­­OFFICIAL EXPLANATION QUESTION #1

The correct answer follows from the passage, though it may not be stated explicitly. Choice (A) is not implied. Although researchers probably hope to stem the occurrence of diabetes, the passage speaks only of combating the disease’s impact. There is also no suggestion in the passage of the hope, expressed in choice (B), of creating an artificial system. Choice (C) is too extreme. The passage doesn’t imply a “standstill” absent “complete” understanding of the proteins. The wording in choice (D) is dense, but it’s also broad enough to follow from the passage. Researchers may well use their understanding of the hormonal cues monitored by the proteins to develop the treatments mentioned in the final sentence of the passage. Indeed, (D) is the correct response. Finally, (E) runs counter to the passage. The researchers hope to understand how to help the relay system work, not how to cut it off. You can eliminate (E) confidently.
