Must, should, can, may, might, could, would, will are words that come before the subject in the questions.

Hi, Dmitry. How are you? First of all, it's not needed to put "that": ..."she told me THAT she...". You have to change into "...she told me she..." About the sentence, it depends of the context. But I'd choose the first. Because she has told you about her real situation and you commented it with someone. That is, you are passing an information from someone to other person who wasn't presented at that conversation. You just reported it, you spoke for her. This was my point of view. I hope to have helped you. :) See you!

Normally, "While + subject + verb + ing" or "while + subject + verb" makes connection between two sentences that happen at the same moment. For example: Simple Past: - My cellphone rang while I was taking a shower. - She left home while he was sleeping. Simple Present: - I study English while my brother sleeps. Simple Present Continuous: - I'm doing this while he is helping me with that. Well, I hope to have helped you. :) See you around!

According to Tony, it's exactly that. Really, "what year are we in" sound natural and more comprehensive. If you say it putting "I", "they", "she/he" or "you", it will sound like if these people were living in other planet or period of time (this is impossible hahaha). I hope to have helped you, too. See you around!
