If it is not within the confnes of the field (meaning it is not within view of the umpire), isn't this kind of a "if a tree falls in the forest..." kind of question?
(But, then, what do we expect from NFHS test question writers?)
Or, maybe "if a tree falls in a copse ..."
BTW, since the definition of "copse" is "a small group of trees", isn't a "copse of trees", then, "a small group of trees of trees"?
