1.) Methane (CH,) is a greenhouse gas, with the potential to raise global temperatures 20 times faster than equal amounts of carbon dioxide. Currently, methane makes up approximately 10% of greenhouse gas emissions in the United States. In order to reduce the rate of global temperature increase, it is a more important to decrease carbon dioxide emissions than methane emissions b more important to decrease methane emissions than carbon dioxide emissions c equally important to decrease carbon dioxide emissions and methane emissions d. irrelevant whether methane or carbon dioxide emissions increase or decrease

In order to reduce the rate of global temperature increase, it is a more important to decrease carbon dioxide emissions than methane emissions b more important to decrease methane emissions than carbon dioxide emissions c equally important to decrease carbon dioxide emissions and methane emissions d. irrelevant whether methane or carbon dioxide emissions increase or decrease 2) Which of the following solutions might most directly help prevent the oceans from becoming increasingly acidic? a. exploring the oceans for new oil fields b replacing the bicycles used for transportation in many parts of the world c. using solar energy instead of coal to produce clectricity d. using trucks instead of trains to transport oil 3) Midges of the family Ceratopogonidae are considered nuisance pests by campers, who call them "no-see-ums." Some species of the midges transmit discase through their saliva, while others serve to pollinate certain plant species. Which of the following would be a disadvantage to humans resulting from the extinction of these midges? a the eradication of Bluetongue virus, a discase of sheep and cattle carried by midges h the extinction of Theobroma cacao (the cocoa tree). Which is pollinated by midges c the eradication of parasitic skin discases carried by midges d. the proliferation of Elaphrus cupreus, a ground beetle that preys on midges

Questions 4 and 5 are based on the passage below. Acid rain is a form of precipitation caused by the release of sulfur dioxide and nitrogen oxide into the atmosphere. Acid rain is comprised of a mixture of wet and dry deposition. If the acidic chemicals in the air blow into places with wet weather, the acids fall to the ground in the form o rain or fog, affecting plant and animal life. In drier climates, the acidic chemicals mix into dust o smoke, which will then fall to the ground or on trees or buildings. These deposits are later washed off by rainstorms. The addition of water to these chemicals makes the resulting mixture more acidic. The acidic chemicals themselves form as a byproduct of burning fossil fuels, such as coal, oil, diesel, and gasoline. Acid rain alters the chemical balance of lakes, affecting aquatic life. It also alters the chemical balance of soil, harming plant life. In addition, it damages buildings and statues. 4) Which of the following technologies can help reduce acid rain? a.a diesel locomotive, which burns diesel fuel to produce energy that is used to turn the wheels b. an electric power plant that burns coal to heat water and produce steam to drive turbines, which power the generator Ca refinery, which purifies metals, petroleum, and other substances into a more useful förm d. a catalytic converter, a device in the exhaust system of a vehicle that reduces harmful emissions from the engine 5) Which of the following would reduce the amount of ecological damage caused by acid rain? a replacing a coal-burning power plant with a sola-farm b.coating metal and stone statues in silicone C.constructing buildings from materials resistant to erosion d. using diesel fuel instead of gasoline in automobiles
