Read the following article and select the best answer. 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... Question: The information about Rose Bengal is wrong EXCEPT that _ . - it is no longer used as a dye - it is used to cure skin cancer - it is a special kind of rose planted in Australia - it can be effective in treating skin cancer
it can be effective in treating skin cancer

Q: Read the following article and select the best answer. Article: I am a manager who is in charge of taking care of the elderly and many of my clients live out of state. This year, a very sweet old lady that I care for, Alice, had gone through a particularly rough time. She had been in hospital twice. In November I was finally able to get her back to her "home" into an "assisted living facility" . Alice has dementia and thought her daughter was coming to visit her on Christmas day and that they were going to have the whole family together like the old days. When she finally realized that the happy moment was not going to happen, she was so _ . Knowing that her daughter was coming after Christmas was not enough to cheer her up, I hated the idea of her being alone on the holiday! On Christmas Eve, I gave her a surprise by asking if she would like to go to a candlelight service at church that night. Instead of taking her to my church, I took her to her old neighborhood church where all her friends were. We got there early and I got each of us a seat where her friends could see her as they came in. The plan worked out very perfectly. All of her friends seemed to be there and rushed over to greet her and sit with her. The candlelight service was a beautiful, tearful affair and Alice got a lot of hugs and love from her old and new friends there. The truth of the story is that I am the one who got the best gift:the smile on Alice's face and the feeling that I made a difference. Question: From the text we know that Alice _ . - had been operated in the hospital twice - didn't remember her daughter at that time - preferred to live alone especially at Christmas - expected to spend Christmas with her daughter
A: expected to spend Christmas with her daughter

*Question*
Read the following article and select the best answer. Article: When I was young, my mother didn't have the money to send me to school, but she thought it was important for me to keep up with education. So she decided to teach me extra lessons herself. But because she had to go to work, the only time she could do it was at 4:30 in the morning. We need every one of you to develop your talents and your skills so that you can help us old folks solve our most difficult problems. If you quit on school--you're not just quitting on yourself, you're quitting on your country. No one's written your destiny for you, because you write your own destiny. You make your own future. That's why today I'm calling on each of you to set your own goals for your education and do everything you can to meet them. Your goal can be something as simple as doing all your homework, paying attention in class, or spending some time reading a book. But whatever you decide to do, I want you to commit to it. I want you to really work at it. I know that sometimes you get that sense from TV that you can be rich and successful without any hard work--that your ticket to success is through rapping or basketball or being a reality TV star. No one's born being good at all things. You become good at things through hard work. You're not a good athlete the first time you play a new sport. You don't hit every note the first time you sing a song. You've got to practice. Question: What does the writer want everyone to do by improving their talents and skills? - To quit on their country to earn more money. - To offer help to the old people who have difficulties. - To write their own new destiny by working as TV star. - To spend some time writing books about their own life.
