Which language would you learn

From Italki 

If all the languages in the world were proportionately represented by 100 people at a party:

17 would speak Chinese    6 would speak Spanish    5 would speak English

4 would speak Hindi    3 would speak Bengali    2 would speak Russian   and 2 would speak Japanese.

Without a fellow speaker of their native language to talk to at the party the other 55 would just dance awkwardly.
