The OG answer is A but the answer shud be B.
This is why I think it should be B.
1) Is 'one of its main problems has been' is correct
OR 'one of its main problems have been' is correct? I
think the former should be correct because of one.
2) Recently extended slump : adverb + adjective +
noun should be correct? if not how do we know when it
will act as a phrase and when it will acr as
Adv+Adj+noun combination?
3) Why is this in past perfect? The slump is still on
and has started in the past. I believe it should be
present perfect.
If I am right on all the 3 points above the answer
should be B and not A. Please help.
Thanks,
