1,Today's football match has been...due to the bad weather. It will be played next Saturday instead.
A.Cancel
B.Postpone
2,...pollution control measures are expensive, many industries hesitate to adopt them.
A.However
B.Because
I chose B for both but the keys not.

Yes, the answer keys appear to be wrong (both are OK for #1 if cast in the past tense.)

Yes sir. They should both have been in past tense. Why can cancelled be accepted in such a sentence?

Strictly speaking it ought to be 'postponed' but often 'cancelled' is used instead. In a test, I would think that only 'postponed' would be accepted.
