Answer 1

Nothing can be concluded about the other characters if it is only given that Peter starts laughing when Jack sleeps, but no information is provided about when Peter stops laughing.

If we assume that Peter will laugh the entire time that Jack is asleep, then the appropriate conclusion would be that Jack is not asleep. Nothing can be concluded about Jill, as there may be other things that make Jill cry.

Thus, the best answer is B.

@flick very correct... I answered the same in the other thread (he asked the question twice).

Answer 3

The real answer is a: Jack is not sleeping but Jill is crying. This question I've found in a programming test and I know for sure that the answer is a but I want to know why

Do you have the link to the question? Option a cannot be right. Check out my response in the other thread.
