PrepTest 155 - Section 2 - Question 6

Show summary

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.”
