Remove q_a_pairs.csv and the reference to it, replace it with the answerable_questions API call.
See #131 to see how answerable_questions api is used to populate dataframe.

@richagadgil does #131 take care of this issue?

[richagadgil]

No, this issue is requesting @cameron-toy to replace his use of the q_a_pairs.csv with an API call to answerable_questions when possible. He can use my code as a reference because it does the same thing :)

[richagadgil]

Then hopefully we can remove q_a_pairs.csv from the api repo

@richagadgil This has been resolved right?
