Given: x, y, and z are prime numbers and x < y < z
Target question: What is the value of x?
Statement 1: xy is even
This tells us that one of the variables must be 2
Since 2 is the smallest prime number, and since x < y < z, we can conclude that x = 2
Since we can answer the target question with certainty, statement 1 is SUFFICIENT
Statement 2: xz is even
This tells us that one of the variables must be 2
Since 2 is the smallest prime number, and since x < y < z, we can conclude that x = 2
Since we can answer the target question with certainty, statement 2 is SUFFICIENT
Answer: D
