + (sum of digits of second number). Check: \(10\$25:(1+0)+(2+5)=1+7=8\); \(12\$25:(1+2)+(2+5)=3+7=10\). Apply to \(14\$53:(1+4)+(5+3)=5+8=13\).

The pattern followed is: (45 + 12) = 57 (11 + 0) = 11 So, (1 + 1) = 2 Hence, the answer is 2.

Step 1 — Track X: Take the start as \((0,0)\), North as +y, East as +x. 40 m N → \((0,40)\); 80 m W → \((-80,40)\); right turn (now facing N) and 50 m → \((-80,90)\). Step 2 — Track Y: 90 m N → \((0,90)\). Step 3 — Compare: Y is at the same northing as X, but 80 m to the East. Hence Y is 80 m to the East of X.

Argument I cites two concrete, large-scale consequences — prohibitive training costs and the loss of a year of national labour. These are tangible economic impacts that bear directly on the feasibility of a nationwide policy, making it a strong argument. Argument II merely asserts that army training "makes better citizens" without any concrete reasoning. It is a vague, subjective claim and therefore weak. Hence only Argument I is strong.

Option 1) It cannot be formed as the Square face and the with 6 lines are opposite to each other. Option 2) It can be formed. Option 3) It cannot be formed as the 5 dotted face and the Blank face are opposite to each other. Option 4) It cannot be formed as the face with 6 lines and the Square face are opposite to each other. Hence, option (dice) 2 can be formed. Note: This question was incomplete in the official question paper so we’ve made some changes in this question.

The shaded, portion represents the region of men who are not cyclists. Hence, ‘B, C, D’ represents men who are not cyclists.

Hence, the answer is figure 1.

Hence, the given question figure is hidden in option 1. Note: This question was incomplete in the official question paper so we’ve made some changes in this question.

Hence, the unfolded figure will be similar to option 2.

Hence, the mirror image of the given question figure will be similar to option 2.

List valid codes for each letter from the matrices: F: 40 only. Y: 65, 95. I: 11, 34. K: 01, 02, 03, 32, 33, 42. Option 4 — 40, 95, 11, 02 — gives F (Matrix-I 4,0), Y (Matrix-II 9,5), I (Matrix-I 1,1), K (Matrix-I 0,2), matching all four letters.

India's first synchronous census — conducted simultaneously across British India under W. C. Plowden — was held in 1881. It is regarded as the first official census and began the decennial census tradition that continues today. The 1867–72 enumeration was non-synchronous; 1921 marked the "Great Divide" in population growth; 1961 was the second census of the Republic.

The substitution effect isolates how a consumer reallocates consumption when relative prices change, with income compensated so the original bundle remains just affordable (Slutsky compensation). This removes the purchasing-power impact, leaving only the response to changed price ratios. The law of demand describes the total price-quantity relationship; problem of choice and optimal choice refer to general consumer decision-making, not compensated price effects.

Entry 9 of the State List (List II) in the Seventh Schedule reads “Relief of the disabled and unemployable,” placing it under the exclusive legislative competence of State legislatures. The Union List covers national matters (defence, banking); the Concurrent List covers shared subjects (education, marriage); there is no “Global” list.

Under Article 368, only Parliament can amend the Constitution by passing an Amendment Bill in both Houses, generally by a special majority, with state ratification required for federal-structure provisions. The Ministry of Defence and PMO are executive bodies; SEBI is a securities regulator — none has constituent power.

In Chola inscriptions, Devadana denotes land gifted to temples, with its revenue funding rituals, staff and temple maintenance. Vellanvagai was land of non-Brahmana peasant proprietors; Brahmadeya was land granted to Brahmanas; Shalabhoga supported schools. Only Devadana refers to temple grants.

Rajendra I (r. 1014–1044 CE) was the son and successor of Rajaraja I (r. 985–1014 CE), the Chola king who built the Brihadeeswarar temple at Thanjavur. Bindusara (Maurya), Devabhuti (Shunga) and Skandagupta (Gupta) belong to earlier North Indian dynasties unrelated to the Chola line.

