Read the excerpt from act i of the importance of being earnest.

algernon. in the third place, i know perfectly well whom she will place me next to, to-night. she will place me next mary farquhar, who always flirts with her own husband across the dinner-table. that is not very pleasant. indeed, it is not even decent . . and that sort of thing is enormously on the increase. the amount of women in london who flirt with their own husbands is perfectly scandalous. it looks so bad. it is simply washing one’s clean linen in public. besides, now that i know you to be a confirmed bunburyist i naturally want to talk to you about bunburying.

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.
