Step 1: Understanding the Concept:
This is a vocabulary-in-context question. We must determine the meaning of "coeval with" based on the sentence and the overall argument of the passage.
Step 2: Detailed Explanation:
The passage argues that human modification of the environment is not a recent phenomenon but an ancient one, dating back to Mesopotamia. The fifth sentence reinforces this point by stating that this modification ("It") is "coeval with the origins of writing." The author is establishing a temporal link, suggesting that human modification of nature has been happening for as long as human civilization (as marked by writing) has existed. Therefore, "coeval with" means existing or originating during the same time period.
Analyzing the Options:
(A) influenced by: This suggests a causal relationship, which is not the primary meaning here. The point is about timing, not cause.
(B) older than: This contradicts the intended meaning of occurring at the same time.
(C) coincident with: This means occurring at or during the same time. This is a perfect synonym for "coeval with."
(D) unimpeded by: This means not obstructed by, which is irrelevant to the context of time.
(E) similar to: This suggests a resemblance, but the relationship described is temporal, not comparative.
Step 3: Final Answer:
"Coincident with" best captures the meaning of "coeval with," which is used to indicate that two things originated or existed at the same time.