Ladakh, lying in the rain-shadow of the Great Himalayas at high altitude, has extremely low precipitation and freezing winters — the defining traits of a cold desert. The Aravalli, Vindhya and Satpura are mountain ranges in north-western and central India, none of them Himalayan or desert.

Intercropping grows two or more crops in alternate rows, often sown at different times, so the ground stays covered for longer and raindrop impact and runoff are reduced — protecting topsoil from rain wash. Mulching covers soil with material, terrace farming reshapes slopes, and rock dams trap sediment in gullies — none involves alternate crop rows.

Each testis is divided by septa extending inward from the tunica albuginea into roughly 250 testicular lobules. Each lobule houses 1–3 seminiferous tubules where spermatogenesis occurs, with Leydig cells in the interstitium producing testosterone. The standard anatomical figure cited in NCERT and Gray’s Anatomy is about 250 per testis.

A moss spore germinates into a creeping, filamentous, photosynthetic protonema (first gametophyte stage). Buds on the protonema grow into the erect leafy shoot — the second, mature gametophyte stage that bears the sex organs. Agar and Chlorella are unrelated; protonema is the first stage, so the second is leafy.

Mollusca, Chordata and Annelida are recognised phyla of Kingdom Animalia. Coelomates is not a taxonomic rank — it is a grouping based on the presence of a true mesoderm-lined body cavity (coelom), a trait shared by many phyla including Annelida, Mollusca, Arthropoda and Chordata.

Even apparently smooth surfaces have microscopic peaks and valleys. When two surfaces touch, these irregularities interlock and form tiny adhesive junctions; breaking them as one surface slides over the other produces the resistive force called friction. Smoothness and gaps would reduce contact; density is a bulk property, not the contact-level cause.

A freely falling body moves under gravity alone, experiencing the constant acceleration \(g \approx 9.8\,\text{m/s}^2\) directed downward. Constant acceleration is the definition of uniformly accelerated motion, with velocity increasing by equal amounts in equal time intervals. Constant velocity/speed would need zero acceleration; non-uniform acceleration would need changing \(g\).

HHDD stands for Hybrid Hard Disk Drive — a drive that pairs a conventional spinning magnetic disk for bulk storage with a small non-volatile flash cache (typically 128 MB or more) that holds frequently accessed data for faster reads. “Hyper” and “Helium” variants are not standard terms for this HDD-plus-flash architecture.

Sulfurous acid contains sulfur in the +4 oxidation state and has the formula \(H_2SO_3\) — two hydrogens, one sulfur and three oxygens. It forms when \(SO_2\) dissolves in water. \(H_2SO_4\) is sulfuric acid (S in +6 state); the \(H_3\) formulas are not standard sulfur oxyacids.

The melting point is the temperature at which a solid changes to a liquid at a given (atmospheric) pressure. The temperature stays constant during the transition as the absorbed heat (latent heat of fusion) breaks the lattice bonds. Crystallisation is the reverse (liquid → solid); evaporation is liquid → gas; galvanisation is zinc coating — none is a melting temperature.

Commensalism is the ecological interaction in which one species (the commensal) benefits while the other (the host) is neither harmed nor benefited (+/0). Examples: barnacles on a whale, cattle egrets foraging near grazing cattle, orchids growing on tree branches. Predation (+/-) and parasitism (+/-) harm the second species; competition (-/-) harms both. Hence the correct answer is Commensalism.

The Ude Desh Ka Aam Nagrik (UDAN) scheme, launched in 2016 under the National Civil Aviation Policy, is the Regional Connectivity Scheme that caps fares (around Rs. 2,500 per hour of flight) to make domestic air travel affordable for middle-class citizens. Urja Ganga concerns gas pipelines, Ek Bharat Shrestha Bharat promotes inter-state cultural exchange, and Namami Gange targets river rejuvenation - none relate to aviation.

The hot air balloon was invented by the Montgolfier brothers, Joseph-Michel and Jacques-Etienne, French paper manufacturers. Their first public unmanned demonstration took place at Annonay, France on 4 June 1783, followed by manned flights later that year. The Wright brothers built the first powered airplane (1903); the Lisitsyn and Walton brothers are not credited with this invention.

