And here's your Shmoop du jour, brought to you by Galileo.

00:06

He was more than just a poor boy from a poor family.

00:11

Yeah.

00:11

Check out the following passage.

00:13

[ mumbles ]

00:23

All right, and what do we wanna know?

00:25

Well, most of Europa is composed of what?

00:28

And here are the potential answers.

00:31

Okay, well, we can start by asking answer B to stop...

00:33

collaborate, and listen to what we just read in the passage.

00:37

It sounds like ice is only on the surface of Europa

00:40

and not a major part of its composition.

00:43

So we can pencil it in as a maybe for Spring Break. [ chuckles ]

00:46

Answer C seems like a possible answer

00:49

because of the wording of the last sentence of the passage.

00:52

But this sentence is referring to the atmosphere

00:54

rather than the planet itself, so, uh,

00:56

it can blast off.

00:57

So this leaves us with answers A and D.

00:59

We can rule out answer D because the passage

01:01

states that Europa probably has an iron core.

01:05

We assume that they say probably because, uh,

01:07

well, there's a chance it could be marshmallow, as well.

01:09

So this means answer A is our correct answer

01:12

and most of Europa is made of silicate rock.

01:15

Kinda like sand, basically, so, uh, well, you know.

01:18

Rock on, Europa. Rock on.
