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: C
Concept
In a sentence-rearrangement (para-jumble) question, first find the sentence that sets the scene without leaning on any pronoun or connector that points backward — that is always the opening sentence. Then trace the explicit forward links (referential pronouns like ‘this/these’, transitional markers, cause-and-effect order) until you reach a sentence whose reference is fully grounded in the sentence right before it, with nothing left dangling — that sentence, which draws a conclusion or comparison from an earlier detail rather than introducing a new one, is the last sentence of the paragraph.
Application
C sets the scene with no back-reference: ‘During the 1960s, the Space Race... was accelerating’ — this is the natural opening sentence.
B follows as a direct outcome of that accelerating Space Race: ‘The National Aeronautics and Space Administration (NASA) was established.’
E continues the timeline: once NASA existed, ‘Funds for space endeavours were abundant, and plans for a large space telescope... were underway.’
F specifies the technical design that those plans produced: ‘The designs called for a 2.4-metre primary telescope mirror...’
A elaborates with a magazine's description of the resulting performance: the resolving power ‘equivalent to being able to distinguish the left and right headlights of a car in California seen from New York...’
D opens with ‘This was...’, referring directly to the resolving-power figure just stated in A, and closes the paragraph with a comparative remark: ‘a tenfold increase over the atmospheric limit.’
Cross-check
Read D on its own: ‘This was at least a tenfold increase over the atmospheric limit.’ The demonstrative ‘This’ has no antecedent unless the resolving-power comparison in A comes immediately before it, and no other sentence supplies a quantity for ‘a tenfold increase’ to refer to. That confirms D can only sit right after A, at the very end of the paragraph.
Why not the others
F (the 2.4-metre mirror design) introduces a new technical detail rather than concluding one — the resolving-power figure and its comparison still need to follow it, so it cannot be the closing sentence.
E (funds and early plans for the LST) is a setup step in the middle of the narrative — the specific design and its performance are still to come.
C (the Space Race backdrop) is the paragraph's opening scene-setter that everything else is built from — it cannot be the concluding sentence.
The correct order of the paragraph is C–B–E–F–A–D, so the last sentence is D.