At the 2016 Rio Olympics, the USA topped the medal tally with 121 total medals (46 gold, 37 silver, 38 bronze). Great Britain finished with 67, China with 70, and Russia with 56 - all well behind the USA's total.

The Group of Monuments at Hampi lies on the banks of the Tungabhadra River in Karnataka. It was the capital of the Vijayanagara Empire (14th-16th centuries) and was inscribed as a UNESCO World Heritage Site in 1986. Key structures include the Virupaksha and Vittala temples.

The Bharat Ratna, instituted on 2 January 1954, is India's highest civilian award, given for exceptional service of the highest order in any field of human endeavour. Padma Vibhushan and Padma Bhushan rank second and third among civilian honours, while Param Vir Chakra is the highest wartime military gallantry award, not a civilian one.

Statement 1: 'An Affair Downstairs' is by Sherri Browning - correct. Statement 2: 'White Teeth' (2000) is the debut novel of British author Zadie Smith - correct. Statement 3: 'Atonement' (2001) was written by Ian McEwan - correct. All three statements are accurate, so the answer is 1, 2 and 3.

In 2017, NASA's Hubble Space Telescope confirmed a second 'Great Spot' on Jupiter - a dark vortex in the upper atmosphere measuring roughly 24,000 km across and 12,000 km wide, distinct from the famous Great Red Spot. Saturn, Mars and Mercury do not host a feature matching this description.

The Sundarbans mangrove forest spans the Ganges-Brahmaputra delta and is shared by India and Bangladesh. The Indian portion is the Sundarbans National Park (West Bengal), while the adjoining Sundarbans Reserve Forest (SRF) - the world's largest contiguous mangrove tract and a UNESCO World Heritage Site - lies in Bangladesh.

Multiply each binary digit by its place value (powers of 2 from the right) and sum: \[10110_2 = 1\cdot2^4 + 0\cdot2^3 + 1\cdot2^2 + 1\cdot2^1 + 0\cdot2^0\] \[= 16 + 0 + 4 + 2 + 0 = 22\] Therefore 101102 = 2210.

Step 1 - Combined one-day work: \[\frac{1}{12}+\frac{1}{16}+\frac{1}{24}=\frac{4+3+2}{48}=\frac{9}{48}=\frac{3}{16}\] Step 2 - Time taken together is the reciprocal: \[T=\frac{16}{3}\text{ days}\] Therefore the answer is 16/3 days.

For a square of side \(s\), the diagonal is \(d = s\sqrt{2}\) (Pythagoras on the two equal sides). Given \(d = 10\): \[s=\frac{10}{\sqrt{2}}=\frac{10\sqrt{2}}{2}=5\sqrt{2}\text{ cm}\] Therefore the side is \(5\sqrt{2}\) cm.

Step 1 - Price after 40% discount on MP Rs. 1000: \[1000\times(1-0.40)=600\] Step 2 - Extra reduction from Rs. 600 to actual sale price Rs. 510 = Rs. 90. Step 3 - Additional discount % on the reduced price: \[\frac{90}{600}\times 100=15\%\] Therefore the additional discount is 15%.

The proportion \(x:3::y:9\) means \(\dfrac{x}{3}=\dfrac{y}{9}\). Cross-multiplying: \[9x=3y \;\Rightarrow\; y=3x\] Substituting into the target expression: \[\frac{y}{3x}=\frac{3x}{3x}=1\] Therefore the value is 1.

Step 1 - Number of boys: \(39-26=13\). Step 2 - Total weights: \[\text{Class}=48\times 39=1872\text{ kg};\quad \text{Girls}=42\times 26=1092\text{ kg}\] Step 3 - Boys' total: \(1872-1092=780\) kg. Step 4 - Boys' average: \[\frac{780}{13}=60\text{ kg}\] Therefore the average weight of the boys is 60 kg.

