Kudos for the right answer and explanation
The question asks "Then which of the following
cannot be the value of y-z? "
So, if we find answer choice that CAN BE a value of y-z, we can ELIMINATE it.
A. 3. If y = 1 and z = -2, then y-z = 3. ELIMINATE A
B. 2.75. If y = 0.75 and z = -2, then y-z = 2.75. ELIMINATE B
C. 2.5. If y = 0.5 and z = -2, then y-z = 2.5. ELIMINATE C
D. 2 . If y = 0 and z = -2, then y-z = 2. ELIMINATE D
E. 1.5 Must be the correct answer
Answer: E
