General Aptitude · Verbal Aptitude: Grammar and Vocabulary · 2 marks · Multiple choice

Read the passage: The James Webb telescope gives humankind unprecedented access to the depths of time by imaging very old stars formed almost 13 billion years ago. Astrophysicists and cosmologists believe this space odyssey may shed light on dark matter. Dark matter is supposed to interact only through gravity, not electromagnetic,weak or strong interactions; this may justify the epithet “dark.” Based on the passage, which statement is FALSE?

  1. No other telescope has captured images of stars older than those captured by James Webb.
  2. People other than astrophysicists and cosmologists may also believe in dark matter.
  3. James Webb could be useful in dark-matter research.
  4. If dark matter interacted through the strong interaction, the epithet “dark” would be justified.

Show answer and explanation

Correct answer: (D) If dark matter interacted through the strong interaction, the epithet “dark” would be justified.

Explanation

The passage links the epithet to the absence of the listed non-gravitational interactions. D reverses that supplied explanation by treating strong interaction as justification. B is not excluded and C is directly supported. The official reading selects **D**; A interprets “unprecedented access” as a record-age claim, although that precise comparison is stronger than the wording alone establishes.