Step 1 — Find CP from the loss case: \[CP = \frac{SP \times 100}{100 - \text{Loss\%}} = \frac{2880 \times 100}{90} = 3200\] Step 2 — Apply 20% profit: \[SP = 3200 \times \frac{120}{100} = 3840\] Therefore the required selling price is Rs. 3840.

Let Geography marks be \(G\); then History \(H = G + 9\). Given \(H = 0.56(H + G)\), substitute: \[G + 9 = 0.56(2G + 9) = 1.12G + 5.04\] \[0.12G = 3.96 \implies G = 33\] Therefore Priya's Geography marks are 33.

Let Duronto's speed be \(S_D\) and Express's be \(S_E\); \(T_D = 720/S_D\). Condition 1: \(\frac{720}{S_E} - \frac{720}{S_D} = 6\) Condition 2: \(\frac{720}{S_D} - \frac{360}{S_E} = 2\) Adding: \(\frac{360}{S_E} = 8 \Rightarrow S_E = 45\). Substituting: \(\frac{720}{S_D} = 10 \Rightarrow S_D = 72\). Therefore Duronto's speed is 72 km/hr.

Yearly: \(CI = 1000\times 0.10 = 100\). Half-yearly (rate 5%, 2 periods): \[A = 1000(1.05)^2 = 1102.50,\quad CI = 102.50\] Difference \(= 102.50 - 100 = 2.50\). Therefore the difference is Rs. 2.5.

Expand the bracket: \[7x - \tfrac{3}{2}(4x - 9) = 7x - 6x + \tfrac{27}{2} = x + 13.5\] Set equal to 6.5: \[x + 13.5 = 6.5 \implies x = -7\] Therefore \(x = -7\).

Use the identity \(a^3 + b^3 = (a+b)^3 - 3ab(a+b)\). Substitute \(a+b = 8\) and \(ab = 15\): \[a^3 + b^3 = 8^3 - 3(15)(8) = 512 - 360 = 152\] Therefore \(a^3 + b^3 = \mathbf{152}\).

Let the number be \(x\). Then \(x + \frac{4}{x} = \frac{17}{2}\). Multiply through by \(2x\): \[2x^2 - 17x + 8 = 0 \implies (2x-1)(x-8) = 0\] Roots are \(x = 8\) or \(x = \tfrac{1}{2}\). Only 8 appears in the options.

Use \(a_n = a_1 + (n-1)d\). From \(a_9 - a_5 = 4d = 13 - 7 = 6\), so \(d = \tfrac{3}{2}\). Then \(a_1 = a_5 - 4d = 7 - 6 = 1\). \[a_{15} = 1 + 14 \times \tfrac{3}{2} = 1 + 21 = 22\] Therefore the 15th term is 22.

Reflection in the horizontal line \(y = c\) keeps the x-coordinate and maps \(y \to 2c - y\). With \((x, y) = (6, -3)\) and \(c = 2\): \[y' = 2(2) - (-3) = 7\] Therefore the reflected point is (6, 7).

By the section formula, for A dividing BC in ratio \(m:n = 2:5\): \[y_A = \frac{m \cdot y_C + n \cdot y_B}{m+n} \implies 2 = \frac{2y + 5(6)}{7}\] \[14 = 2y + 30 \implies y = -8\] Therefore \(y = \mathbf{-8}\).

A line cuts the X-axis where \(y = 0\). Substitute into \(2x - 3y = 6\): \[2x - 0 = 6 \implies x = 3\] Therefore the line meets the X-axis at (3, 0).

When the altitude from the right angle meets the hypotenuse, the geometric mean (altitude) theorem gives: \[BD^2 = AD \times DC = 4 \times 9 = 36\] \[BD = \sqrt{36} = 6 \text{ cm}\] Therefore \(BD = \mathbf{6}\) cm.

Standard values: \(\tan 45^\circ = 1\) and \(\operatorname{cosec} 60^\circ = \tfrac{2}{\sqrt{3}}\). \[1 + \frac{2}{\sqrt{3}} = \frac{\sqrt{3} + 2}{\sqrt{3}} = \frac{(\sqrt{3}+2)\sqrt{3}}{3} = \frac{3 + 2\sqrt{3}}{3}\] Therefore the value is \(\dfrac{3 + 2\sqrt{3}}{3}\).

