While researching a topic, a student has taken the following notes: - The Mohs scale of mineral hardness is a ten-point scale that orders minerals by hardness based on their ability to scratch other minerals. - Minerals with larger numbers are harder than minerals with smaller numbers and can leave visible scratches on them. - Minerals with smaller numbers are softer than minerals with larger numbers and cannot leave visible scratches on them. - The mineral gypsum has a Mohs scale number of 2. - The mineral fluorite has a Mohs scale number of 4. - The mineral topaz has a Mohs scale number of 8.
The student wants to compare the hardness of gypsum and topaz. Which choice most effectively uses relevant information from the notes to accomplish this goal?
Topaz can leave visible scratches on gypsum, which means that topaz is harder than gypsum.
A
The Mohs scale of mineral hardness can be used to order fluorite, gypsum, and topaz by their ability to scratch other minerals.
B
A mineral with a Mohs number of 4, like fluorite, is harder than one with a Mohs number of 2, like gypsum.
C
Topaz can leave visible scratches on fluorite, which is why topaz has a higher number than fluorite on the Mohs scale of mineral hardness.
D
