Question

read the introduction
i support the purchase of streetlights for our community. my young sons enjoy riding their skateboards in the street in the evening, but darkness makes this a reckless undertaking, even with reflective gear. further, our family has contributed dues to the neighborhood association for nearly ten years, and no structural improvements have been made during this time. the association has money saved for projects such as these, and it is time to use these funds to promote safety.
what is the authors purpose?
○ to inform readers about skateboarding safety
○ to inform readers about neighborhood dues
○ to persuade readers to support an investment
○ to persuade readers to save their money

Explanation:

The author starts by stating support for purchasing streetlights, gives reasons (skateboarding safety at night, lack of improvements despite dues, available funds), aiming to convince readers to support investing in streetlights. The first option is about informing on skateboarding safety (not main purpose), second about neighborhood dues (not main), fourth about saving money (opposite of using funds for streetlights). So the author’s purpose is to persuade readers to support the investment.

Answer:

to persuade readers to support an investment
