Can the positive integer a be written as the sum of 2 different prime numbers?
(1) a is greater than 5.
(2) a + 1 is even.
Kaplan's answer: E
My answer: B
Correct me if I am wrong here, but doesn't the question say "CAN", not "DOES"?
The way I see it, B tells me that variable a is odd, which means that 2 + 3 = 5. This tells me that (2) CAN be true.
However, Kaplan says the following:
"Statement (2) says that a is odd, which is insufficient because some odd numbers are the sum of two different primes and others are not. For example, 5 is the sum of two different primes (3 + 2), but 11 is not. Eliminate (B)."
Seems to me that Kaplan's question refers to CAN and the explanation/answer points to DOES.
Am I reading this incorrectly or is Kaplan sloppy with their language here?
