对on the first floor提问,是Where is there an office?
还是Where is the office?
Different reference books have different answers, what on earth is the most appropriate answer?
the same as lucy12345678. since the questioner ask the location of an office, he must know something about the office, such as its name, its function, and so forth. it's a specific office. while the first answer refers to an office that the replier doesn't know what kind of the "an office" is.
so the answer should be "The office is on the first floor." rather than "There is an office on the first floor".
However, the question is There is an office on the first floor? not the officer,
so, in my view, the most appropriate question should be "Where is the office?"
Because, if you don't specify the "the office", there are so many offices on earth, it is also very common for you to ask for the place of some office, while not a office.
Is my answer correct???
