How does the structure of this italian sonnet by petrarch support its theme? those eyes, 'neath which my passionate rapture rose, the arms, hands, feet, the beauty that erewhile could my own soul from its own self beguile, and in a separate world of dreams enclose, the hair's bright tresses, full of golden glows, and the soft lightning of the angelic smile that changed this earth to some celestial isle, are now but dust, poor dust, that nothing knows. and yet i live! myself i grieve and scorn, left dark without the light i loved in vain, adrift in tempest on a bark forlorn; dead is the source of all my amorous strain, dry is the channel of my thoughts outworn, and my sad harp can sound but notes of pain. the structure of an octave and a sestet confirm that the poet is longing for love. the overall structure conveys the theme of humanism, which considers worldly love to be superior. the octave displays a musical quality, while the sestet has a jarring quality that shows conflict. the octave builds an idea about love, while the sestet comments on that idea.

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.
