Final answer:

The mineral on the right likely formed from magma beneath the Earth's surface, cooled slowly, and has larger crystals typical of intrusive rocks like granite. The one on the left, formed from lava on the surface, would have smaller crystals indicating a faster cooling process typical of extrusive rocks like basalt. The statement regarding luster is not directly related to the information given about the formation and cooling of minerals.

Step-by-step explanation:

Based on the provided information, we can make the following conclusions about the minerals in question:

  • The mineral that formed from magma that cooled below the Earth's surface, which cooled gradually and slowly, allowing individual crystals to grow large, suggests that the mineral on the right is likely intrusive and plutonic, such as granite.
  • The mineral on the left that formed from lava would have cooled more quickly on the surface, resulting in smaller crystal sizes, indicative of an extrusive or volcanic rock, such as basalt.
  • If the statement indicates that the mineral on the left has larger crystals than the mineral on the right, this would be contradictory to the general understanding of crystal size relative to the cooling process, hence it would not be a correct statement in this context unless there was an atypical cooling process or the statement refers to an unusual observation.

The statement about shinier luster is not addressed with provided information and luster can vary among minerals, so it is not directly related to their mode of formation or crystal size.
