Which revision would improve the clarity of the first sentence regarding car shopping online?

The revision that improves the clarity of the first sentence is the one that explicitly links the ability to quickly find a car with the use of the internet in a straightforward manner. By stating, "Thanks to the internet, I was able to quickly find a car," the sentence clearly emphasizes the cause (the internet) and the effect (finding a car quickly). This direct connection enhances understanding for the reader, as it presents the information in a logical sequence.

Additionally, the phrasing in this revision is simple and concise, which helps maintain readability. In contrast, other choices may introduce unnecessary complexities or convoluted phrasing that could obscure the intended message. For example, some options place less emphasis on the role of the internet in the car search or use less direct language, making them less effective in conveying the same clarity.
