Q: Read the following article and answer the question. Article: New software is able to analyze exactly how many hairs there are in a patch of skin and could help in testing the effectiveness of baldness treatments and depilatory creams, say Australian researchers. Researchers from CSIRO Mathematical and Information Sciences in prefix = st1 /Sydneyreport their findings in the November issue of the journalSkin Research and Technology. The software, developed with a UKcompany, will make it easier for researchers developing hair removal creams to accurately assess how well they work, says Dr Pascal Vallotton. "Up to now they were counting the number of hairs that survived after treatment by hand. That's hard work and it's difficult because you may count a hair twice or you may miss it." he said. The software relies on images captured by a small flatbed scanner pressed onto the skin. Using a mathematical algorithm , the software then identifies and traces each individual hair based on an understanding of a hair's unique features, such as its straightness. The software is able to distinguish between hairs and other features on the skin such as wounds or moles . "Our skin irregularities make it difficult to say this is a hair or this is a mole," Dr Vallotton said. Comparison between earlier and later images can also determine if hair is growing quickly or slowly, he says. Unfortunately, to check the accuracy of the software, the researchers still had to adopt the old-fashioned method of counting hairs, helped by volunteers from neighboring labs who put their skins on the line for science. "We had 12 volunteers, mostly from neighboring labs, and we acquired images of hair before and after treatment," Dr Vallotton said. To ensure an accurate count, the individual hairs had to be marked off as they were counted, but after such a laborious process, the researchers were pleased to discover the software results were comparable to the manual count. Dr Vallotton says the software could also be useful in testing the effectiveness of balding treatments and counting or tracing... Question: What do we know about the new software? Answer:

OPTIONS:
- It has replaced human labor completely.
- It is mainly used to detect hair problems.
- It can be used for develop new medicine.
- It can be used to test medical treatments.

A: It can be used to test medical treatments.

Q: Read the following article and answer the question. Article: Towards evening, Jennifer was walking on the beach with a gentle breeze blowing through her hair. Looking up at the golden red sun ball, she was surprised by its color, deep red in the middle, softly fading into yellow. She could hear nothing but the waves and the seagulls flying up above in the sky. The atmosphere relaxed her. This was what she needed. "It's getting late," she thought, "I must go home. My parents will be wondering where I am." She wondered how her parents would react when she got home after the three days she was missing. She kept on walking, directing herself to bungalow 163, where she spent every summer holiday. The road was deserted. She walked slowly and silently. Just in a few hundred meters, she would have been safe in her house. It was really getting dark now. She wished she had her favorite coat on. It might keep her really warm. She imagined having it with her. This thought dissipated when she finally saw her front door. It seemed different. Nobody had taken care of the outside garden for a few days. She was shocked: her father was usually so strict about keeping everything clean and tidy, and now... She entered the house. First, she went into the kitchen and saw a note written by her father, "Dear Ellen, there's some coffee ready; I went looking." But where was Ellen? On the right side of the hallway was her parents' room. She went in and saw her. Her mother, lying on the bed, was sleeping. Her face looked so tired, as if she hadn't slept for days. She was really pale. Jennifer would have wanted to wake her up, but she looked too tired. So Jennifer just fell asleep beside her. When Jennifer woke up something was different. She wasn't in her mother's room and she wasn't wearing the old clothes she ran away in. She was in her cozy bed in her pajamas . It felt so good being back home. Suddenly she heard a voice. "Are you feeling better now, dear? You know you got us very, very scared." Question: Jennifer decided to go home because _ . Answer:

OPTIONS:
- it was getting cold
- she realized her parents were worried
- she began to miss her parents
- she knew nobody would take care of the garden

A: she realized her parents were worried

Q: Read the following article and answer the question. Article: Have you ever wished that you could make your little sister's teddy bear talk to her? Or have you ever wanted to bring a puppet to life? If so, you may be interested in learning the art of ventriloquism . A ventriloquist can make an ordinary object seem to be alive by giving it a personality, movement, and speech. Your object can be a puppet, or a doll. Give your new "friend" a name, and then decide on the personality that he will have. The next step is to give your friend movements that agree with the personality you have chosen. Now you can learn to make your "friend" talk. A ventriloquist will control his mouth and lips so that it will appear that his voice is coming from the object he is using. This will take practice, but you can do it. First, decide on a voice that is different from your own. It could be higher or lower than yours, or could even have a special accent. Then, find a clean teaspoon and hold the handle between your front teeth. Now, using the voice you created for your friend and holding the handle of the teaspoon tightly between your teeth, look into a mirror and talk. Practicing with the spoon in your mouth will help you learn to keep your mouth from moving. Now try telling a joke in your normal voice and have your friend speak in his voice. Practice those words until you can say them without your lips moving at all. Ventriloquism is fun. It also requires hard work to become good at it. The most important thing to do is practice. But if you are willing to take the time to give your friend an interesting personality, to practice lively movements, and to work on good mouth control, then you will be well on your way to becoming a ventriloquist!
