5. The new ambassador is well-informed about current affairs. (wide)
6. They were brought up in a conventional, middle-class way. (theirs)
7. It was Derek who pointed the mistake out to me. (attention)
8. They were on the point of canceling the match when the opposition arrived (call)
9. One essay is just as bad as the other. (choose)

10.There is less chance that Olsen will become champion after his recent defeat (blow)
---> His recent defeat is a blow to his chance of becoming champion.

Task II: Rewrite the origin sentence beginning with the word given:

or ---> Bill had arranged someone to repair the wireless.

7. It was Derek who paid attention to my mistakes.
8. They were about to call off the match when the oppositon arrived.
