Here is a sentence:
Before we can examine the implications of neuroscience for criminal law, we must address two more fundamental questions: Why do we punish criminals at all? and How severely should we punish them?
I understand that question marks normally terminate a sentence, and so the following word should normally be capitalised. In this case, I have a list of two questions within the same sentence, so it seems that the "and" after the first question mark should not be capitalised (since the first question mark does not terminate the sentence). The first letter of each question is capitalised to indicate where the question begins.
The sentence seems right to me, but it's a bit unusual, so I thought I would ask for others' opinion.
