I am currently studying for the JLPT N2, and I am confused about the answer for this particular practice question:
I put 始まっている最中に as the answer, but my textbook tells me that the correct answer is 始まろうとしている。
My thought process behind this answer was that 最中に is usually followed by an act of interrupting the task at hand, and I interpreted this situation as リンさん interrupting the starting of the meeting.
Is there a specific reason to why 始まろうとしているとき is the correct answer?
I’m really confused because 始まっている最中に (in the middle of starting) and 始まろうとしているとき (when about to start) sound really similar to me.
