Assume the following statements are true: 1. No endemic species are protected animals. 2. Some primates are endemic species. Which conclusion MUST be true?

  1. No protected animals are primates.
  2. Some primates are protected animals.
  3. Some primates are not protected animals.
  4. None of these conclusions necessarily follows.

Answer

C. Some primates are not protected animals.

Solution

Some primates are endemic species, and none of the endemic species are protected animals. So the primates who are endemic species cannot be protected animals: some primates are not protected animals. The other choices may or may not be true, so they do not necessarily follow.
