AThe extensive network of Remaining source text redacted.
Why choice A matches the stem
Correct. Argument or Facts:
Argument
Valid or Flawed:
Flawed
Question Type:
Main Point
Stimulus Summary:
The "most likely" explanation for a phenomenon is given. The author then pivots to what some others believe, before presenting a "more likely" explanation for a phenomenon related to the first one, based on another premise supporting it.
Answer Anticipation:
The argument structure in this argument is relatively complex, with a conclusion in the first statement ("most likely" being the key indicator), a shift to a full counterpoint argument, and then another conclusion ("more likely" being the key indicator) and its premise.
Since there are two conclusions, we need to see which supports the other. Here, it makes more sense that the rebuttal to the counterpoint (uniformity is more likely indicative of diameter) supports the more general conclusion that the overall network was most likely created through erosion.
Answer Explanation:
This answer reflects the more general opinion about the likely creation of the tracks in Malta and is thus the main point.
Key Takeaway:
Language of comparative likelihood is generally an indicator of a conclusion.
Also, when there are two conclusions, the more general one tends to be the main point, though this trend isn't as strong as some others on the exam. -
BSome researchers have suggested Remaining source text redacted.
Why choice B is not credited
Incorrect. This answer reflects the opposing point. In a Main Point question, an answer that states the opinion of a specified other group (here, some researchers) is almost always a counterpoint, and thus wrong. -
CSome researchers cite the Remaining source text redacted.
Why choice C is not credited
Incorrect. This answer is a premise offered by the opposing viewpoint. In a Main Point question, an answer that states evidence presented by a specified other group (here, some researchers) is almost always a counterpoint, and thus wrong. -
DThe uniformity of depth Remaining source text redacted.
Why choice D is not credited
Incorrect. This answer reflects the subsidiary conclusion, and it would thus be a tempting trap answer. However, this specific conclusion supports the more general one presented in the first sentence. -
EThe ancient tracks on Remaining source text redacted.
Why choice E is not credited
Incorrect. This answer is the premise the author offers for the subsidiary conclusion.
