Answer

Brief Explanations:

The statements about the unknown - mineral's hardness are based on its ability or inability to scratch other minerals. The first idea is valid as being able to scratch a mineral implies it's harder. The second idea is correct because not being able to scratch a mineral means it's not harder. And the third idea is in line with the conclusion in the given text.

Answer:

The unknown mineral is harder than the minerals that it was able to scratch. The unknown mineral is not harder than the mineral that it was not able to scratch. The unknown mineral is a relatively hard mineral.
