"Are the chips on the plate?"

Translation: Aia ke kipi ma ke pā?

[IPPSl411]

My answer: Aie ke kipi ma ke pa mea 'ai? For an earlier translation of "Didn't you order me a plate?" I said: 'A'ole 'oe i 'oka i pa, na'u? and it was wrong because I didn't say "pa mea 'ai na'u?" So which is it?

Another sentence was as follows:

Are the extra chips on the plate? = Aia ke kipi keu ma ke pā mea ʻai?

Now, for Are the chips on the plate? I put: Aia ke kipi ma ke pā mea ʻai? and was marked wrong.

I just want to make sure this is a case of DL overlooking a valid answer; or am I missing something? (Not unlikely, as Iʻve done many times before.)
