Read the following article and select the best answer. Article: Several weeks ago, a mysterious Christmas card dropped through our mailbox. The envelope was addressed to a man named Raoul, who, I was ly certain, did not live with us. The envelope wasn't sealed, so I opened it. The inside of the card was blank. Ed, my husband, explained that the card was both from and to the newspaper deliveryman. His name was apparently Raoul, and Raoul wanted a holiday tip. We were meant to put a check inside the card and then drop the envelope in the mail. When your services are finished at 4 a.m., you can't simply hang around, like a hotel bellboy expecting a tip. You have to be direct. So I wrote a nice holiday greeting to this man who, in my imagination, fires The New York Times from his bike aimed at our front door, causing more noise with mere newsprint than most people manage with sophisticated black market fireworks. With a start, I realized that perhaps the reason for the 4 a.m. wake-up noise was not ordinary rudeness but carefully executed spite : I had not tipped Raoul in Christmas past. I honestly hadn't realized I was supposed to. This was the first time he'd used the card tactic . So I got out my checkbook. Somewhere along the line, holiday tipping went from an optional thank-you for a year of services to a Mafia-style protection racket . Several days later, I was bringing our garbage bins back when I noticed an envelope taped to one of the lids. The outside of the envelope said MICKEY. It had to be another tip request, this time from our garbage collector. Unlike Raoul, Mickey hadn't enclosed his own Christmas card from me. In a way, I appreciated the directness. "I know you don't care how merry my Christmas is, and that's fine," the gesture said. "I want $30, or I'll 'forget' to empty your garbage bin some hot summer day." I put a check in the envelope and taped it back to the bin. The next morning, Ed noticed that the envelope was gone, though the trash hadn't yet been picked up: "Someone stole Mickey's tip!" Ed was quite certain. He made me call the bank and cancel... Question: Ed's encounter with the recycling team shows that _ . - Ed was desperate to correct his mistake - Ed only wanted to give money to Raoul - Ed was unwilling to tip the truck driver - Ed no longer wanted to give them money
(Answer)
Ed was desperate to correct his mistake

Read the following article and select the best answer. Article: Solar energy for your home is coming. It can help you as a single home owner. It can help the whole country as well. Whether or not solar energy can save your money depends on many things. Where you live is one factor and the type of home you have is another. Things like insulation , present energy costs, and the type of system you buy are added factors. Using solar energy can help save our precious fuel. As you know, our supplies of oil and gas are very limited. There is just not enough on hand to meet all our future energy needs. Sooner or later Mother Nature will say that's all. The only way we can delay hearing those words is by starting to save energy now and by using other sources, like the sun. We won't have to worry about the sun's running out of energy for another several billion years or so. Besides, the sun doesn't offer as many problems as other energy sources. For example, fossil fuel adds to already high pollution levels. With solar energy, we will still need sources of energy, but we won't need as much. That means we can cut down on our pollution problems. With all these good points, why don't we use more solar power? There are many reasons for this. The biggest reason is money. Until now, it was just not practical for a home owner to put in a solar unit. There were cheaper sources of energy. All that is changing now. Solar costs are starting to equal the costs of oil and electricity. Experts say that gas, oil and electricity prices will continue to rise. The demand for electricity is increasing rapidly. But new power plants will use more gas, oil or coal. Already in some places the supply of electricity is being rationed . Solar energy is now in its infancy . It could soon grow to become a major part of our nation's energy supply. Question: What's this passage mainly about? - Something about solar energy and pollution. - Solar energy. - Energy and pollution. - Energy and money.
Solar energy.
