Getting answers to questions in learning situations is important.
I highly suggest some relaxation on the requirement.
There are a couple of reasons why this is suggested:
There is always something the teacher will not be able to explain that you just have to get. The habit of filling in the gaps correctly is one that will need to be developed if needing all answers to progress is needed. This is not to say that there are not good questions. No, questions are at the root of learning. This is to say that there needs to be a correct balance in the asking of questions.
Sometimes the questions are legitimate and the teacher/materials need to clarify/be clarified. Other times the questions flow from incorrect habits of the student and waste valuable time where real progress could be made. The more one is able to tell the difference, the better the questions will be. If one is not sure about how good the skill set is here, hold off on the questions especially if that feeling of nitpickiness is present.
