Read the excerpt from "The Day the Gulls Went Crazy". Clearly, "bird brains" are more complicated than we think. And perhaps, we humans aren't so smart after all. That's something to think about next time you watch a bird. And if you see some gulls, think twice before you disturb them. They just might remember your face. And as Larry can tell you, they dive-bomb with missile-like accuracy.

Which statement best explains how the passage supports the author's purpose?

A. The purpose is to entertain; the author jokes that gulls will take revenge if people bother them.

C. The purpose is to persuade; the author wants readers to appreciate that gulls are more intelligent than people realize.

D. The purpose is to question; the author doubts gulls can really memorize what people look like.

3one of the biggest impacts a building has on earth is the energy it uses. currently, most of the world’s energy comes from burning fossil fuels. these fuels are dirty and when they are burned they pollute the air and water. one way to burn fewer fossil fuels is to reduce the amount of electricity a building has to use. passive solar heating, which uses heat from the sun, reduces the amount of fossil fuel used to heat buildings. passive solar heating requires a south-facing wall made of glass. when sunlight shines through the wall, it is collected and used to warm the building. another way green buildings reduce their electricity use is to install other energy sources. for example, some green buildings use panels that turn energy from the sun into useable electricity. which is the best summary of paragraph 3? a) fossil fuels are dirty and pollute the air and water. most of the world's energy comes from these fuels. b) the biggest problem of buildings is that they use fuel that is dirty for heating. they need to do something to be more energy efficient. c) panels that turn energy from the sun into electricity and passive solar heating can stop the burning of fossil fuels which pollute air and water. d) since fossil fuels are dirty and pollute the air and water, other technologies that pollute less and produce energy have been developed like solar energy and green buildings.
