1# when talking about this/that/these/such+Noun(ig. cars), should the Noun be consistant with its atandance(the atandance need to be 'cars' rather than 'car'?) in number?
what is "atandance"? do you mean "antecedent"? (i'll assume that's the case for the sake of the following discussion)
i don't understand this question - it seems to be the same as question #2, below.
if you're literally talking about
the same noun, then this question is probably outside the scope of anything you're actually going to see on the test - if it's the same noun, then there isn't much of a reason to repeat it.
2# when talking about this/that/these/such+Noun(ig. cars), should the Noun be consistant with its atandance(not the same Noun but the Noun of same catalog, ig. automobile) in number--in this context, this predator vs. wolves?
apparently not, since the correct answer to this problem has "wolves" and "this predator".
3# if a Noun is function as adj to modify another Noun, can we use it/they to refer the adj Noun? in another words, in this context of 'wolf population', can we use it to refer to wolf ? if not, is such/this wolf ok?
no. in the phrase "wolf population",
wolf is actually an adjective, not a noun. you can't use a pronoun to stand for an adjective.
you can't say "such a wolf" or "this wolf" either; those constructions imply that you actually have some particular wolf in mind.
