I recall one time that the answers were four B's in a row.

I found it strange as it seemed like the questions were built around for this answer only. I had little time left as class was about to end, so I went with my gut and kept the four B's.

I later discovered that I had failed the test. I asked my teacher about it and her response was:

"It was a fucking essay question. Not a multiple choice. Holy shit, I can see why you failed middle school and your father and I have to homeschool you."

Lesson learned.
