The way to deal with underspecified questions is to note the ambiguity, seek clarification if possible, and then if you still need an answer and can’t get clarification, assume a probability distribution for each missing detail. Producing an answer is always possible, but the more ambiguities you had to do this for, the less useful the answer will be.
a [...] is white: 0.1
a car is [...]: 0.1
a [...] is [...]: 0.05
I wouldn’t be willing to actually use those probabilities for much of anything, because as soon as I had a use for the answer, I’d surely also have found out what the actual question was, and be able to produce a much better answer.
