Why are in the quiz factory only the languages swift and c available?

Question

Quiz factory (no html?)

Answer 1

Because there are enough html quizzes and sololearn needs more swift and c quizes.

Answer 2

I see that makes sense thanks.

But I see very often the same quizzes in the html language (thats why I know mostly the right answers).

Therefore in my opinion there arent enough html quizzes either.

Is it official that sl thinks there are enough html squizzes?
