Thanks for your question. False used in this context does not necessarily mean that the answer is wrong. It instead means that, given the passage at issue, a given answer choice could or must be false.Here is an example. Letâ€™s say that the question prompt states: There is a gum ball machine with only red and blue gum balls. When one puts a coin in the machine, a single gum ball comes out.

If the question stem is which of the following COULD be false, and one of the possible answers is

If you put a coin in the machine, you have a 50/50 chance of getting a red or blue gum ball.

Then we have an example of an answer that COULD, but not must, be false. The reason for this is that although we know the two gum ball colors, we donâ€™t know the ratio of gum balls in the machine. Therefore, while it could be true that you have a 50/50 chance, it also could be false (if, for example, there were 9 blue gum balls and 1 red one.)

But it is not the case that this answer must be false, because we donâ€™t know the actual ratio of gum balls.

I hope this helps! Please let us know if you have further questions.

It helps! ThanksEva on January 4, 2019

It's there're any practice further on the prep course to apply the True V. False lesson ? If there is any, please guide me to the section.Ravi on January 5, 2019

Hey there,Regarding whether there is any additional practice in the prep course

to apply the content from the True v. False lesson:

Yes, there is. If you go back to main curriculum page, you'll see that

there are 'Must Be True' and 'Cannot Be Trus' sections. Both of these

sections have extensive video lessons as well as many examples where

you can continue to apply what you've learned.

Does this help? Let us know if you have any other questions!

conditional logic) are very helpful.

S - >N

Above is the general diagram that denotes a conditional statement. The

"S" stands for sufficient and the "N" stands for necessary. The

sufficient condition is the condition that, if met, triggers the

necessary condition. The necessary condition is the condition that

must occur if the necessary condition is met.

The contrapositive of S - >N is

/N - >/S

What does this mean? It's a deduction we can make based on S - >N

If the necessary condition MUST occur if the sufficient condition is

met, then what happens if the necessary condition doesn't occur? Well,

if it doesn't occur, then the sufficient condition MUST NOT occur.

/N - >/S
