Question

Which best supports the choice from Part A?


The crust is closest to the surface, which means it is the hottest.


The mantle contains minerals, which means it is solid.


The outer core is liquid metal, which means it is very hot.


The inner core is solid metal, which means it has magnetic properties.

I don’t have Part A, so I can’t pick the exact best support yet. Could you paste the choice you made in Part A?

If you can’t, here’s how to match them:

- If Part A claimed the mantle is solid → pick: “The mantle contains minerals, which means it is solid.”
- If Part A claimed the outer core produces Earth’s magnetic field or causes convection → pick: “The outer core is liquid metal, which means it is very hot.” (The key supportive fact is that the outer core is liquid metal; its motion generates the magnetic field.)
- If Part A claimed the inner core is solid metal → pick: “The inner core is solid metal, which means it has magnetic properties.” (Note: this statement is misleading—Earth’s magnetic field mainly comes from the liquid outer core, not the solid inner core.)
- If Part A claimed the crust is the hottest layer → none of these are good support (the crust is actually the coolest).

Tell me the Part A answer and I’ll choose the best support.
