Could be true vs Must be true

Hi, I seem to be having some difficulty with deciding between could be true answers and finding which of them must be true. Is there any tips or tricks you could give for eliminating could be true answers choices to narrow down to the must be true answer? Thanks, Payton

Hi @paytonklatt, thanks for your post.

What you want to internal is the logical opposite of "could be true," which is "cannot be true." Thus, on a "could be true" question, the four wrong answers "cannot be true"--that is, they are inconsistent with / contradicted by the text.

By contrast, the logical opposite of "must be true" is just "not necessarily true." This means that on a "must be true" question, the four wrong answer are "not necessarily true"--they may be consistent with or inconsistent with the text, but they are not directly supported by the text itself.

Does that help? Please let us know if you have any additional questions.

Why are we not diagramming using the S&N or quantifeir rules. Are there questions to which these rules apply and dont?
