[Q]: Article: He was driving home one evening, on a country road. Work, in this small community, was as slow as his broken Pontiac. But he never quit looking. Since the factory closed, he'd been unemployed. And with winter approaching, the cold days had finally hit home. It was a lonely road. Very few people had a reason to be on it, unless they were leaving. Most of his friends had left. But he stayed on. After all, he had his root here. It was getting dark, and snow was coming down. He'd better get a move on. Suddenly he saw an old lady on the roadside and obviously needed help. So he pulled up in front of her Mercedes and got out. She was worried. No one had stopped to help for the last hour or so. Was he going to hurt her? He looked poor, hungry, and ... dangerous. He could see that she was frightened, standing out there in the cold. He said, "I'm here to help you, Ma'am. Why don't you wait in the car where it's warm? By the way, my name is Joe." The car had a flat tire. Joe crawled under the car and soon he was able to change the tire. But he had to get dirty and his hands hurt. As he was turning the screws ,she rolled down her window and began talking to him and said she couldn't thank him enough for coming to her aid.  She asked him how much she owed him. Any amount would have been alright with her. She had already imagined all the terrible things that could have happened had he not stopped. Joe never thought twice about the money. This was simply helping someone in need, and God knows there were plenty who had lent him a hand before. He had lived his whole life that way, and it never occurred to him to act any other way. He told her that if she really wanted to pay him back, the next time she saw someone who needed help, she could give that person the assistance they needed, and Joe added "... and think of me." A few miles down the road the lady saw a small cafe. She went in to grab a bite to eat, and take the chill off. It was a dirty-looking restaurant. Outside were two old gas pumps. The whole scene was unfamiliar to her. The waitress came over and brought a clean towel to wipe her wet hair. She had a sweet smile, one that even being on her feet for the whole day couldn't erase. The lady noticed that the waitress was nearly eight months pregnant, but she never let the strain and aches change her attitude. The old lady wondered how someone who had so little could be so giving to a stranger. Then she remembered Joe. After the lady finished her meal, she handed the waitress a $100 bill. When the waitress came back with the change, she found the lady was gone and something written on a napkin. Reading the note, there were tears in her eyes. It said, "You owe me nothing. I've been there too. Someone once helped me out, like I'm helping you. If you really want to pay me back, don't let the chain of love end with you. That night when she got home from work, she was thinking about the money and what the lady had written. With the baby due soon, life would be harder. She knew how worried her husband was, and as he lay sleeping next to her, she gave him a soft kiss and whispered soft, "Everything's gonna be alright; I love you, Joe."

[Q]: Article: Lopburi is around 150 kilometers north of Bangkok, the capital of Thailand. What make Lopburi famous are its more than 2,000 monkeys who live in the middle of the city.

[Q]: Article: At night, bats fly through the air, catching hundreds of insects and other small animals. But during the day, they hardly move at all. Instead, bats pass the time hanging upside down from a secret spot. There are a couple of reasons why bats rest this way. First of all, it puts them in a position for takeoff. Unlike birds, bats can't fly into the air from the ground. Their wings don't produce enough lift to take off from a dead stop, and their hind legs are so small and underdeveloped that they can't run to build up the necessary takeoff speed. Instead, they use their front claws to climb to a high spot, and then fall into flight. During the hours when most enemies are active, bats gather where few animals would think to look and most can't reach. This allows them to disappear from the world until night comes again. There's also little competition for these resting spots, as other flying animals don't have the ability to hang upside down. Bats have a unique physiological adaptation that lets them hang around this way without using any energy. For you to hold your fist around an object tight, you contract  several muscles in your arm, which are connected to your fingers by tendons ;as one muscle contracts, it pulls a tendon, which pulls one of your fingers closed. A bat's talons  close in the same way, except that their tendons are connected only to the upper body, not to a muscle. To hang upside down, a bat pulls its claws open with other muscles. To get the talons to take hold of the surface, the bat simply lets its body relax. The weight of the upper body pulls down on the tendons connected to the talons, causing them to hold tight. Therefore, the bat doesn't have to do anything to hang upside down. 
 Question: Bats hang upside down because  _  . 
 Options: (A) they haven't developed a pair of strong claws (B) they can't start to fly from the ground directly (C) they have no hind legs to support their body (D) they can't find quiet places to stay during the day
[A]:
B
