Hi,
1)The two owners were divided__ the issue of whether to hire a new secretary or not
a) on
b) by
c) into
The answer is a but I don't know why it's not b A and B are both possible, although A is more idiomatic. 'Over' is probably the best answer of all.
2)" Yes I know", Claira said
or "Yes I know", said Claira
? Both are fine. You need a period at the end, and a comma after 'yes'.
3)In the SAT, are we allowed to work on the previous section? ( I mean, we are to do section 9 but come back to section 8 or 7 to check the answer), is it possible?I don't know.
Best wishes, Clive
