Assume the following statements are true: 1. All state university graduates are scholars. 2. No state university graduates are association members. Which conclusion MUST be true?

  1. All association members are scholars.
  2. Some association members are scholars.
  3. Some scholars are not association members.
  4. None of these conclusions necessarily follows.

Answer

C. Some scholars are not association members.

Solution

All state university graduates are scholars, and none of the state university graduates are association members. So the scholars who are state university graduates are not association members: some scholars are not association members. The other choices may or may not be true, so they do not necessarily follow.
