I'm taking a test and have to guess the right answer to the question after the article. Article: Four decades ago a group of college students visited the mountains of Borneo to examine moth populations. Now a team of British scientists, including a member of the original trip, has returned to the same sites to repeat the survey. They have found that, due to rising temperatures, the insects now live 68 meters higher. Global warming is forcing tropical species uphill to escape the rising temperatures at a rate of nearly 2 meters a year, the new study from Borneo suggests. Since this was the only chance to repeat the original survey, the scientist did everything they could to do it exactly the same way, going at the same time of year, in July and August, using photographs to find the exact original sites of the moth traps. "While this is the first study of insects, a few other studies of tropical species are starting to appear," said Thomas. "If you look across all those studies, you'll find the same results, and it's extremely difficult to think of any other explanation for them." While some species might survive by finding places on the mountains with temperatures similar to those of their original habitats, others may run out of habitat on the rocky peaks, warns the study. In a paper in the journal Naturein 2004, Thomas and 13 other experts analyzed the habitats of 1,100 species on five continents, and estimated that on average one quarter were at risk of extinction. Last year a paper published in the Public Library of Science in the US warned that the risk of extinction in the tropics was becoming more and more serious. The authors, Jana and Steven Vamosi, estimated that 20-45% of tropical species were at risk of extinction. Question: We can learn from the passage that _ . Options: A: this survey of moths has been carried out many times B: some scientists have put forward other explanations for the results C: scientists tried to repeat the original survey D: 20-45% of tropical species were estimated to be at risk of extinction in 2004

I'm taking a test and have to guess the right answer to the question after the article. Article: I have a younger brother. To me , he is a fourteen-year-old kid named Joe, with blond hair and blue eyes. To others, he is different. Where I see a kid who just needs a lot more attention, others see a mentally disabled boy, a kid who cannot walk or talk or think for himself. I see someone who just makes daily routine a bit less routine. Others see an annoyance, a bother. This is not to say that I have never felt resentful toward Joe. He is my brother, and with that comes responsibility. "Gina, could you stay in tonight and watch your brother?" "Gina, do me a favor and feed him dinner and change his diaper later, please?""Could you come home right after school today and get Joe off the bus?" These are phrases that I have heard since I was twelve. And sure, they have made me resent my brother to a certain extent. I would think: that's not fair! Everyone else can stay after and be a member of this club, or get extra help from that teacher. Or, all my friends are going out tonight, why can't I? And, how come I have to feed him? He is not my son! However, the small amount of resentment I feel toward my brother is erased a thousand times over by what I have learned from him. Besides making me responsible from a young age, and helping me be more accepting of all kinds of people, he has taught me to be thankful for what I have. I know that there are moment in my life that I should cherish and that Joe will never experience. He will never laugh so hard that he cries. He will never feel the glory of a straight-A report card. He will never comfort a best friend crying on his shoulder. And he will never know how much his family love him. Because he will never know, it is up to me to know, every second , how lucky I am. It is up to me to realize that life should be lived to its fullest, and that you should always, always be grateful that God, or whoever are the powers that be, gave you the ability to live your life the way you were meant to live it. Question: The passage intends to tell us that we should _ . Options: A: value the glory of success B: appreciate what life gives us C: comfort unfortunate people D: treasure meaningful moments
