Answer 2

Weird questions you got there pal:

1 - doesn't make sense
2 - d.
3 - doesn't make sense
4 - d.

Now go back to your textbook and figure out what exactly they could have meant by #1. #3 still does not make sense (looks like someone messed up order of questions and answers) but you might be able to shed some light on it as well.
Go reaad the textbook before it's too late and get a good night sleep before the exam.
Good luck!
