Dear teachers ,,my questions in this style will go on if you don't mind.....THANKS FOR NOW.
1-- According to what you have typed, none of the answers are possible. Any is a possible answer.
2-- Answer B (how) is correct; the answer sheet is wrong.
3-- Both A and C are grammatically possible; C makes more logical/physiological sense.
4-- The correct answer is A; D is wrong.

I suggest that you throw away this test book and get a better one.
Your English appears to be better than that of the people who constructed this test.
There are too many mistakes in these test items to rely on the source they came from. Throw it out!

Students: We have free audio pronunciation exercises.
Thank you,,

but I will give the assesment test back brochure where I got.
