Can you help be better understand why the answers to these two questions are correct? The answers just don’t make sense to me.
The correct answers are A and F for 21 and
A and D for 22.
Thank you!
Firstly apply the pairing strategy for the questions. For q21, the first part of the sentence says that it would save the aquifer by, so by here is support. So the terms should be similar to harmless hence A and F(innocuous and benign means harmless).
