Pergunta 1: A riverside neighborhood planted 200 trees along its bank. Two summers later, sensors showed that air beside the trees was about 2 °C cooler than on nearby bare streets. What is the main idea?

The passage reports a measured temperature difference after planting, so the safest main idea is the local link it describes, not a universal claim.

The sale price is 80% of the original price, so divide by 0.80: 40,000 / 0.80 = 50,000 pesos.

x = 2 and x = 3

Factor the quadratic as (x - 2)(x - 3) = 0, so x = 2 or x = 3.
