Hello Khai Minh. Please try to answer them yourself first and tell us why you chose those answers; then we will check your results.
Yes, i do it now.
1> i choose A. because of " the +...+in+...."
2> i choose C, i don't think " impulses" is a verb.
3> i choose D, just a guess, i don't know why.
4> i choose A, since B and D is not correct, but C maybe right.
5> i choose C, it must have" in Boston",and i think "on a street" is better than " in a street"
kind regards,
Khai Minh
Site Hint: Check out our list of pronunciation videos.
Good work, Khai Minh.

1. No; B is the answer-- 'oil' is a non-specific uncountable noun here.

2. Right. 'Send' is the main verb.

3. Good guess. 'Chain' as an adjective should be singular, and 'restaurants' as the subject should be plural to agree with the verb 'have'.

4. Right. A is a correct idiomatic phrase. C would be correct if it read: 'on the whole'.

5. You're right, I suppose, because they are speaking of an American city, but this is a poor question-- AmE uses 'on Beacon Street', but BrE uses 'in Beacon Street'.
Thanks, now i understand.

2.to send sensations

3.chain restaurant

4.On a whole

5.on beaconstreet in boston
