Question

S1: John Young, the astronaut, piloted the 75-ton space-shuttle, Columbia.
S6: And it moved smoothly to a stop as the crew rushed to greet it.
P: The Columbia, however, landed safely at the Edwards Air Force base in the Mojave desert.
Q: The space-shuttle circled the Earth 36 times.
R: It was dangerous because a re-usable craft was being used now.
S: This flight was fraught with dangers.
The proper sequence should be:
a) P-Q-S-R
b) S-Q-R-P
c) P-R-S-Q
d) Q-S-R-P

Answer 1

Hint: In order to choose the correct option, understand the general idea that the passage is conveying with the sentences given in the question. Then, arrange the remaining sentences.

Complete answer:
 In the given question, we are provided with two sentences, one that starts and the other that ends the passage. We also have four other sentences that we have to place in the correct order to make the passage meaningful.
The passage starts with a brief description of the astronaut and the space shuttle. The last sentence describes a safe landing of the space shuttle.
The sentence after the first sentence must be something that describes the event more, hence, it is ‘Q’.
Since the last sentence is about landing, let us look for a sentence that talks about the same to place before it. Hence, it is ‘P’, so that would be last sentence from the given four.
The danger is addressed in ‘S’ and elaborated in ‘R, hence, ‘S’ must be placed before ‘R’.
Hence, the order is ‘Q-S-R-P’. Therefore, the correct answer is option ‘D’ as it is the only option with this order.

Note:
If you are unsure of the placements, fix the position of two sentences, this will help you to find the position of the rest.
