Q6 - Saturn's moon Enceladus has a rocky core

[Laura Damone]

Question Type:
ID the Conclusion

Stimulus Breakdown:
Conclusion: Between the layers of rocky core and icy surface, there must be a lake of liquid water.

Evidence: The Cassini space probe measured density of matter composing the moon. It revealed something denser than ice between the core and the surface. That could only be liquid water.

Answer Anticipation:
Look for an answer that paraphrases the second sentence. That sentence uses the phrase "these two layers." Expect the answer to replace that reference and name the layers explicitly.

Correct answer:
B

Answer choice analysis:
(A) This is background information.

(B) Bingo. Matches our prediction. Paraphrases sentence two.

(C) This is a premise.

(D) This is another premise.

(E) This is yet another premise!

Takeaway/Pattern:
A common form for ID the Conclusion questions is to have the conclusion tucked into the middle of the argument, following either background info or an opposing point!
