Key Points

  • Sentence R comes first because it directly refers to “the united stream,” which logically follows S1 where the union of the two streams is mentioned.
  • "The united stream strikes in a north-easterly direction through Mysore and skirts the adjacent districts."
  • Sentence S follows as it provides additional physical details about the headstreams of the river.
  • "The bed of both the headstreams of the Tungabhadra is rocky."
  • Sentence P is placed next because it describes the nature and flow of the river.
  • "The river is perennial in character and comes down in frequent heavy rushes during the rains."
  • Sentence Q comes last as it provides historical information about how the river was dammed, which naturally leads to S6 about its historic significance.
  • "The rain-bearing river was dammed by the rulers of Vijayanagara near Hampi for watering the palaces and gardens of that great city."
  • The correct sequence is RSPQ.

Correct answer

Answer: (d)D.

PRSQ

Why this answer is correct

The correct answer is 'PRSQ'.

 

Key Points

  • S1 introduces the topic: the history of India's struggle for freedom as an "enthralling" story.
  • P follows S1 immediately because it uses the pronoun "It" to refer back to the "history/struggle" and explains why it is enthralling (it has drama and excitement of an epic tale).
  • R connects directly to P by using the phrase "As in epics," expanding on the nature of this struggle by mentioning heroism and sacrifice.
  • S provides further details of the content of these historical accounts (loyalty, allegiance, and high ideals).
  • Q introduces a contrast using "And yet," shifting from the exciting nature of the story to the dry way it is presented in textbooks. This leads perfectly into S6, which suggests a "more vibrant retelling" is needed.

Therefore, the correct sequence is Option 4 (PRSQ).

 

Complete Sentence: "The history of India's struggle for freedom is an enthralling one. It has all the drama and excitement of an epic tale. As in epics, heroism was often accompanied by extreme sacrifice. Accounts of this period are loaded with tales of loyalty, allegiance, high ideals and peaceful protests. And yet, in most history textbooks, what students encounter are facts, figures, names and numbers. A more vibrant retelling is perhaps required of this tumultuous period of our history."

 

Additional Information

  • To solve jumbled sentences (Sentence Rearrangement), look for pronoun antecedents (like "It" in P referring to "history" in S1).
  • Identify keyword repetitions (the word "epic" connects P and R).
  • Look for transition words (like "And yet" in Q) which indicate a shift in thought or a conclusion that ties into the final sentence (S6).

Answer: (d)D.

RSQP

Why this answer is correct

The correct answer is Option 4 i.e. RSQP.

 

Key Points

  • The passage is about Louis XVI’s accession and the financial crisis in France leading up to his reign and policies.
  • Sentence R comes first after S1 because it directly follows the marriage information with the fact that Louis XVI ascended the throne in 1774, maintaining clear chronological order:
  • “In 1774, Louis XVI ascended the throne of France at the age of 20.”
  • Sentence S follows as it introduces the general financial condition of France, giving background to the economic situation Louis XVI inherited:
  • “Long years of war had drained the financial resources of France.”
  • Sentence Q comes next because it specifies the immediate war before his ascension and quantifies the debt, logically elaborating on the financial strain mentioned in S:
  • “The ascension was preceded by a war that added more than a billion livre to a debt that had already risen to more than 2 billion livre.”
  • Sentence P is the fourth as it describes the consequence of this heavy debt in terms of lenders increasing interest rates, completing the picture of the financial crisis:
  • “Furthermore, lenders, who gave the state credit, now began to charge 10 per cent interest on loans.”
  • The correct sequence is therefore RSQP, which fits smoothly between S1 and S6 and maintains both logical and chronological coherence.

Correct answer

Answer: (c)C.

QPRS

Why this answer is correct

The correct answer is 'QPRS'.

 

Key Points

  • S1 introduces Montesquieu as a great philosopher.
  • Q follows S1 by introducing his famous work, The Spirit of the Laws, and his core theory of the separation of powers into three branches (Legislative, Executive, and Judiciary).
  • P explains his vision for social power distribution, specifically how that power should be shared between the king, the nobles, and the Third Estate.
  • R builds on the idea of power-sharing by introducing the mechanism of "checks and balances" to prevent any single class from becoming too dominant.
  • S provides the logical result of this system: the prevention of tyranny and the safeguarding of individual liberty. The phrase "If this was done" in S refers back to the implementation of the constitution mentioned in R.
  • S6 concludes by noting his preference for a constitutional monarchy modelled after the English system.

