Rearrange the following six sentences/ group of sentences (A), (B), (C), (D), (E), (F) in the proper sequence to form a meaningful paragraph; then answer the questions given below them
A.
According to National Geographic’s Imaging Space and Time, the resolving power of the deep space telescope would be ‘equivalent to being able to distinguish the left and right headlights of a car in California seen from New York, or features less than 1/30,000th the size of the full moon.
B.
The National Aeronautics and Space Administration (NASA) was established.
C.
During the 1960s, the Space Race between the then–Soviet Union and the United States was accelerating.
D.
This was at least a tenfold increase over the atmospheric limit.’
E.
Funds for space endeavours were abundant, and plans for a large space telescope, by then designated the LST, were underway.
F.
The designs called for a 2.4–meter primary telescope mirror which could be transported into space by one of NASA’s rockets.

Show answer & explanation
Correct answer: B
Concept
In a sentence-rearrangement (para-jumble) passage, sentences link through topic introduction, chronological/causal flow, and reference words such as ‘this’, ‘these’, or ‘by then’ that point back to an idea in the sentence just before them. To find the correct order, first isolate the sentence that opens the topic without depending on any earlier reference, then chain the rest by matching each sentence’s opening cue to the idea the previous sentence just closed.
Application
C introduces the era and backdrop — the 1960s Space Race — which is the topic-opening sentence since it needs no prior reference.
B follows, naming NASA’s founding as the institutional actor that emerges from that competitive backdrop.
E continues — once NASA exists, funds are abundant and plans for a large space telescope (the LST) are underway.
F details the design specifications that come out of those plans (a 2.4-metre mirror, to be launched by a NASA rocket).
A then quotes National Geographic’s description of the resulting telescope’s resolving power.
D closes the paragraph — its opening word ‘This’ refers back to the resolving-power figures just stated in A, concluding it was a tenfold increase over the atmospheric limit.
So the full order is C–B–E–F–A–D. The question asks for the ‘last second sentence’, i.e. the second-to-last (fifth of six) sentence, which is A.
Cross-check
Reading the chain back to front confirms it: D’s ‘This’ can only point to a quantity or description already given, which is exactly what A supplies immediately before it; and F’s design details logically precede — rather than follow — the capability (resolving-power) description in A. No other ordering keeps every reference resolved, so A is the only sentence that can occupy the fifth position.
