Read the following article and answer the question. Article: Tom and his best friend Rob were out of school for the summer. They had been swimming, gone to the movies, played video games, and even built a castle out of some old cardboard boxes. But today they were so bored. "At least we would have something to do." Tom thought for a while and suggested, "Let's make some popcorn and lemonade and sell it outside." The boys went to the kitchen and asked Tom's mom if she would help them make some lemonade while they popped the popcorn. Tom's mom got the lemons from the refrigerator and also a small amount of sugar. She mixed up the lemonade while the boys started popping the popcorn. Tom and Rob got a small table from the garage and set it up near the sidewalk. They made a red sign telling everyone that popcorn and lemonade was for sale. The boys sat for about ten minutes before they got their first sale. Mrs. Jenkins, one of their neighbors, was walking her dog. "It's so hot today." "I sure can use a drink," she said. Soon the boys were busy handing out popcorn to Mr. Baker. He was walking down the street sending the mail. "I need a break," he said. "Walking all over the neighborhood gave me an appetite." The boys had only three popcorn bags left and enough lemonade for three more cups. "Wow, I didn't think the popcorn and lemonade would sell that fast. We made six dollars," said Tom. "If we get bored again before school starts, we can try selling more lemonade with cookies next time," laughed Rob. Question: What did Tom suggest? Answer:
OPTIONS:
- Swimming with their friends.
- Buying some sugar and cookies.
- Making some popcorn and lemonade.
- Going to the movies and playing games.

Read the following article and answer the question. Article: Prana was a beautiful dog, whose name means "breath of life". Although he died several years ago, I can still remember the days we spent together and what he has taught me about love. I have two apple trees in the garden. Prana loved apples. When he went outside, he'd catch an apple and take it into the house to eat later. The apples had been on the ground and were often dirty so I wasn't always happy that Prana had brought them into the house. It was an autumn day in America, but it was very cold. A big snow fell and we had not done anything for its coming. On that special day, Prana went outside and I watched him through the window. I noticed that he was madly digging holes and bringing the apples to the ground so they could be seen above the snow. I did not know why he was doing this. He seemed to want to do something special. When I called him back, he had his usual one apple in his mouth. About five minutes later, I looked outside. The garden was completely covered with birds. Prana had dug up all those apples for his bird friends to eat. He knew that they wouldn't have stored enough food for the coming winter! Question: On the snowy day, Prana _ . Answer:
OPTIONS:
- ate up all the apples
- dug holes to put the apples in them
- brought the apples under the snow to the ground
- left the house and died
brought the apples under the snow to the ground
