Answer:

Pick any answer between 5.5 and 7. If you have 6 choose it.

Explanation:

Quartz has a hardness of 7.

The steel ball is 5.5

The mineral must be between these two values. Written mathematically

5.5 < x < 7

So pick any value that is between 5.5 and 7.  The other choices would be valuable.
