<p>** UPDATE: EXPLANATION FOUND. **</p>
<p>Here's the question reprinted: How many integers in the range of 20<x<30 have two different prime numbers as their only multiples?</p>
<p>A) Zero
B) One
C) Two
D) Three
E) Four</p>
<p>My answer is B)Two, i.e. 21 and 22.</p>
<p>Correct answer is D)Three, what is the third integer?</p>
<p>Please note, 1 is neither prime nor composite, so 23, 27 and 29 are dis-regarded. 25 is the product of the same primes. 24, 26 have non-prime multiples.</p>
<p>*EDIT: I forgot 26. 13 x 2. Lame :| *</p>
