A parse tree is not generated for q2 because the sentence is not in the language of the grammar, i.e., the goal symbol S does not derive the sentence.

You should write the sentence down on paper and then manually try to construct a parse tree for it. You'll find that it can't be done, and the specific ways in which it fails to be possible should suggest ways that the grammar needs to change in order to make it possible.

For example, here's one problem (not the only one): in the grammar, NNP derives both 'Big' and 'Data' (and nothing else derives either of them), so (roughly speaking) the sentence begins with NNP NNP, and yet S is incapable of deriving a form that starts with NNP NNP.
