Bhai, I am not trying to mock you here, but please give it a serious thought and try to solve this problem yourself. If you aren't serious in your classworks then you are just wasting your time in US.
Save your time and go back...Or smart up and start learning and paying serious attention.

Hi,
  I see those are really basic questions you are asking (that too multiple choice). If you cannot solve these problems then you are in a big problem. I just graduated from engineering and what I suggest you is try to do these by yourself. You might save an hour or two now and make $20 working in gs instead. But you are losing a lot in a long run. I used to do that too and I totally regret now. So start working hard (not in gs but in classes).

thanks for the suggestion guys...I have already tried these question and I read the book too but can't find a solution so I needed help...about the multiple choice I have done it but just need to confirm it as it's for my finals. The first question is my main concern cause I am not able to solve it.

Bange...thanks for the reply. Already the just answer...Just answer EXPERT has many wrong answer so don't want to go with it. Just a case, you said for 7 it's e but as per the EXPERT it's a and b.
For 1, I didn't just want to copy and paste so was trying to understand how it's done so that I don't have to work in the Gas Station :)
