Answer:
The answer is 2,200ºC
Explanation:
I took the assignment for Edge, I don't think I can send the image because it might pick up on that and get reported, sorry!
The only other rationale that I have is that it's boiling because the graph shows that it's at a constant temperature/rate at 2,200ºC for quite a while. Typically when something boils, it stays at that constant rate of boiling, unless you turn the temperature up or it's finally able to peak..?

The answer is glucose.
Hope it helps!
