Read the following excerpt from "the cask of amontillado" and answer question.

the thousand injuries of fortunato i had borne as i best could, but when he ventured upon insult i vowed revenge. you, who so well know the nature of my soul, will not suppose, however, that gave utterance to a threat. at length i would be avenged; this was a point definitely, settled --but the very definitiveness with which it was resolved precluded the idea of risk. i must not only punish, but punish with impunity. a wrong is unredressed when retribution overtakes its redresser. it is equally unredressed when the avenger fails to make himself felt as such to him who has done the wrong.

it must be understood that neither by word nor deed had i given fortunato cause to doubt my good will. i continued, as was my in to smile in his face, and he did not perceive that my smile now was at the thought of his immolation.

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.
