ugh. 9/10 was incorrect at abstruse, the only word which i had to take a guess.
The correct answer:
D The salesman began his pitch with a lot of abstruse technical jargon that his customers would never understand.
Your answer:
A I think you're being deliberately abstruse when you refuse to answer my questions.
Abstruse means difficult to understand.
But it rhymes with obtuse, which means dull-witted or slow to perceive something, so people sometimes mix them up.
I avoided D since I thought "obscure" was the correct word in the sentence, but meh.
