Question

lunar terrain
the light areas of the moon are known as the highlands. the dark features, called
maria (latin for seas), are impact basins that were filled with lava between 4.2 and 1.2
billion years ago. these light and dark areas represent rocks of different composition
and ages, which provide evidence for how the early crust may have crystallized from a
lunar magma ocean. the craters themselves, which have been preserved for billions
of years, provide an impact history for the moon and other bodies in the inner solar
system
what is the central idea from the excerpt of the article
\what is the moon made of?\
parts of the moon were filled with lava billions of years ago.
the craters on the moon are artificial structures that were created by
ancient civilizations.
the different colorations of the moon provide information about how it was
formed.

Explanation:

The text discusses lunar terrain, including highlands and maria (dark areas filled with lava). It mentions that light and dark areas (different rock compositions/ages) give evidence about the Moon's early crust (from a lunar magma ocean). The craters provide an impact history. The key is that the moon's colorations (light - dark areas) offer info on its formation. The first option is just a detail (lava filling parts). The second option (craters as artificial) is wrong as the text says craters are natural (preserved impact history).

Answer:

The different colorations of the moon provide information about how it was formed.
