Which source would best provide a context for the type of research Alex is seeking? O a scholarly article written by a leading Environmental Law professor on the topic of agricultural runoff and its effects on the
surrounding environment
a lawsuit brought by a small rural town against a major agricultural corporation, which links agricultural pollutants to an increase in
chronic illness among the town's residents
O a report detailing the results of a University of Arizona study on the link between agricultural pollutants and the levels of carbon
dioxide and methane released into the atmosphere

the environment over the course of five years

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.
