Guys, I get stuck on those two questions, and i need your help!

Game 2, Q6-11

Fu, Gunsel, Jackson, Kowalski, Lee, Mayer, and ORdoveza are the only applicants being considered for some positions at a nonprofit organization. Only applicants who are interviewed will be hired. The hiring process must meet the following constraints:

[using abbreviations here]:

if G is interviewd, J is interviewed.

if J is interviewd, L is interviewed.

F is interviewd.

Fu is not hired, unless K is interviewed.

K is not hired, unless M is interviewed.

if M is hired, and L is intervieweed, Ordoveza is hired.

My problems lie with Q9 and 11:

9. if G and five other applicants are the only applicants interviewed, and if exactly three applicants are hired, then which one of the following could be an accurate list of the applicants hired?

A. F, L, M

B. F, K, W

C. K, L, O

D. G, J, M

E. G, J, L

11. if O is not interviewed, and if exactly four applicants are hired, then which one of the following must be false?

A. L is hired

B. M is hired

C. J is interviewed

D. K is interviewed

E. G is interviewed

Thanks a lot!
