Is my explanation correct for why locations CAN be the direct object of motion verbs? Both in English and Japanese, it is commonly agreed that LOCATIONS CANNOT MOVE, but instead we (as in ANIMATE BEINGS) move. But, in Japanese it ISN'T necessary to have a word like "through" to describe the direct object of motion verbs, because LOCATIONS ARE STATIONARY, and it's just a superfluous step. I'm paraphrasing this from "Tae Kim's Guide to Learning Japanese: Japanese Grammar Guide". She writes, "Unlike the direct object we're familiar with in English, places can also be the direct object of motion verbs such as あるく　and　はしる. Since the motion verb is done to the location, the concept of direct object is the same in Japanese."

どのくにがおもしろい？ Is this correct ”どのくにがおもしろい？”

Is it possible to have a question with the particle は in it, and respond with が to it? I'm trying to come up with basic rules for my Japanese grammar notes, but I'm not too sure how to write it for this situation. I have a feeling it's not possible to ask question that has the particle は in it, and have the responder reply with the particle が.

The my explanation why は can't be used in this sentence, correct? Why は can't be used, and が has to be used. EX: A: だれ　が　がく？ B's response would be "who is who a student?" and the ”だれ”would become the new topic of conversation.
