Multiple choice

Directions: In the question below, the first and the last (correctly ordered) sentences are numbered 1 and 6. The rest of the passage is split into four parts labelled B, C, D and E. These four parts are not given in the proper order. Choose the correct combination among the four alternatives mentioned to give the correct order.

  1. As science fiction established in the early 20th century, destinations such as the Moon, Mars, Venus, and other bodies within the Solar System began to seem stale. B. This tendency became predominant once the exploration of the Solar System was complete enough to conclusively demonstrate the unlikelihood of any highly developed form of extraterrestrial life here. C. Authors invoked a variety of mechanisms for superluminal travel and placed their stories on worlds in planetary systems around other stars. D. This was an innovation that gave them the freedom to construct exotic fictional planets and themes. E. Although some of the stars named in works of science fiction are purely imaginary.
  2. Yet many authors and artists have preferred to use the names of real stars that are well known to astronomers, and indeed the lay public.

  1. BCDE

  2. DBCE

  3. CDBE

  4. EBCD
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

‘Destinations such as ….began to seem stale’ in 1 is followed by ‘authors invoked a variety of mechanisms’ in C. ‘innovation’ in D refers to ‘mechanisms’ in C, ‘this tendency’ in B refers to 'freedom to construct' in D. Thus, we get CDB link. ‘Although….purely imagery’ in E is complemented by ‘yet…real stars’ in 6.
