Can someone please answer this question?

At any stage in a proceeding, before or during trial, a judge may have to determine whether to let a jury decide a particular issue. In making this determination, the judge considers whether the issue is a question of LAW or a question of FACT. If the question is one of fact, it should be decided by the jury at trial. If the question is one of law, the judge may decide it without affording the parties the opportunity to present evidence and witnesses to the jury.