Therefore, the correct sequence is Option 3 (QPRS).

 

Complete Sentence: "Montesquieu was a great philosopher of his time. In his book The Spirit of the Laws, he propagated the theory of separating powers into three branches of government the Legislative, the Executive and the Judiciary. He wanted power to be shared between the king, the nobles, and the Third Estate. To prevent any one of the three classes from becoming too powerful, Montesquieu suggested the making of a new constitution based on checks and balances. If this was done, he argued, there would be no tyranny and the liberty of the individual could be safeguarded. He supported constitutional monarchy in France like the English one."

 

Additional Information

  • Logical Progression: Always look for a flow from a general theory (Q: Separation of Powers) to specific implementation (R: Checks and Balances).
  • Pronoun/Demonstrative Links: In sentence S, the phrase "If this was done" is a crucial link that must follow the proposal of a specific action (making a new constitution in R).
  • Chronological/Work Intro: It is standard in biographical passages to introduce a person's major work (The Spirit of the Laws) early in the sequence.

S1: Glaciation has important effects on the landscape beyond the direct modifications created by ice erosion and deposition.

S6: At the same time, ice advanced from the Welsh mountains into the Vale of Evesham and combined with northern ice to pond up a large proglacial lake covering much of the Midlands.

P: One example is that glaciation frequently disrupts pre-existing drainage lines, initiating a new pattern persisting after the ice has disappeared.

Q: The Midlands, what is now the Coventry/Warwick area, was formerly drained by the head waters of the River Soar, flowing into the Trent south of Nottingham.

R: Two well-documented instances of such effects occur in England.

S: During glaciation, the valleys of Soar and Trent were occupied by ice advancing from the north.

RPQS

Why this answer is correct

The correct answer is Option 2 i.e. RPQS

 

Key Points

  • R comes first as it signals a shift from the general statement in S1 to specific documented instances in England, aligning the reader’s expectations.
  • P follows by defining the nature of the glaciation effect (disruption of drainage), establishing the thematic lens for the examples.
  • Q is next because it describes the pre-glaciation drainage of the Midlands (Coventry/Warwick area) by the River Soar, setting the baseline.
  • S concludes the example with the glaciation phase, where northern ice occupied the Soar and Trent valleys, preparing for S6’s outcome (the proglacial lake).

 

Coherent sequence within the passage:

P: Sediments and fossil in the poles tell us a great deal about the environment in which they were laid down.

Q: We must, of course, bear in mind when interpreting this information that, because of the movement of the continents, no one latitude of the Earth has necessarily gone through such marked climatic vicissitudes.

R: Nevertheless, even allowing for this factor, one of the most remarkable discoveries about the climate change of the past is that the two poles of the Earth have been free of ice for at least 90 per cent of the known history of the planet.

S: We may find in close proximity to one another, coal deposits indicating the humid conditions of the tropics, red sandstones laid down in deserts and morainic materials reflecting polar conditions.

Why this answer is correct

The correct answer is Option 3 i.e. SQRP.

 

Key Points

  • S logically follows S1 by providing concrete examples of how different types of deposits (coal, sandstone, morainic materials) reflect varied climatic conditions, reinforcing the idea that rocks and deposits are key evidence.
  • Q introduces a necessary caution: due to continental drift, climatic interpretations based on latitude must be made carefully. This adds nuance to the evidence mentioned in S and P.
  • R begins with “Nevertheless,” signaling a contrast or conclusion. It emphasizes a key finding: the poles were ice-free for most of Earth’s history, despite the complexities mentioned in Q.
  • P then zooms in on polar sediments and fossils, reinforcing the insight from R and smoothly transitioning into S6, which summarizes the broader implication about warm climatic conditions.

Therefore, the correct sequence is SQRP.

P: Individual shifts rely on opportunity, ecological access, and the development of a new adaptation.

Q: Characteristically these shifts are rapid and are followed by a bout of adaptive radiation into the new ecological zone -for example, with the emergence of life on land.

R: Within each period, natural selection has created a vast array of adaptive experiments culminating in a breakthrough to a new biological system that may cross the ecological barrier to the next period.

S: Every breakthrough of shift in dominance is dependent on ones that have occurred before so that the process of evolution is progressive.
