Article: Australian scientists say an organic compound used by Indian women to paint dots or bindi on their foreheads could hold the key to a breakthrough in cancer treatment. Rose Bengal was first used in the early 1900s as a dye for food, textiles and cosmetics. But now it is proving to be a useful weapon in the fight against skin cancer. Television advertisements constantly warn of the dangers of overexposure to the fierce sun. Among them is the possibility of the disease melanoma , a type of skin cancer. More than 1,200 Australians die every year from the disease. Initial trials of a solution of Rose Bengal injected into some melanoma cells have had a 75 percent success rate in controlling the disease. Professor John Thompson, the director of the Melanoma Unit at the University of Sydney, says this organic dye could become a powerful cancer-fighting treatment. "We believe it works by getting into the tumor cells and causing them to self-destruct. But the exact mechanism by which it works is not totally clear. It's not useful for people who have a primary melanoma. The treatment of primary melanoma is surgical excision ,"he said. "It's useful to inject tumors for people who have recurrences; when the primary treatment has failed and when recurrence in the area, or at more distant sites has occurred." About 90 percent of Australians who develop melanoma survive thanks to early diagnosis and treatment. If left untreated, however, the disease can be fatal. Convincing younger people in Australia about the dangers of overexposure to the sun is a battle campaigners are constantly waging. Veronica Manock, a 21-year-old student, had two major operations to remove a cancerous tumor from her leg. "I've had a lot of friends who just said 'I thought it was just, you know, I'll get a mole cut out and that's it', whereas I don't think people realize how much danger they're putting themselves into and how easy it is to stop something like this happening to you just from doing little things,"said Marock. Other researchers in Australia are investigating genetic treatments to skin cancer. There is a pressing need for such research to produce effective treatments. Australians, the majority of whom are fair-skinned , are four times more likely to develop a melanoma than people in Canada, the United States or Great Britain.

Options: (A) it is no longer used as a dye (B) it is used to cure skin cancer (C) it is a special kind of rose planted in Australia (D) it can be effective in treating skin cancer

Article: I believe children have a very pure sense of humor. Well, I would like to share my experiences with you. The other day when I was out with a friend and her daughter Jane at a restaurant, Jane ordered an apple dessert, which was the most attractive dish in that restaurant. However, when she had a bite of the pie, she shouted loudly, "Mom, why does it look good but tastes like rubber?" My friend was uneasy. Then the waiter gave us another dish. A child can say funny things. I was at a friend's home for tea and her son, Mark, wanted her to get up. His mom replied, "I can't, because my foot has fallen asleep now." Little Mark then sang a song and asked, "Mom, will it wake up now?" We laughed together. The other day we were having an interesting conversation over lunch and my friend, an animal activist , was arguing with another group member. Her son Tommy suddenly stood up, "Mom, people should never be allowed to shoot extinct animals!" That was funny and the child did manage to turn the argument into a pleasant conversation. Well, children sometimes really surprise us. I think we can have a lot to learn from them. They can help us understand the simple world through their eyes.
Question: Why did Jane shout loudly in the restaurant?
Options: (A) She wanted to make us laugh. (B) She thought her dish was attractive. (C) She wanted another piece of dessert. (D) She didn't like the flavor of her food.

Article: The passport photographs of the future could turn out to be more than just another pretty picture if a new computer technique developed by Israeli scientists catches on. Researchers at Ben-Gurion University, in Israel, have invented a way to hide information such as a fingerprint or signature in color images. They believe this could improve passport safety or be used to produce product bar codes or designs that cannot be seen. "The papers can be faxed, scanned and reprinted without hidden data disappearing," New Scientist magazine said last week. Joseph Rosen and a team of scientists worked out the new instrument by creating a mathematical model. The model turns a fingerprint or signature into a series of numbers which are used to shape the dots that make up a color picture. "Each dot can be forced out of the usual place slightly without noticeably changing the final appearance of the image," the magazine said. Several images that can be hidden in a single picture are scanned into a computer which does the work. The hidden images or fingerprints cannot be shown until the picture is scanned again. The computer rebuilds the fingerprint by measuring the displacement of the dots in the picture. The magazine said that if he model is used for passport checkpoints the picture can be unscrambled to show the fingerprint or signature and checked against the person holding the passport. The researchers are now working on a handheld, and instrument which could make unscrambling the hidden information easier.
Question: The new passport photos will probably contain all EXCEPT _ .
Options: (A) one's picture (B) one's fingerprint (C) one's signature (D) one's blood type
D
