Must Be False Qustions.

PowerScore,

I know somewhere in the book it gives me a reason why I should change Must be False to could be false, but I cannot find it. Can you refresh my memory? Thank you!

Hello Echx73,

Perhaps you mean that Must Be False can be converted to Cannot Be True?

Hope this helps,

To follow up on this, we recommend converting false statements (like must be false) to their equivalent "true" statements (in this case cannot be true) because statements/questions phrased in "true" language tend to be easier to understand and thus answer than statements of falsehood.

It really comes down to familiarity, which, if you'll allow me to just quote directly from Lesson 2 of our Full-length Course, means this: "Most students, unaccustomed to think in terms of falsity, lose valuable time trying to understand the exact meaning of the question. The most efficient way to handle this problem is to always convert from False to True."

So there you have it! It's all about efficiency and consistent comprehension.
