Cannot be true

If the statement says "Each of the following statements must be true EXCEPT ", why isn't ''cannot be true" the logical opposite of "must be true"?

@lsatprep remember, the logical opposite is the minimum required to disprove a statement.

For this reason, the logical opposite of "must be true" is "not necessarily true."

Similarly, the logical opposite of "hot" is not "cold," as you might think.

The logical opposite of "hot" is "not hot." Room temperature would be sufficient to disprove the statement that something is hot.
