@Tony,Substitution questions are often the most challenging ones for students and are best skipped if you are short on time. One way to approach the substitution question is to see if the new constraint results in the same inference as the original one.

This game tells us that:

(1) T cannot be mentioned in chapter 1 and

(2) T must be mentioned before W, and there must be exactly two chapters between them.

This rule results in the following sequence:

T __ __ W

We can infer that since there must be at least 3 clues before W, W cannot be #1, #2 or #3 and since T cannot be #1, W cannot be #4 either. W thus must be #5, #6 and #7 and T must be #2, #3, or #4.

The question asks us which rule would have the same effect as rule (1). We can see that the inference from rule (1) is that W cannot be #4. Thus, the answer choice (B) will have the same effect as rule (1).

I am not sure if there is a specific video lesson on substitution questions, but please feel free to reach out to our support team and provide this feedback. They can be reached by tapping "support" from the left menu or by calling 855.483.7862 ext. 2 Monday-Friday 9am-6pm PT.
