Question

based on genetic evidence, archaeologists have generally agreed that reindeer domestication began in the eleventh century ce. however, since uncovering fragments of a 2,000 - year - old reindeer training harness in northern siberia, may have begun much earlier. which choice completes the text so that it conforms to the conventions of standard english? choose 1 answer: a researcher robert losey has argued that domestication b researcher robert loseys argument is that domestication c domestication, researcher robert losey has argued, d the argument researcher robert losey has made is that domestication

Explanation:

To determine the correct answer, we analyze the context and grammar. The first part of the text presents the general agreement about reindeer domestication timing, and then introduces new evidence (the 2,000 - year - old harness) that leads to a new claim about domestication beginning earlier. We need a clause that shows a researcher making an argument about domestication.

• Option A: "researcher Robert Losey has argued that domestication" fits the context. The structure "has argued that" introduces the claim that domestication may have begun earlier, and the subject - verb agreement and logical flow are correct.
• Option B: "researcher Robert Losey’s argument is that domestication" is more wordy and less natural in the flow of the sentence. The original text structure is better served by an active - voice construction of someone arguing, rather than a possessive - noun - based construction of an argument being.
• Option C: "domestication, researcher Robert Losey has argued," misplaces the subject and disrupts the logical flow. The comma after "domestication" makes the sentence structure confusing as it separates the subject of the claim from the argument.
• Option D: "the argument researcher Robert Losey has made is that domestication" is overly wordy and awkward. It uses a more convoluted structure to express the idea compared to the straightforward "has argued that" in Option A.

Answer:

A. researcher Robert Losey has argued that domestication