Angles sum to \(180^\circ\): \(\angle X = 180^\circ - 90^\circ - 60^\circ = 30^\circ\). \[\operatorname{cosec} X = \operatorname{cosec} 30^\circ = \frac{1}{\sin 30^\circ} = \frac{1}{1/2} = 2\] Therefore \(\operatorname{cosec} X = \mathbf{2}\).

Use the identity \(\operatorname{cosec}^2\theta - \cot^2\theta = 1\). \[\cot^2\theta = \left(\tfrac{17}{8}\right)^2 - 1 = \tfrac{289 - 64}{64} = \tfrac{225}{64}\] \[\cot\theta = \tfrac{15}{8}\] Therefore \(\cot\theta = \mathbf{\tfrac{15}{8}}\).

As seen from the given graph, the movie C grossed the second highest box office collections

Box office collections of movie D = Rs. 60 crores Box office collections of movie B = Rs. 100 crores ∴ Required percentage = [(100 – 60)/100] × 100 = 40%

Box office collections of movie F, A and D = 90 + 40 + 60 = Rs. 190 crores Box office collections of movie B, D and F = 100 + 60 + 90 = Rs. 250 crores Box office collections of movie B and D = 100 + 60 = 160 Box office collections of movie A, B and F = 40 + 100 + 90 = Rs. 230 crores ∵ Box office collections of movie C = Rs. 250 crores ∴ Box office collections of movie C is equal to combines collections of movies B, D and F

Box office collections of movie A = Rs. 40 crores Box office collections of movie E = Rs. 260 crores If producer gets 60% of box office collections, ∴ Producer of movies A and E will get = 60% of (40 + 260) = 0.6 × 300 = Rs. 180 crores

The error lies in segment "While he went beside". The preposition beside means "next to" and does not convey agreement or compliance. The intended sense requires the phrasal verb go along with, giving "While he went along with our decisions." The other segments are grammatically sound.

Part (1) "The after morning" is incorrect. Standard English uses "The next morning" or "The morning after" to refer to the following morning. "After morning" is not an accepted noun phrase. Parts (2) and (3) are grammatically correct, so the error is in segment (1).

Perverse means turned away from what is right or natural — abnormal and morally wrong. A psychopath's pleasure in torturing animals is precisely this kind of distorted enjoyment. Agreeable, happy, and reasonable all carry positive or neutral connotations that contradict the cruel context.

Gesticulate means to make expressive movements with the hands or arms, especially to convey strong emotion. This exactly fits expressing feelings with one's hands. Participate means take part; immolate means kill by burning; intoxicate means make drunk — none involve hand movement.

Fossilize means to become rigid, hardened, or fixed in an outdated form. Amalgamate means to merge or combine into one mass — both share the sense of distinct parts becoming a single fixed whole. Dissolve and liquefy denote turning to liquid; flex means bend — all opposite to fossilizing.

Depict means to represent or describe the features of something in words or images. Characterize means to describe the distinctive qualities of someone or something — the closest match. Conceal and suppress mean to hide or stop; distort means to misrepresent.

Differ means to disagree or hold a different opinion. Its antonym is Concur, meaning to agree or share the same view. Alter means to change; digress means to stray from the topic; vary is a synonym of 'differ', not its opposite.

Salve is a soothing, healing ointment — something that eases or remedies. Blockage means an obstruction that prevents flow or relief, the opposite of soothing/healing. Cerate and liniment are types of medicinal preparations; remedy is a near-synonym, not an antonym.

To gnash your teeth literally means to grind the teeth together, an action associated with intense anger or fury. Idiomatically it signifies expressing rage or frustration when one feels powerless. It has no connection with brushing, laughter, or biting.

The idiom "let something slip through one's fingers" means to fail to seize or take advantage of an opportunity that was within reach, usually through carelessness or hesitation. Hence the correct meaning is "to waste an opportunity to achieve something." The other options are literal or unrelated readings.

