Some factories that burn coal produce smoke with harmful chemicals, such as sulfur. Scrubbers are devices that are attached to the smokestacks to reduce the amount of sulfur put into the atmosphere. To evaluate the effectiveness of these devices, what data would need to be collected?

• The percentage of sulfur contained, on average, in a certain amount of coal

• The amount of coal a factory burns each year, and how much sulfur it emits

• The increase, over time, in the use of scrubbers by factories that burn coal

• The amount of sulfur emitted by a smokestack before and after the scrubber is attached

Spix’s macaw is an endangered species of bird native to Brazil. The population of the bird has declined over the past 30 years. During this same period, much of the Brazilian rainforest habitat of the bird has been lost due to logging. What data would best support the claim that logging is a likely cause of the decline in the population of Spix’s macaw?

• The trees harvested by logging are not those that are usually the home to this bird.

• This bird is a popular pet and has been bred successfully in captivity.

• The population of this bird was relatively constant before logging began.

• The land cleared by logging is often taken over by farmers for growing crops.
