PrepTest 155 - Section 2 - Question 6

Hide analysis

Saturn’s moon Enceladus has a rocky core and an icy surface. ███████ █████ ███ ███████ █████ ████ ██ █ ████ ██ ██████ ██████ ███ ███████ █████ █████ ███ ████ ██ ███████ ███ ███████ ██ ██████ █████████ ██████████ █████ ████████████ ████████ █████████ ██████ ████ ███ ███████ ███ ████ ███ ███████ ██ ██████████ ███ ████ █████ ████ ██ ██████ ██████

Summarize Argument

The author concludes that there must be a lake of liquid water between Enceladus’s rocky core and icy surface. This is because a space probe discovered something denser than ice between the core and the surface, and that denser substance can only be liquid water.

Identify Conclusion

The conclusion is the assertion that there’s a lake of liquid water between Enceladus’s rocky core and icy surface: “Between these two layers, there must be a lake of liquid water.”

Which one of the following ████ ██████████ █████████ ███ ███████ ██████████ █████ ██ ███ █████████

a

Saturn’s moon Enceladus ███ █ █████ ████ ███ ██ ███ ████████

This is context. The author’s conclusion concerns what must be in between those two layers.

0%
b

There must be █ ████ ██ ██████ █████ ███████ ███ █████ ████ ███ ███ ███ ███████ ██ ██████████

This is a restatement of the second sentence, which is the conclusion.

93%
c

The Cassini space █████ ███ ████ ██ ███████ ███ ███████ ██ ██████████

This is part of the support. The author concludes that there must be a lake of liquid water based on what this probe found.

0%
d

Density measurements reveal █████████ ██████ ████ ███ ███████ ███ ████ ███ ███████ ██ ██████████

This is part of the support. The author concludes that there must be a lake of liquid water based on these measurements.

1%
e

Anything denser than ███ ███████ ███ ████ ███ ███████ ██ █████████ █████ ████ ██ ██ ██████ ██████

This is part of the support. Because the denser substance could only be water, the author concludes that a lake of liquid water must exist between the rocky core and icy surface.
