You have to look up 2. VERY boring. Thumbs down.
The article says what sublimation is, not "when" and "how", and it doesn't talk about the "major" reservoirs, just two sentences on reservoirs. You are going to have to do a little bit more research on rq 2. RQ 3 is not logically correct.
I could not find 3 or 2 and was boring
