Notice the word NOT is added to the if-clause, not the then-clause. Otherwise, we would make the mistaken assumption that both schools cannot be on the list together, which is not necessarily true—at least on the GMAT or LSAT.
Hidden if-then statements
Many if-then statements on the test are hidden because they do not use if orthen. Instead, they use words like all, any, when, must and so on. Consider this example:
All Chinese students are diligent.
Translation: If you are a Chinese student, then you are diligent. (I truly hope so!!)
The trick here is that all means if.
There are also words that mean then. Here is another example:
Reading SDCAR’s posts on CR requires good understanding of English.
Translation: If you can read SDCAR’s posts on CR, then you have good understanding of English. (Pat yourself on the back, please!!)
Here are more words you can use to find hidden if-then statements:
If: All, always, any, each, every, in order to, invariably, no, none, things that, those who, to, when.
Then: Depends on, essential, must, necessary, needs, only, only if, only when, prerequisite, requires.
Unless (if not): Except, until, without.
No
When you see no at the beginning of a sentence, change no to if and negate the other clause, which is your then clause. Example:
No one who has a cold should go outside. (No X is Y.)
Translation: If you have a cold, then you should NOT go outside. (If X, then NOT Y.)
Most, some, and not all
Most means more than half. Most could be all.
Some means at least one. Some = Many. Some could be most, could be all.
Not all means some did not. Not all could be none.
