I had a test yesterday and 3 questions of the grammar part confused me a bit.
the first two are:
We were in such a bad financial situation that we had difficulties ............. our bills each month. a) that pay / b) for paying / c) paying / d) to pay
and similarly :
His plays are so elaborate and difficult to understand that even the critics find difficulty......them. a) explain / b) explaining / c) to explain / d) with explain
well I chose the gerund form of the verb for both questions ("paying" and "explaining") and my question here is whether there is any difference between them or not?! why is one of them "difficulties"(plural) and the other one "difficulty"(singular) ?!
the other question is:
Britain's trade position has been ............ weakened by inflation.
among the answer choices there were "very" and "very much" ... and I chose very much but still don't know what's the difference in here. and if there really is.. what is it?!
