Re: Geometry #21

There's clearly a best answer. I didn't mean to raise it as a grading issue. It is, rather, a quality issue.
I am concerned that this is yet again a poorly written question. They've chosen what reads like universal language, but intended that it apply to a particular example.
And this is in a geometry course, the primary place in secondary mathematics where the distinctions between "all" and "some" and between "always," "sometimes," and "never" are taught and reinforced.
