Should Subjective challenge questions have answer space equal to the correct answer space?

Question

It helps a lot in Subjective challenge questions as we can many times find out answer just by checking the answer space. Example suppose question has two possible answers (hello,by). Now if the answer space is of 2 blanks the answer has to be "by".

Answer 1

In my opinion sololearn should provide with a long blank space for answer so that the above advantage will no longer be a factor in challenges.
