The GATE Grind

GATE 2022 XH2 (English) – Question 15

Reasoning and Comprehension · Verbal reasoning and comprehension · 1 mark · Multiple choice

The Arecibo telescope does not resemble what most of us think of when we hear the word telescope. Its reflective surface covers an area of 20 acres, which is quite remarkable. Dangling above it are towers and cables, sub-reflectors and antennas, all of which can be positioned using 26 motors to transmit radio waves and receive echoes with astonishing precision.

From the passage, it can be inferred that most telescopes

  1. are not as large as Arecibo
  2. do not have reflective surface
  3. cannot be re-positioned
  4. strictly have 26 motors
