Archaeologist: The extensive network of ancient tracks on the island of Malta was most likely created through erosion caused by the passage of wheeled vehicles. Some researchers have suggested that the tracks were in fact manually cut to facilitate the passage of carts, citing the uniformity in track depth. However, this uniformity is more likely indicative of wheel diameter: Routes were utilized until tracks eroded to a depth that made vehicle passage impossible.

Summarize Argument: Counter-Position
The author proposes a different explanation for the origin of the ancient tracks on Malta. Some researchers think the tracks were intentionally cut to make it easier for carts to use them. The researchers’ evidence is that the track depth is all the same. The author acknowledges that the track depth is all the same, but thinks this just indicates the wheel diameter, which eroded the tracks to the same depth. The author’s theory that the uniform track depth indicates wheel diameter is used to support the idea that the network of tracks results from erosion from use by carts.

Identify Conclusion
The conclusion is the author’s explanation for the origin of the tracks: “The extensive network of ancient tracks on the island of Malta was most likely created through erosion caused by the passage of wheeled vehicles.”

A
The extensive network of ancient tracks on the island of Malta was most likely created through erosion caused by the passage of wheeled vehicles.
This is a verbatim restatement of the conclusion.
B
Some researchers have suggested that the ancient tracks on the island of Malta were in fact manually cut to facilitate the passage of carts.
This is the researchers’ view, which the author believes is likely wrong.
C
Some researchers cite the uniformity of the depth of the ancient tracks on the island of Malta to support the suggestion that they were manually cut.
This describes the support used by the researchers. The author reaches a different conclusion based on a different interpretation of that support.
D
The uniformity of depth of the ancient tracks on the island of Malta is probably indicative of the wheel diameter of the carts that passed over them.
This is an intermediate conclusion supported by the part after the colon. The author uses the theory that uniform track depth shows wheel diameter to help support the broader explanation that the tracks are caused by erosion from use by the carts.
E
The ancient tracks on the island of Malta were utilized until they eroded to a depth that made vehicle passage impossible.
This is a premise. It supports the intermediate conclusion that the uniform track depth shows wheel diameter. The theory that uniform track depth shows wheel diameter is used to support the broader explanation in the first sentence.