The pronoun "it" in "(to do it)" is redundant because the interrogative "what" already functions as the object of "do". The natural form after "would like" is the infinitive without an extra object: "What would you like to do for your birthday?" Hence the improvement is to do.

After the modal phrase "must be", an adjective or past participle is required to describe the subject's state. The idiom "be mistaken" means "be wrong" and uses the past participle, giving "You must be mistaken." "Be mistake" (noun), "be mistakenly" (adverb), and "be mistook" (simple past) are all ungrammatical here.

Thorough means complete with attention to every detail — an exact match for the given phrase. Lackadaisical (lacking effort), lax (not strict or careful), and cursory (hasty, superficial) all convey the opposite idea of inattention to detail.

Volition means the faculty or power of using one's will — the act of consciously choosing or deciding. Antagonism means hostility, aversion means strong dislike, and rejection means refusal — none denote the underlying power of the will itself.

The correct spelling is juxtapose, a verb meaning to place two things side by side for comparison or contrast. The other options misspell the first syllable ("jux-") as "juk-", "jax-", or alter the second syllable's vowels ("-puse" instead of "-pose").

The correct spelling is amusement — one 'm' and the noun-forming suffix '-ment' (from the verb 'amuse'). The other options either double the 'm' ('ammusement', 'ammusemant') or use the wrong suffix '-ant' ('amusemant'), both of which are misspellings.

The opener "Evidently, it was too" needs an adjective — Z ("dry for game, and with the exception") fits. "With the exception" demands "of", so X ("of a deadly-looking cobra or") follows. "Cobra or" needs completion by Y ("two we saw no reptiles"). Full sentence: "Evidently, it was too dry for game, and with the exception of a deadly-looking cobra or two we saw no reptiles." Order: ZXY.

The opener "Some of these" needs a noun-subject — Z ("rocks rise to the") fits. "To the" demands a noun, supplied by X ("height of more than"). "More than" needs a quantity, supplied by Y ("2000 feet above the sea"). Full sentence: "Some of these rocks rise to the height of more than 2000 feet above the sea." Order: ZXY.

The active sentence "I will wash the car every Sunday" is in the simple future tense. The passive form uses will be + past participle: "will be washed". The object 'the car' becomes the subject, the agent 'by me' follows, and the time phrase 'every Sunday' is retained: "The car will be washed by me every Sunday." Options 1–3 use wrong tense or unnatural structures.

Imperative sentences in direct speech are reported using an infinitive phrase after a suitable reporting verb. "Said" changes to "shouted" to match the alarmed tone, and the implied listeners become "the crowd". The command "Catch him!" with the identification "Thief! Thief!" combines into "to catch the thief". Hence: "The watchman shouted to the crowd to catch the thief."

The passage states Arastu "belongs to the family that owned the famous A A Husain bookstore in Abids" — linking him to a bookseller family, not the Nizam's royal lineage. Hence the claim that "He was a descendent of the Nizam's family" is false. The other options (librarian at Falaknuma, bookstore-owning family, friend of Anuradha Naik) are all supported by the passage.

The passage explicitly describes the library's "walnut carved high roof", which is said to be an imitation of the one at Windsor Castle. Rosewood and mahogany refer to the library's overall furnishing, not the roof carvings. Sandalwood is not mentioned. Hence the roof carvings were made of walnut.

The passage states: "On his very first day as the librarian at the magnificent Taj Falaknuma Palace, Asif Husain found a reference book on 'How to paint grass' by Alfred East." Anuradha Naik is Husain's historian friend, not an author. Mark Twain and Charles Dickens are not mentioned. Hence the author is Alfred East.

The passage states that the palace "couldn't find the right person to do justice to the treasure trove of books collected by the Nizam's family over several decades." Anuradha Naik only pointed out the vacancy, and Asif Husain Arastu was hired as librarian — neither collected the books. Hence the collectors were the Nizam's family.

The passage states: "the walnut carved high roof... is supposedly an imitation of the one at Windsor Castle." This roof belongs to the library. The 101-seater dining table, banquet hall, and library furniture are mentioned but never linked to Windsor Castle. Hence the answer is the library's roof.
