Solving Scrambled Paragraphs

Scrambled paragraphs are some of the trickiest problems on the SHSAT. The scrambled paragraph section in the Barron’s SHSAT book gives you a pretty good idea of what to look for in these problems. I will not try to replicate that full lesson here. The purpose of this post is to give an idea of the thought process you should go through when you’re solving scrambled paragraphs. We will do two examples: paragraphs 1 and 2 from Form A of the 2015-2016 Department of Education SHSAT handbook.

If / then questions part 2

In part 1 we learned how to solve basic if/then questions. A few key points: Put all statements into if/then form. The contrapositive of a true if/then must also be true. The converse and inverse do not have to be true and are often wrong answer choices. Now we will learn some techniques for dealing with trickier questions where you are given more than one if/then.

The Chain Rule

When we have two if/then statements, sometimes we can connect them. For example, suppose these two statements are true:

If I go to Roma’s restaurant, then I get pizza. If I get pizza, then I get a soda.

This is a chain of events: when I go to Roma’s, I get pizza, and when I get pizza I also get a soda. So whenever I go to Roma’s I end up getting a soda! We can get a new if/then by skipping over the middle step: If I go to Roma’s restaurant, then I get a soda. This must be true!

If / then questions part 1

On the SHSAT, you may see a logical reasoning question like this:

q) Suppose the following statement is true: If it is Monday, then Bob goes to the park. Which of the following must also be true?

A) If it is not Monday, then Bob does not go to the park

B) If Bob goes to the park, then it is Monday

C) Bob’s favorite place is the park

D) If Bob doesn’t go to the park, then it is not Monday

E) Bob doesn’t like going to the beach
