Input: Consider Input: Article: Sitting on a chair all day in school can make anyone want to move around. So, more and more teachers are letting students have a ball. By sitting on exercise balls instead of chairs , teachers find students' posture  and attention improve. Dottie Pownall, a fifth-grade teacher in West Virginia, USA, has been using balls as chairs since December 2008. "The students love them", she says. Pownall took a survey  of her students. She found that 80% of the students thought sitting on the balls helped them pay more attention to what they were learning. The teacher, Pisa Witt, felt so strongly about the use of balls as chairs, she started Witt Fitt. This company encourages the use of the balls. And the company educates not only teachers but also students on how to use them. "Our products are used in 24 states, three provinces in Canada, Puerto Rico   and Japan," says Witt, " Research shows that sitting on the balls makes them sit up straighter . You can slouch on a ball," says Witt, "but it feels bad." Because the students are moving, their blood   increases. That carries more oxygen( ) to the brain , so the kids have more energy and can pay attention longer. "Besides, they're fun." says Pownall.

Input: Consider Input: Article: As winter gives way to spring, students feel like taking outdoor activities. However, do remember that accidents can happen, such as the one that happened at Taihu Lake several weeks ago. Four students from Shanghai were killed and several were injured. There were several reasons for the accident, but if the students had worn life jackets, it would have made a big difference. Therefore, it is important to take steps to avoid accidents before going on trips whether on land or water. Here are some steps: Make sure you are physically fit for any activities. You need energy for hiking or boating after a long inactive winter. Research your route  . Check the weather report so you can pack the correct things so that an unexpected downpour or high winds won't destroy your day. If you are visiting a different culture, learn some basic knowledge about what's accepted and what is not. Take plenty of water to prevent your body from losing too much water and be sure to wear the correct footwear to protect your feet. Don't go to faraway areas and never risk going into unknown waters. Going in a group is safer than going alone. If you have to travel by yourself, leave a note of your travel route, telephone number and how you are traveling. So if there's an emergency, people can get in touch with you.

 Options: (A) warn students against traveling alone (B) introduce the topic of the passage (C) show the disadvantages of outdoor activities (D) remind students of the importance of life jackets 
 Asnwer: C

Output: No


Input: Consider Input: Article: A dog found shot in the head and face with a pellet   gun, stuffed in a garbage bag and left to die is recovering from his injuries at an animal clinic in Texas. The bag containing the 3-year-old male mixed breed was discovered tied to a fence in Conroe, Texas, earlier this month. When local residents opened the bag, the dog appeared, took a few steps and fell. Augustyn rushed the dog to an emergency animal clinic, where he was treated for many pellets to the face, eyes, mouth, neck and shoulders. The dog was stabilized, but according to Dr Ron Hendrick, a vet at the Animal Emergency Clinic of Conroe, pellets remain in both eyes and it's unclear whether the dog nicknamed Buck was left blind forever. A Facebook page, Buck Needs Bucks for His Buckshot Injuries, was launched last week by Augustyn. It was created to help pay for the dog's medical bills. The page has attracted nearly 7,000 "likes" and, according to its creator, already more than enough donations to pay for his treatment. "The last 24 hours has been overwhelming for me," Augustyn wrote on the page. "I have gone from not knowing if I would have enough money to pay for Buck's emergency bill to having an unbelievable amount of money to provide the best possible care for Buck's recovery. I have thought long and hard about this today and how I should handle this. The conclusion is that I will open a separate bank account for Buck and all donations will be used for Buck's recovery and necessities." With the help of Facebook, Buck's story quickly sparked international interest. "Buck is now walking," Augustyn says. Police in Montgomery County say they are investigating the incident, and Augustyn says she has been in contact with law enforcement officials about donating a reward for information leading to the arrest of the person who tortured the dog. Sadly, cases like Buck's are not uncommon, particularly in Texas. 
 Question: When Augustyn found the dog, it was   _  . 
 Options: (A) being shot by its owner (B) tied to a fence near an animal clinic (C) in a horrible physical state (D) hiding from its owner inside a bag 
 Asnwer: D


Output: No
