Q: Read the following article and answer the question. Article: At age 61, identical twins Jeanne and Susan no longer look exactly alike. Susan smoked for many years and is an admitted sun worshipper, whose habits Jeanne does not share. A new study of twins suggests you can blame those coarse wrinkles, brown or pink spots on too much time in the sun, smoking, and being overweight. Because twins share genes, but may have different exposures to environmental factors, studying twins allows an "opportunity to control for genetic susceptibility ," Dr. Elma D. Baron, at Case Western Reserve School of Medicine in Cleveland, Ohio, and his colleagues explain in the latest issue of Archives of Dermatology. Their analysis of environmental skin-damaging factors in 65 pairs of twins hints that skin aging is related more to environment and lifestyle than genetic factors. But when it comes to skin cancer, the researchers say their findings support previous reports that both environment and genes affect skin cancer risk. Baron's team examined facial skin of 130 twins, 18 to 77 years old, who lived mostly in the northem Midwest and Eastern regions of the US, who were attending the Twins Days Festival in Ohio in August 2002. At this time, each of the twins also separately reported how their skin burned or tanned without sunscreen, their weight, and their history of skin cancer, smoking, and alcohol drinking. The study group consisted of 52 fraternal and 10 identical twin pairs, plus 3 pairs who were unsure of their twin status. From these data, the researchers noted strong ties, outside of twin status, between smoking, older age, and being overweight, and having facial skin with evidence of environmental damage. By contrast, sunscreen use and drinking alcohol appeared related to less skin damage. Baron and his colleagues say the current findings, which highlight ties between facial aging and potentially avoidable environmental factors--such as smoking, being overweight, and unprotected overexposure to the sun's damaging rays--may help motivate people to minimize these risky behaviors. Question: Why did Baron's team do the research on twins? Answer:

OPTIONS:
- Twins are more likely to suffer from skin cancer.
- It may guarantee the research is not influenced by genetic factors.
- It gives others an opportunity to control twins' genes.
- It helps find twins are exposed to different environments.

A: It may guarantee the research is not influenced by genetic factors.

Q: Read the following article and answer the question. Article: The Mona Lisa Leonardo da Vinci began painting the Mona Lisa in 1503. He was working on a special painting for a church at the time, but the church painting was not going well. An Italian businessman asked da Vinci to paint a picture of his second wife. This is the woman who can be seen in the Mona Lisa. All in all, the Mona Lisa is a very good example of da Vinci's works. Da Vinci used darkness and light in a clever way in the painting. Da Vinci loved science and math. Right away a person can see that there is a lot of geometry in the Mona Lisa. The face of the Mona Lisa is made of many circles and round shapes like balls. Even her smile can be seen as a small part of a large circle. The woman in the painting is sitting on a balcony ,and mountains can be seen behind her. Da Vinci loved to study rocks and mountains, so these can be seen over and over in his other paintings. The woman is sitting with her knees to the side. Her head is turned to look out of the painting. Her hands are held together in front of her. This way of sitting is now used by many artists when they are painting a picture of a man or a woman today. Question: The woman in the painting is _ Answer:

OPTIONS:
- an Italian businesswoman
- the wife of a businessman
- Leonardo da Vinci's wife
- a woman from the church

A: the wife of a businessman

Q: Read the following article and answer the question. Article: An anxious mother watched as rescuers freed her baby from a muddy well. After being pulled from the well,the baby joyfully ran to its mom as the rescuers took a break. It was a difficult and potentially dangerous rescue: the baby was an 8-month-old elephant, and at first its mother thought the humans were trying to harm it. The baby elephant fell into the five-foot-deep well near Kenya's Amboseli National Park. Local people had dug the well for water. It took 30 minutes to remove the trapped elephant. While Vicki Fishlock of the Amboseli Trust for Elephants made a loud shout to frighten the mother away, two men struggled to get a rope around the baby elephant. Once the rope was in place, Fishlock used her jeep to pull the baby out. Fishlock recognized Zombe, the mother of the trapped baby elephant,from a mark on her ear. She believes that in the end Zombe realized the humans were trying to help. "Rescues where the elephant's family members are around are always stressful, and I'm always happy when everyone is safe," Fishlock said."The reunions always bring tears to my eyes. The depth of their love for each other is one of the things that make elephants so unusual." The very next day, another baby elephant fell into the same well. The 3-month-old's family had been driven away from the area by local people. Once it had been rescued, the Amboseli Trust had to send it to an elephant orphanage in Nairobi, Kenya's capital city. The rescues showed the _ of elephants across Africa. Elephants are fighting to survive, as conflicts between the animals and humans are increasing. Thousands of elephants are also being killed for their tusks. The tusks are sold in Asia, where ivory trinkets are in high demand. The Amboseli Trust has been studying elephants and trying to help them since 1972. Fishlock said, "We hope this rescue persuades people that elephants are special and deserve to be protected and treasured." Question: What causes Fishlock to think that elephants are special? Answer:

OPTIONS:
- Their trust in humans.
- The deep love between them.
- Their great ability to survive.
- The good communication between them.

A: The deep love between them.

Q: Read the following article and answer the question. Article: When I was six, my mother placed me in a boarding home. For the next nine years, I never slept in a room that contained less than 30 other kids in it. So, when I was promoted to senior at the high school for my final year there, I had the greatest pleasure of rooming with just one other classmate, and the added feature of a semi-private bathroom. We seniors also had the feature of walking around the campus in special hats, we called senior bonnets. So all the other kids would know we were the highest in the high school. As seniors, we frequently went on field trips outside the campus, including city museums, city hall, colleges and theatres. The highlight was a senior class trip to Washington, D.C., where we sat in on a session of Congress, visited the monument and many other government sites around the city. Another benefit of being seniors was that many of us on athletic and other extra-curricular teams were elected to high ranking for the year. I had the honor and pleasure of being chosen captain of our state championship swim team, while my roommate was voted president of the drama club. Graduation services were on a sunny day in June. Each of us had looked forward to this moment for ten years. Now we were going out on our own to complete freedom, and we should have been flooded with joy. However, to my surprise, I found myself crying, something I hadn't done for years. I noticed many of my classmates usually proud of their macho guy attitudes, were also wiping away tears. We knew we would never be together again as we were on that graduation day. Our senior year ended with deep feelings of sadness for our loss, as well as joy for our emerging into a new world beyond the school campus. Question: Why did the author and his classmates wear senior bonnets at campus? Answer:

OPTIONS:
- He could prove that they were from rich families.
- They would be respected by the girls in his class.
- Students of the lower grades would know their grades.
- They would look fashionable and attractive.

A:
Students of the lower grades would know their grades.
