Solved Representative Practice Questions (CDS Pattern)
Practice with genuine CDS-style questions drawn from our interactive quiz question sets:
Question 1 (Spotting Errors)
Neither the commanding officer (A) / nor his subordinate officers (B) / was present during the inspection. (C) / No error (D)
Correct Answer: (C) was present during the inspection
Explanation: Under the rule of proximity for correlative conjunctions (*neither... nor*), the verb agrees with the subject closest to it. Here, the closer subject is subordinate officers (plural); therefore, the singular verb was must be replaced by the plural verb were.
Question 2 (Synonyms in Context)
The treaty was signed in an attempt to mitigate the escalating tension along the border.
- aggravate
- alleviate
- prolong
- intimidate
Correct Answer: (B) alleviate
Explanation: Mitigate means to make something less severe, harmful, or painful. Its closest synonym is alleviate. Aggravate is its antonym.
Question 3 (Ordering of Words - PQRS)
Reorder the fragments to form a grammatically coherent sentence:
(P) despite facing overwhelming adversity
(Q) the battalion held their ground
(R) until reinforcements arrived at dawn
(S) without retreating an inch
- Q-S-P-R
- P-Q-S-R
- R-P-Q-S
- S-Q-P-R
Correct Answer: (B) P-Q-S-R
Explanation: "Despite facing overwhelming adversity (P), the battalion held their ground (Q) without retreating an inch (S) until reinforcements arrived at dawn (R)." This sequence maintains clear cause, action, manner, and temporal sequence.
