Q: I'm taking a test and have to guess the right answer to the question after the article. Article: "Plants were expected to get larger with increased carbon dioxide in the atmosphere, but changes in temperature, humidity and nutrient availability seem to have _ the benefits of increased carbon dioxide," said researchers from the National University of Singapore. 45 percent of the species studied now reach smaller adult sizes than they did in the past. The researchers point out that warmer temperatures and changing habitats, caused by climate change, are possible reasons for the shrinking of creatures. "We do not yet know the exact mechanisms involved, or why some organisms are getting smaller while others are unaffected," the researchers said. "Until we understand more, we could be risking negative consequences that we can't yet quantify." The change was big in cold-blooded animals. Only two decades of warmer temperatures were enough to make reptiles smaller. An increase of only 1degC caused nearly a 10 percent increase in metabolism . Greater use of energy resulted in tiny tortoises and little lizards. Fish are smaller now too. Though overfishing has played a part in reducing numbers, experiments show that warmer temperatures also stop fish growth. There is a recent report on warmer temperatures' negative effects on plankton ,the base of the marine ecosystem. Warm-blooded animals weren't immune from the size change caused by climate change. Many birds are now smaller; Mammals have been miniaturized too. Soay sheep are thinner. Red deer are weaker. And polar bears are smaller, compared with historical records. This isn't the first time this has happened in Earth's history. 55 million years ago, a warming event similar to the current climate change caused bees, spiders and ants to shrink by 50 to 75 percent over several thousand years. That event happened over a longer time than the current climate change. The speed of modern climate change could mean organisms may not respond or adapt quickly enough, especially those with long generation times. So, it is likely that more negative influences of climate... Question: Researchers from the National University of Singapore believe that _ . Options: A: how climate change affects animals' sizes has not been found clearly B: all the animals on the Earth have become smaller C: too many studies on animals' sizes have been done D: climate change has more negative effects on warm-blooded animals
A: A

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: B Gift Idea The other day I was shopping for Grandma when I realized I had no gift ideas at all. It was not a birthday gift or anything like that. It was simply sort of a hello gift. That is how we do things in my family. We don't really give gifts for special occasions. Instead, we occasionally just give presents to each other to tell other people that we are thinking about them. That was why I wanted a gift for Grandma. But it was like my imagination had dried up. I have gone through all of the gift ideas in previous years, fruits, wines, cheeses, little handmade crafts, and anything else that you can give to a grandmother. I had even given her gift watches, and CDs. What else was there? I have always found gift ideas for men a little bit easier than for women, because for men, you can always get the usual things, such as video games, power tools and things like that. With a woman's gift idea, however, you have to know more about her. You cannot just get someone a book or a CD. You have to know all about her taste in movies, music, and literature. My grandmother likes to read a lot, but what she likes is always pretty popular. I didn't want to get her a book that she might not like, but I was running out of time. I needed a gift idea for this weekend and went to visit her. After all, I hadn't seen her for a long time. I wanted to give her a gift so she would not feel ignored. Finally, I came up with the perfect gift idea. I made a collection of all the stories I had written in the past year. It wasn't a typical gift idea like a bunch of flowers, but it really worked in the situation. You see, I am a writer and my grandma has always been my fan. Anyway, I had been learning about bookbinding recently, and had pretty much mastered the art. I figured that I would add a little bit of handmade artwork to the stories, bind it altogether, and give it to her. It took hours to complete, but it was well worth the effort. She ly loved it. Question: How does the writer feel about giving gifts to women? Options: A: Interesting. B: Challenging. C: Time-wasting. D: Popular.
