GATE | GATE CS 2019 | Question 2

The search engine’s business model ________ around the fulcrum of trust.
(A) revolves
(B) plays
(C) sinks
(D) bursts

Answer: (A)


  • revolve: move in a circle on a central axis.
  • play: engage in activity for enjoyment and recreation rather than a serious or practical purpose.
  • sink: go down below the surface of something, especially of a liquid; become submerged.
  • burst: break open or apart suddenly and violently, especially as a result of an impact or internal pressure.

fulcrum means the point against which a lever is placed to get a purchase, or on which it turns or is supported. SO, revolve is most appropriate.

Option (A) is correct.
