In a recently held parent-teacher meeting, the teachers had very few complaints about Ravi. After all, Ravi was a hardworking and kind student. Incidentally, almost all of Ravi's friends at school were hardworking and kind too. But the teachers drew attention to Ravi's complete lack of interest in sports. The teachers believed that, along with some of his friends who showed similar disinterest in sports, Ravi needed to engage in some sports for his overall development.

Based only on the information provided above, which one of the following statements can be logically inferred with certainty?

  • A.All of Ravi's friends are hardworking and kind.
  • B.No one who is not a friend of Ravi is hardworking and kind.
  • C.None of Ravi's friends are interested in sports.
  • D.Some of Ravi's friends are hardworking and kind.

Answer: D

The statement that follows with certainty is Some of Ravi's friends are hardworking and kind.

The passage says that almost all of Ravi's friends were hardworking and kind. If almost all of them are, then at least some of them are, so this statement is guaranteed.

'All of Ravi's friends' overstates 'almost all'. The passage says nothing about people who are not Ravi's friends, so the claim that none of them is hardworking and kind cannot be inferred. And only some of his friends showed a similar disinterest in sports, so 'none of Ravi's friends are interested in sports' goes beyond the information given.
