Suppose that I want to explain why we select the students using specific metrics. I've written down:
if we choose the students indiscriminately, the fairness goes under the question.
if we choose the students indiscriminately, the fairness is questionable.
Selecting the students indiscriminately makes the fairness questionable.
Question: Would you please provide me with better sentences and phrases?
Personally, I prefer to use phrases similar to "go + under + question". Such phrases are very common in my native language (Persian). Also, for me, It is interesting to see whether English-spoken people use such phrases or not.
Thanks in advance.
