Francine is researching air pollution in major US cities. She wants to understand the negative effects of air pollution in those cities and has conducted some research. After beginning her draft, she has concluded that she has enough information to start, but she needs to narrow down the information that she is using in her paper to best support her topic. Which source would most likely support her research on air pollution in major US cities? A. A government website with data on air pollution throughout the United States B. A documentary on the benefits of living in cities with high air pollution levels C. A brochure geared for Americans on how to help reduce air pollution D.

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.

The economic boom of the roaring twenties coincided with, and was partly fueled by a) the end of wwii b) the birth of consumer culture c) the beginning of the coolidge presidency d) the end of prohibition
