Which type of question is this?

Assumption

Question 4

Does an assumption question need a conclusion?

Answer 4

An assumption question necessarily needs to have a conclusion in the passage or the question stem.

(It’s very rare for an inference question to have a conclusion in the passage or the question stem.)

Question 5

If 6/x(x+1)>1

What condition must be fulfilled so that the inequality holds?

Answer 5

We’re told that 6/(product) > 1 so the denominator must be LESS than 6. That way 6/(less than 6) will be > 1. So we’re really just looking for a product that’s less than 6.
