| To answer a question like that, first arrange it normally, S then V, like 'the test is on which chapters?'
^Obviously that is awkward, but when you rearrange, you keep the S/V the same, so you know you want 'is'. A choice may be what sunshadow said. And always watch out for prepositions at the end.
