In the following question, a statement/group of statements is given followed by some conclusions. Without resolving anything yourself, choose the conclusion which logically follows from the statement(s).

Statement - Only guilty singers were arrested. Narendra and Arvind were among those arrested.

  • A.All singers are guilty.
  • B.All arrested people are singers.
  • C.Narendra and Arvind were not singers.
  • D.Narendra and Arvind were guilty.

Answer: D

Correct answer: Narendra and Arvind were guilty.

The word only makes the inference valid: if the arrested set contains none but guilty singers, then anyone arrested is a guilty singer, and Narendra and Arvind were arrested. The other three reverse or overextend the classes - that all singers are guilty, that all arrested people are singers, or that these two were not singers - none of which follows from a statement about who was arrested.
