Aromantic hero must be mysterious, melancholy, rebellious, passionate, and isolated.
a. true
b. false

I think true, but that is just based on fictional characters i have read about- 

Peeta Mellark is one of them- in the books, he isn't too rebellious, but he is definitely described as being isolated, passionate, and melancholic.   

Gale Hawthorne is another- He is rebellious, passionate for what he believes in and towards Katniss. a lot of the time in the books he seems melancholic, not very isolated, but i think you get the point. 

China plays a major role in population and china is also a well developed country
