Teacher: Given a premise as input, generate a hypothesis as output that follows the premise based on the following rules: (i) The hypothesis should be derived from the premise. (ii)  The hypothesis must not contain any information that is not in the premise. (iii) The hypothesis should not contradict or have a suggestion that is negative to the premise.
Teacher: Now, understand the problem? If you are still confused, see the following example:
All ten guys that proved to boast were divorcing.
Solution: There are exactly ten guys that proved to boast.
Reason: The hypothesis is a positive example because it is derived from the premise and does not contain any other outside information. Both of them mention ten guys who were boasting.

Now, solve this instance: Have all four waiters that were boring Paul telephoned?
Student:
There are exactly four waiters that were boring Paul.
