Question: Q: Read the following article and answer the question. Article: An evergreen tree is a Christmas tradition in many American homes. The tree is usually a pine or fir dressed with lights and other color1ful decorations. Families might buy a cut tree or go to a tree farm and cut one down themselves. Some people bring a live tree in a pot into their home for the holidays and then put it back outdoors. Some people rent a Christmas tree. Companies might bring the same live tree to the same family year after year. Or the tree might get planted in a park or someplace else where it could help the environment. There are some trees that can be reused year after year because they are made of plastic or metal. Or, instead of a tree, some people have a small, sweet-smelling rosemary   plant, cut to look like a little Christmas tree. Another plant that many people connect with Christmas is the poinsettia  . Poinsettias are native to Mexico. They can be white or pink, but most are bright red. They are named after the first American ambassador to Mexico. Joel Poinsett liked them enough to send some back to the United States. Babies or pets that chew on poinsettias might get sick. But experts say the plant is not as poisonous as some people think. Like millions of other houses, the home of America's first president is decorated for Christmas. George Washington's Mount Vernon Estate is in Virginia.

Q: Read the following article and answer the question. Article: Experts recently suggested that teens should start adopting early bedtimes. Before you dismiss it as a habit suited only for young kids, consider that there are serious advantages in being well-rested. And now, even more research suggests that putting phones away before going to sleep is important to teens' well-being. A new study from Seton Hall University School of Health and Medicine Science found that 62 percent of kids used their smart phones before bed, and it's causing less sleep and poor performance in school. Those teens who text  before bedtime tend to go to sleep later, and get up later in the morning. Such behavior can be associated with mental health issues like depression or anxiety. Besides, once teens do receive a text, experts found, they tend to respond right away. Then the text conversation continues -- resulting in an even later bedtime. The study's co-author Dr. Peter Polos says this leads to excessive stimulation  at night. Light from electronic devices can block the secretion  of melatonin -- a hormone  that promotes sleep, which makes sleep difficult in the face of overuse of smart phones at night. It's true! More screen time means less sleep time; other studies have suggested the same idea. As for a final piece of advice, Dr. Sushanth Bhat says, since getting the proper amount of sleep is very important for brain development and learning in the teenage years, our study should encourage parents and guardians   to limit adolescent smart phone usage at night. Keep in mind that teens aren't the only ones addicted to their phones! Adults can also benefit from setting a tech curfew  for themselves. After all, kids learn by example! Question: Melatonin can   _  . Answer:

OPTIONS:
- make sleep difficult
- lead to later bedtimes
- help people fall asleep
- wake people from a sleep

A: help people fall asleep


Q: Read the following article and answer the question. Article: Height is just one of the thousands of features your genes decide. In fact, because you have two parents, your genes provide you a height that usually lands somewhere between the height of each parent. If both your parents are tall, then most probably you will be tall, too, but if you have questions about how tall you're going to be, ask your doctor if he or she can help you find it out. But genes don't decide everything. For example, eating an unhealthy diet can keep you from growing to your ideal height. Getting plenty of sleep and enough exercise will help you grow to the expected height. No doubt you're wondering how fast you should grow. It depends. There's no perfect or right answer. Generally speaking, kids grow about 2 inches (6 centimeters) a year between age 3 and the time when they start puberty (when your body starts changing and becoming more grown up). Your doctor will know how your growth has been going over the years. Two centimeters here and 2 inches there are not nearly as important as the height you're at now, how you've been growing up to this point, and what other changes your body may be going through. Don't be scared if you seem to have grown a lot in a very short time. Everyone has a growth spurt  during puberty. The age for starting puberty is about 10 for girls and about 11 for boys. But it can be earlier or later ---between 7 and 13 for girls and 9 and 15 for boys. You'll usually begin to notice that you're growing faster about a year or so after your body starts to show the first changes of puberty. Question: If you want to know how fast and how tall you should grow,   _  . Answer:

OPTIONS:
- you should have enough exercise
- you can ask doctors for help
- you should save the environment
- You can record your growth during puberty

A: you can ask doctors for help


Q: Read the following article and answer the question. Article: People who speak or perform before the public sometimes may suffer from "Stage Fright. " Stage fright makes a person nervous. In the worst case  it can make one's mind go back and forget what one ought to say,  or to act. Actors, musicians, dancers, lawyers, even radio show hosts  have suffered from stage fright at one time or another. Diana Nichols is an expert in helping people free from stage fright at a medical centre in New York City. She helps actors learn to control themselves.

One way is to smile before going onto the stage. Taking two deep breaths also helps. Deep breathing helps you get control of your body. Miss Nichols persuades her patients to tell themselves that their speech or performance does not have to the perfect. It's all right to make a mistake. She tells them they should not be too cautious while they are performing. It is important that they should continue to perform while she is helping them. After each performance, they discuss what happened and find out what advice helped and what did not. As they perform more and more, they will fear less and less as much as 50%.
