Read this excerpt from a passage. "Her purchase got me thinking about the early days of online shopping, when people were anxious about ordering
merchandise from the Internet. What if the items never arrived? Was putting all my personal information online safe? Should I
really disclose my credit card information to some unknown entity? Is this online company legitimate? And last but not least,
who would buy something without seeing it first? But my grandmother's transaction made it clear: online shopping has
become as commonplace as brushing your teeth.
"As millions of consumers flock to online shopping, I wondered how and why people make the decision to shop online or
in person. To get a better understanding of how e-commerce has affected our buying decisions, I decided to gain some insight
from friends and family. The reviews were varied but insightful."
Which of the following subjects will be compared in the rest of the passage?
o delivery to a home and delivery to a store
O shopping online and shopping in person
O online shopping and brushing your teeth
O prices of items online and prices of items in stores

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.
