Does this question feel kind of ambiguous to you or is it just me?
I thought of it as the lowest score of 2 students in the class which will be quite straightforward 0 and 1 (as at least one student got each possibility) and its less than 4 so A.
But the solution talked about the remaining 9 students whos scores are unknown.
Can we know the question is talking about the remaining by focusing on the work “could” or is this question framed kinda weird and on the GRE it will be more explicitly mentioned?
Thanks for the help!
