BAIRD: Buildings in the United States are responsible for 30% of greenhouse gas emissions across the country. If you want to do something about climate change, your home is among the most important places to look.
CHARLES: Maybe it's hard to imagine a house releasing greenhouse gases just sitting there, but think about your daily routine. You stumble out of bed in the morning, turn on the lights, turn up the thermostat, take a shower, and make some coffee or toast. The heat and the hot water may come from a furnace or a water heater that burn gas. They release carbon dioxide straight into the air, other kinds of pollution too actually. The lights and the coffee maker and the computer run on electricity, and that comes from power plants, most of which are still burning coal and gas. You can actually look at your electric bill and calculate those emissions.

Option 3: "To give examples of how a house can produce greenhouse gases."
Explanation: This option is correct because the speaker uses daily routines to illustrate specific ways in which homes contribute to greenhouse gas emissions. By detailing activities like turning on lights and using appliances, he effectively shows how these actions lead to pollution, aligning with the main idea of the text.
Option 1: "To tell the listeners how he started his life every day."
Explanation: This option is incorrect because the speaker does not focus on his personal daily routine but rather uses it as an example to illustrate a broader point about greenhouse gas emissions. The mention of daily routines serves a different purpose than simply sharing personal habits.
Option 2: "To list the appliances responsible for 30% gas emissions across the country."
Explanation: This option is incorrect as it misinterprets the speaker's intent. While the appliances mentioned contribute to emissions, the focus is not on listing them as responsible for the 30% figure, but rather on demonstrating how everyday activities lead to greenhouse gas production.
Option 4: "To ask people to get rid of the electric devices mentioned."
Explanation: This option is incorrect because the speaker does not advocate for eliminating electric devices. Instead, he highlights their role in emissions to raise awareness about climate change, not to suggest their removal.
