Hello Penuel,

I have three questions for you:

1. Where did you get those exercises?

2. Are you absolutely sure you have transposed them all correctly?

3. What do you think the most appropriate answers might be?

Hello Esl Expert!

I am confused as in most of the sentences the choices above mentioned are seem to me all to be right like in 1), 2), 5) 6) and 7).
In 3) i think the right choice is a) and in 4) - e).

These exercises i got from test sample which provides our college and i do transpose them correctly, i just have omitted those choices which i thought might not be right. And here they are without any omissions.

2)... I use your dictionary?
a) can b) may c) shall d) might e) must

3) ... you address me in that tone?

4) You ... laugh if you ... but I was sure I ...
a) may/will/should b)can/may/might c)should/will/can d)could/will/should e) may/could/should

5)When we went into the house, we ... smell burning.
