R: many of us remain largely oblivious to
S: the complex ways in which
- C. RPSQ
- B. SQRP
- A. RPQS
- D. QSRP
व्याख्या: The main clause starts with 'many of us remain largely oblivious to' (R). Oblivious to what? 'the subtle yet profound influence' (P). What influence?

24. Rearrange the following parts (P, Q, R, S) to form a coherent paragraph.
P: When this encrypted data is stolen, it is rendered useless to the thieves without the corresponding decryption key.
Q: Cryptography is the practice of securing communication from adversaries.

S: This process of conversion is called encryption.
- B. QSRP
- C. RQSP
- A. QRSP
- D. QRPS
व्याख्या: Q provides a general definition of cryptography. R explains the fundamental principle of how it works. S gives the specific name ('encryption') for 'This process of conversion' described in R. P explains the practical benefit of this process, showing what happens to stolen encrypted data.
25. Rearrange the following parts (P, Q, R, S) to form a coherent paragraph.
P: This phenomenon is not merely an aesthetic choice but a survival mechanism.
Q: Many animals in the natural world have evolved to blend in with their environments.
R: By matching their surroundings, they can evade predators or ambush unsuspecting prey more effectively.
S: This adaptive trait is known as camouflage.
- C. QPSR
- D. QRPS
- A. QSPR
- B. QSRP
व्याख्या: Q makes a general observation about animals blending in. S gives the scientific term ('camouflage') for 'This adaptive trait'. P then elaborates, stating that 'This phenomenon' is a survival mechanism. R explains how this mechanism works ('By matching their surroundings...').
26. Rearrange the following parts (P, Q, R, S) to form a coherent paragraph.
P: Its themes of totalitarianism, surveillance, and the manipulation of truth have become increasingly relevant in the digital age.
Q: George Orwell's novel 'Nineteen Eighty-Four', published in 1949, was a work of dystopian fiction.
R: It depicted a bleak future where a tyrannical regime, led by 'Big Brother', exercises absolute control over every aspect of human life.
S: Consequently, the term 'Orwellian' has entered the lexicon to describe policies or conditions reminiscent of the society he portrayed.
- D. QSPR
- A. QRPS
- C. RQPS
- B. QPSR
व्याख्या: Q introduces the novel, its author, and genre. R describes the plot of 'It' (the novel). P explains the novel's enduring relevance by listing its themes. S describes the long-term cultural impact ('Consequently...') of the novel, which stems from its powerful themes mentioned in P.
27. Rearrange the following parts (P, Q, R, S) to form a coherent paragraph.
P: Some historians attribute the collapse primarily to internal factors like political corruption, economic decay, and social unrest.
Q: The fall of the Roman Empire was not a single event but a complex process that unfolded over several centuries.
R: Others place greater emphasis on external pressures, such as barbarian invasions and military overreach.
S: In reality, it was likely a confluence of all these factors that gradually eroded the empire's foundations.
- A. QPRS
- D. QPSR
- B. QRPS
- C. QSPR
व्याख्या: Q makes a general statement about the fall of Rome. P presents one school of thought regarding the cause ('internal factors'). R presents a contrasting school of thought ('Others place greater emphasis on external pressures'). S provides a synthesis, concluding that 'it was likely a confluence' of the factors mentioned in both P and R.
28. Rearrange the following parts (P, Q, R, S) to form a coherent paragraph.
P: However, this very isolation has allowed unique and fragile ecosystems to develop, many of which are now threatened by climate change.
Q: Antarctica is the Earth's southernmost continent, a vast, ice-covered landmass.
