s |
> |

Choices:
You are given a range of values for s, and you are asked if s is positive. That is not much to go on, so go to the statements.
You are given a range of values for s, and you are asked if s is positive. That is not much to go on, so go to the statements.
| Statement (1): |
s |
× |
s |
> |
4 |
if |
s |
= |
2 |
or if |
s |
= |
-2. |
Since |
s |
could be either |
| positive or negative, Statement (1) is not sufficient to answer the question. |
| Statement (2): In order for |
1 |
÷ |
s |
to be greater than |
1 |
÷ |
3, |
s |
must be |
| positive. So Statement (2) by itself is sufficient. |
