Question

question 20
part a: what is the meaning of “molten” in paragraph 2?
a. liquid
b. solid
c. weak
d. strong

Explanation:

To determine the meaning of "molten" in paragraph 22, we analyze the context. The text says "the molten rock (called magma) can then flow upward or even erupt from a volcano onto the Earth’s surface" and "When magma cools rapidly...crystals grow from the molten liquid". The description of it flowing and being a liquid, along with the contrast to when it cools (forming crystals from the liquid), indicates "molten" refers to a liquid state. Option A is "liquid", which matches this context. Options B (solid), C (weak), and D (strong) do not fit the description of a substance that can flow and is the source of crystals when cooled.

Answer:

A. liquid
