user: I'm taking a test and have to guess the right answer to the question after the article. Article: When you watch TV programs about wild animals, it is surprising to see how an antelope can escape a lion's attack. In the wilderness, everyone has a stunt. Even plants have their own ways of fighting off enemies. Over millions of years of evolution, plants have developed a unique defence system. Chemicals are wildly used for survival. By making their leaves, flowers, roots and fruits distasteful or poisonous  to enemies, plants can fight back. One such plant is the Golden Wattle tree. The British scientist David Cameron has found when an animal eats the tree's leaves, the amount of poison increases in the other leaves. "It's like the damaged leaves telephoning the others telling them to fight together against the enemy, " he said. The tree also sends defence messages to neighboring plants by giving out a special smell. Golden Wattle trees in the surrounding 45 meters will get the message and produce more poison within 10 minutes. Now, if an enemy eats too many of the trees' leaves, it will die. Every species of plant or tree is good at the production of a particular set of chemicals. A _ that can safely eat the leaves of one tree may be poisoned by its neighbor. In this way, plants have developed not only individual defence system, but also shared it with others. This makes it impossible for a single animal to destroy even a small area of forest. Question: Which of the following can be the best title of the passage? Options: A: Plants Fight back with Poisons B: Plants Can Kill Animals C: Animals and Plants D: Lions and Antelopes

I'm taking a test and have to guess the right answer to the question after the article. Article: Sorry to say, our brains naturally start slowing down at the cruelly young age of 30. it used to be thought that this couldn't be helped, but new studies show that people of any age can train their brains to work faster . "Your brain is a learning machine," says prefix = st1 /UniversityofCaliforniascientist Dr. Micha3el Merzenich. Given the right tools, we can train our brains to act like they did when we were younger. All that's required is the practice designed just for the purpose: a few exercises for the mind. Merzenich has developed a computer-based training method to speed up the process  in which the brain deals with information (positence. com). Since much of the data we receive comes through speech, the Brain Fitness Program works with language and hearing to better speed and accuracy .  Over the course of training, the program starts asking you to distinguish   sounds (between "dog" and "dog", for example) at an increasingly faster speed. It's a bit like tennis instructor, says Merzenich, hitting balls at you faster and faster to keep you challenged  . You may start out slow, but before long you're pretty quick. The biggest finding in brain research in the last ten years is that  _ If you ask your brain to learn, it will learn. And it may even speed up while in the process. To keep your brain young and plastic you can do one of a million new activities that challenge and excite you: playing table tennis or bridge, doing crossword puzzles, learning a language...."When it comes to preventing ageing, you really do 'use it or lose it", says Barbara Sahakian, professor at CambridgeUniversity. Question: Dr. Merzenich's training method mainly depends on    _  . Options: A: speech training B: computer languages C: the activities one joins in D: the information being dealt with

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: If your family is thinking of getting a pet, consider adopting from an animal shelter. Animal shelters are full of dogs, cats, rabbits, and more animals, all in need of loving homes. Some may come with emotional or behavioral issues, but most are happy, healthy, and ready for a loving home. Here are some tips for you to find great animals. Make some decision. Think about what you want in a pet and remember that all pets have different personalities. Cats tend to be more independent and need less affection, but kittens need lots of attention. Cats don't need to be walked, but you need to clip their nails and play with them. Dogs need to be walked at the very least twice a day. However, they are usually great companions and love to spend time with their family. Visit the shelter. Set aside at least a few hours to visit shelters in your area--remember that you may need to visit more than one visit. Try to bring along everyone who will be living with a new pet. Ask the shelter staff lots of questions. And never adopt an animal because you feel sorry for it--be patient so you find a pet who is truly a good match for your family. Get everything ready. Buy all necessary supplies and food well before the animal comes home. Make sure that the entire household is in agreement about rules and responsibilities--will the dog be allowed on the couch? Who will clean the litter box? Put it in writing before the pet arrives. Bring your new friend home! You'll probably be excited when your new pet arrives, but be sure to give them space and time to get adjusted to a new home and a new family. The pet may act differently once they leave the shelter. Interact with your pet a lot and get them used to a routine, and soon you'll be one big happy family ! Question: The article is most likely intended for   _  . Options: A: animal shelters B: shelter staff C: pet lovers D: pet protectors
A: C

I'm taking a test and have to guess the right answer to the question after the article. Article: At the age of sixteen,I joined a volunteer group with my dad. I went on my first volunteer project in West Virginia. On the night we arrived, we discovered that "our family" was living in a trailer  that was in poor condition. A crew had been working on it for two weeks,but every time they finished one problem,another surfaced(, ).  We decided the only reasonable solution was to build a new house--something unusual but necessary under these circumstances. The family was overjoyed with their new house that was twenty by thirty feet with three bedrooms,a bath and a kitchen.  On Tuesday of that week, while we were eating lunch together,I asked the family's three boys,Josh,Eric and Ryan,"What do you want for your new room?"Expecting toys and other gadgets that children usually ask for, we were astonished when Josh responded,"I just want a bed." The boys had never slept in a bed! They were accustomed to plastic mats. That night we had a meeting and decided that beds would be the perfect gift. On Thursday night, a few adults in our group drove to the nearest city and bought beds and new bedding.  When we saw the delivery truck coming,we told the family about the surprise. We could hardly control ourselves. It was like watching excited children on Christmas morning.  That afternoon, as we fitted the frames of the beds together, Eric ran into the house to watch us. Too dirty to enter his room,he observed with wideeyed enthusiasm from the doorway.  As my father slipped a pillowcase  onto one of the pillows,Eric asked,"What is that?" "A pillow," he replied.  "What do you do with it?" Eric continued to ask.  "When you go to sleep,you put your head on it," I answered softly. Tears came to my eyes as my father handed Eric the pillow.  "Oh...that's soft," he said,hugging it tightly.  Now,when my sister or I start to ask for something that seems urgent,my dad gently asks,  "Doyouhaveapillow?" We know exactly what he means. Question: On hearing Josh's answer,  the writer was shocked because  _  . Options: A: the family lived in a trailer B: he expected to get some toys C: he didn't know what a bed was D: the boys had no bed to sleep in
