Final answer:
Option D, suggesting that owners of the car dealership may appear untrustworthy, connects the concerns about hybrid car performance with dealer reputations, enhancing the cohesion between the paragraphs.
Step-by-step explanation:
The question pertains to which sentence could be added to better connect the last two paragraphs of a passage about hybrid cars and the trustworthiness of car dealers. After reviewing the given options and the context provided by the passage, the most suitable sentence to connect the paragraphs would be Option D: "The owners of the car dealership seemed a bit untrustworthy; Dawn should have followed her instincts." This option suggests a link between the qualities of the vehicles discussed earlier and the trustworthiness of the sellers, which aligns with the remarks about dealership reputations and the risks associated with cheaper prices from less reputable sources. It creates a clear cause-effect relationship that is inferred but not explicitly stated in the text.
