Question

read the section of the \beat the heat\ infographic with the graphic of the cars and clocks. what is the authors purpose in this section? to persuade the reader to purchase a car with air conditioning to inform the reader about how quickly temperatures can rise in cars to entertain the reader about different models of cars

Explanation:

Infographics are often used to convey information. The mention of "clocks" (which could imply time - related temperature rise) along with cars suggests a focus on data (temperature rise over time in cars). There's no indication of a sales pitch (so not persuasion to buy a car) and no elements for entertainment (like humor or stories about car models).

Answer:

to inform the reader about how quickly temperatures can rise in cars
