zhanbo · Answer

The answer is  (A)

(1) At least one of the integers is neither positive nor negative. 
Meaning one is 0
the product is 0
SUFFICIENT

(2) At least one of the integers is prime. 
Meaning one is 2
Product can be 0 X 2 = 0
OR
2 X 4 = 8
INSUFFICIENT

IMO A

What is the product of a certain pair of consecutive even integers?

(1) At least one of the integers is neither positive nor negative.
0 is neither positive nor negative but 0 is an even integer
=> product of any number with 0 = 0
 Sufficient

(2) At least one of the integers is prime.
=> 2 is one of the integers being multiplied
but nothing for the range or the start and end values are given
 Not Sufficient

What is the product of a certain pair of consecutive even integers?

(1) At least one of the integers is neither positive nor negative.
(2) At least one of the integers is prime.

statement 1: we must have one integer as 0 so product is definitely 0 so statement 1 is sufficinet

statement 2 : lets take 0 , 2 we have product =0 lets take 2 and 4 product is 8 so not suffiocient

so answer is a)

BIDJI23 · Answer

--> According to A, it means that one element is 0.
So we can conclude about the product

-->According to B, it means that one element is 2 (only even prime number). But is it 2-4 or 2-0? Because there are 2 answers, we go straight to...

Push A

rocky620 · Answer

(1) At least one of the integers is neither positive nor negative.
so one number is 0, and the product will always be 0.

Sufficient

(2) At least one of the integers is prime.
So one number is 2.
Product can be 0 or 8.

Insufficient

IMO Option A

Green2k1 · Answer

Correct Answer A

What is the product of a certain pair of consecutive even integers?

(1) At least one of the integers is neither positive nor negative.
 Means one of the integers is 0
The product will be 0
-Sufficient

(2) At least one of the integers is prime.
 - Means one of the integers is 2
-others could be 0, 4 
- product will be different
- not sufficient

MakSha · Answer

Both the integers are consecutive even integers.

From the first statement, one of the numbers must be 0. since it is the only integer that is neither positive nor negative. thus, the product will be 0.  Sufficient .

From the second statement, one of the numbers must be prime, i.e. 2. Now, another number can be either 0 or 4. thus product can be 0 or 8.  Insufficient .

IMO option A is the answer .

manasi05 · Answer

We have to find the product of certain pair of consecutive even integers.
So our even integer pairs could be x and x+2 or x-2 and x

Statement 1
This statement tells us that at least one of the integers is neither positive nor negative
and the only even integer which is neither positive nor negative is 0
so x = 0
so the pair of integers could be 
-2, 0 or 0, 2
The product of either of the pairs will be 0
Hence Sufficient

Statement 2
At least one of the integers is prime
2 is the only even integer which is prime
So the pair of integers could be
0, 2 or 2, 4
The product of the pair will give the value 0 or 8
We have 2 values for the product of a certain pair of consecutive even integers.
Hence No Sufficient

So the answer will be A

KANNUPRIYA17 · Answer

(1) At least one of the integers is neither positive nor negative.
(2) At least one of the integers is prime

\From 1 we know an even integer which is neither positive or negative is 0. Therefore any number multiplied by 0 is 0.
Sufficient
From 2 we know the only even prime no is 2. So consecutive even number to 2 is 0 or 4. So product will be either 0 or 8
Not sufficient.

IMO A.
