Q:

In the following items, each passage consists of six sentences. The first and the sixth sentence are given in the beginning as S1 and S6. The middle four sentences in each have been removed and jumbled up. These are labeled P, Q, R and S. You are required to find out the proper sequence of the four sentences and mark your response accordingly on the Answer Sheet.

S1 :The boy felt his way up the creaking stairs through thick darkness.
S6:He was just telling himself he was safe when the door was flung open and the gaunt old man grabbed his shoulder.
P:All he had to do was just get past the central door on the landing.
Q:He stopped as the great clock below whined for a few seconds and gave out a single, solemn stroke.
R:His eyes were raised to the faint moonlight that shone above the landing.
S:He hesitated as the sound died down and then crept on, thinking that if they could sleep through that, they would sleep through any noise he could make.

The proper sequence should be 

A) P Q S R B) R Q S P
C) P R Q S D) R Q P S
 
Answer & Explanation Answer: D) R Q P S

Explanation:

The starting statement talked about how the boy managed to climb the stairs despite of thick darkness. So, the continuing statement would be talking about his landing and how his eyes were raised to moonlight. So, the next statement in continuation would be the statement R. This eliminates option (a) and (c). The next statement would be Q. The next statement would be talking about how he managed to pass through the central door and how he was getting afraid with the noise. So P follows Q and S would be the concluding statement. Thus, the correct sequence is RQPS.
