Three Incorrect Answer Traps

            The stimuli for Strengthen and Weaken questions tend to be
                  similar: both often contain faulty reasoning.
The same type of wrong answer traps appear in Strengthen as in Weaken
questions:
1. Opposite Answers. These answers do the exact opposite of what is
needed—they weaken the argument. Because of their direct relation
to the conclusion they are tempting, despite the fact that they result in
consequences opposite of those intended.
2. Shell Game Answers. Remember, a Shell Game occurs when an idea
or concept is raised in the stimulus and then a very similar idea
appears in the answer choice, but the idea is changed just enough to
be incorrect but still attractive. In Strengthen questions, the Shell
Game is usually used to support a conclusion that is similar to, but
slightly different from, the one presented in the stimulus.
3. Out of Scope Answers. These answers simply miss the point of the
argument and support issues that are either unrelated to the argument
or tangential to the argument.
These three answer types are not the only ways an answer choice can be
attractively incorrect, but they appear frequently enough that you should be
familiar with each form.
