Question: Read the following article and answer the question. Article: What if our babies could somehow tell us what they're thinking about, what they want, and what makes them unhappy? Robyn Holt, researcher for Baby Talk New Zealand, says they can. Holt heard about baby sign language through an advertisement and decided to go along to a workshop . "Sign language is something that's always interested me, and I thought, it could be really cool to try this with a baby because we are always guessing all the time what they actually want." Holt started using baby sign language with her baby son Benjamin, now 12, and within two weeks he started to sign the sign for milk. She has since used it with her two younger sons Dominic, 8, and Matthew, 3. Baby sign language is nothing new: the practice (which is based on adult sign language) has been out in America for more than 30 years. But it is enjoying a rebirth in New Zealand. The idea behind baby sign language is that babies do have the ability to communicate their needs if they are given the right tools to do so. Although many mothers develop an intuition about whether their baby's crying is from hunger, tiredness, or pain, baby sign language creates a direct form of communication that unlocks _ . When babies are between 6-months and 12 to 13-months, parents can begin to teach them sign language: use the sign for milk while feeding, and also talk about milk, so that the child begins to make the link in their brain. Then they can begin to add other signs, i.e. food, sick or pain. "I know of one parent. Her child was signing the sign for hurt by his mouth, and she realised his first teeth were growing. It makes life so much easier," said Holt. Question: Why did Holt go to the baby sign language workshop? Answer:
OPTIONS:
- To entertain her own children.
- To better understand babies' needs.
- To help babies with language problems.
- To develop a new system of sign language.
Answer: To better understand babies' needs.

Question: Read the following article and answer the question. Article: Dr. Jack M. Gwaltney, Jr. a professor at the University Of Virginia School Of Medicine infected six student volunteers with virus, the most common cause of colds. A few days later, when they were coughing and sneezing, he gathered 37 more people and divided them into three groups. Group 1 members spent three days and nights in the same room with one of the infected students, separated by a screen so they couldn't touch one another. Group 2 sat around a table while an infected volunteer talked, coughed and sang to them. Group 3 held hands with an infected student for ten seconds, and then touched their own noses or eyes. Although most scientists at the time, the mid-70s, believed colds were spread by virus-laden droplets spread through the air when infected people coughed or sneezed, Gwaltney suspected physical contact might play an important role. Sure enough, of the 15 people who had touched a student volunteer, 11 became infected--compared with only one of those who had been sitting at the table, and none who had spent three days and nights together. "The best evidence we have is that hand-to-hand contact is the most efficient way of transmitting virus," says Gwaltney. The study was one of a series that helped establish Gwaltney's reputation as a leading authority. Dr. Robert Couch says, "It would not be inappropriate to call him Mr. Common Cold." When Gwaltney is asked how close scientists are to finding a cure, he replies: "If you mean 'get rid of', I don't think we're going to be able to do that with cold viruses any time soon. But if you look in the dictionary, you'll see that 'cure' is explained as a successful treatment. And we're not just getting more effective at treating the symptoms --we're getting at the root cause too. " Question: Which of the following statements is TRUE according to the passage? Answer:
OPTIONS:
- Dr. Gwaltney was sure that hand-to-hand touch is the cause of the common cold.
- Only one of the people who had spent three days and nights together became infected.
- Dr. Gwaltney conducted many an experiment as to the cause of colds.
- Dr. Gwaltney tested altogether 43 volunteers to see how they could develop colds.
Answer: Dr. Gwaltney conducted many an experiment as to the cause of colds.

Question: Read the following article and answer the question. Article: Archaeology, like many academic words, comes from Greek and means, more or less, "the study of old things". So, it is really a part of the study of history. However, most historians use paper evidence, such as letters, paintings and photographs, but archaeologists learn from the objects left behind by the humans of long ago. Normally, _ are the hard materials that don't break down or disappear very quickly--things like human bones and objects made from stone and metal. It is very unusual to find anything more than the hard evidence of history--normally, the bacteria in the air eat away at soft materials, like bodies, clothes and things made of wood. Occasionally, things are different. In 1984, two men made an amazing discovery while working in a bog called Lindow Moss, in the north of England. A bog is a very wet area of earth, with a lot of plants growing in it. It can be like a very big and very thick vegetable soup--walk in the wrong place and you can sink and disappear forever. The men were working when one of them saw something sticking out--a human foot! Naturally, the men called the police, who then found the rest of the body. Was it a case of murder? Possibly--but it was a death nearly two thousand years old. The two men had found a body from the time of the Roman invasion of Britain. Despite being so old, this body had skin, muscles, hair and internal organs--the scientists who examined him were able to look inside the man's stomach and find the food that he had eaten for his last meal! Why was this man so well preserved? It was because he was in a very watery environment, safe from the bacteria that need oxygen to live. Also, the water in the bog was very acidic. The acid preserved the man's skin in the way that animal skin is preserved for leather coats and shoes. How did he die? Understandably, archaeologists and other scientists wanted to know more about the person that they called "Lindow Man". His hands and fingernails suggested that he hadn't done heavy manual work in his life--he could have... Question: Which is the best title for the passage? Answer:
OPTIONS:
- An Amazing Archaeological Discovery
- Archaeology and History
- What Is Archaeology?
- The Death of "Lindow Man"
Answer:
