Q:

A statement is given followed by three inferences numbered I, II, and III. Consider the statement to be true even if it is at variance with commonly known facts. You have to decide which of the inferences, if any, follow from the given statement.

Statement

Donald Trump began the week facing accusations of treason over his embrace of Vladimir Putin and ended it with a middle finger to his many critics by inviting the Russian autocrat to the White House.

Inferences:

I. America and Russia are not allies.
II. No prior American President has ever
embraced a Russian counterpart.
III. Russian President, Vladimir Putin,
has been a long-time US enemy.

A) Only I can be inferred B) Both I and II can be inferred
C) Only III can be inferred D) Both I and II can be inferred
 
Answer & Explanation Answer: C) Only III can be inferred

Explanation:

Only III can be inferred. We can only deduce from the given statement that Putin and America have not been on good terms because President Trump was accused of treason simply because he embraced his Russian counterpart. We cannot draw any general conclusions about the relationship between both the countries. Also, we cannot infer anything about the prior presidents of America from what is given. Therefore, option 3 is the correct answer.
