Would you expect to find a rock sample containing andalusite, sillimanite, kyanite, corundum, and quartz?

a) Yes, because they all belong to the same mineral family.
b) No, because they belong to different mineral groups.
c) Yes, because they share similar crystal structures.
d) No, because their formation conditions are mutually exclusive.

Final answer:

No, because the minerals belong to different mineral groups and have different formation conditions.

Step-by-step explanation:

No, you would not expect to find a rock sample containing andalusite, sillimanite, kyanite, corundum, and quartz. These minerals belong to different mineral groups and have different formation conditions. Andalusite, sillimanite, and kyanite are polymorphs, meaning they have the same composition but different crystal structures. They are typically found in medium-pressure terranes resulting from continent-continent collision. Corundum and quartz have different compositions and crystal structures, and are found in different rock types. Therefore, these minerals are not commonly found together in the same rock sample.
