I originally chose E, but after reading, one thing that should rule E out immediately is the fact that the AC is reffering to the "way a child learns best" whereas Dana's argument only mentions "a child's accustomed style of learning". Aside from the other reasons that E is incorrect, it should be noted that Dana does not explicitly agree with E. Perhaps she thinks that her proposed method should be used despite the way that the child learns. Who knows.

This question also appears in the curriculum as a causation question-- so anyone who has gone through all of the videos will have already come across it. Thank you!

I agree! Was very disappointed to see that a drill I took used a question from the 70s...now I feel like that entire prep test is ruined.
