Article: "Plants were expected to get larger with increased carbon dioxide in atmosphere, but changes in temperature, humidity and nutrient availability seem to trumped 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 pointed out that warmer temperatures and changing habitats, caused by climate change, are possible reasons for shrinking creatures. "We do not yet know the mechanisms involved, or why some organism 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 coldblooded animals. Only two decades of warmer temperatures were enough to make reptiles smaller. An increase of 1 degree centigrade 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. Warmblooded 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 is not 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 long 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: too many studies on animals' size have been done B: all the animals on the earth have become smaller C: how climate change effects animals' size has not been found clearly D: people can avoid the negative effects of climate change
C

Read the article and select the best answer. Article: The Nobel Prizes in physiology or medicine, physics and chemistry are the most respected prizes in science. But talk to scientists in private, and many will complain why (besides jealousy, perhaps) are some scientists unhappy with the Nobels? One reason is that the committees can often be slow to recognize achievement. Alfred Nobel specified in his will that the prizes should reward work done in the previous year. But experience soon showed that this was risky, as medals were given out for discoveries that later proved questionable. So a degree of caution is probably advisable. Sometimes, though, it can lead to strange results. Subrahmanyan Chandrasekhar, for instance, had to wait until 1983 to win a prize for work he had done in the 1930s on the structure of stars. However, Albert Einstein never won a prize for his theory of relativity. Even though some pretty suggestive evidence had been produced by Arthur Eddington in 1919, relativity, which has later passed every experimental test ever thrown at it, was still considered somewhat risky and obscure. Another criticism concerns the tradition that no more than three people can share a prize. Science is rarely this clear-cut. Take this year's physics prize, which recognised Peter Higgs for predicting the existence of the mass-bestowing particle that now bears his name. Dr Higgs was only one of several people with a claim. Two other teams---- Rober Brout and Francois Englert, as well as Gerald Guralnik, Carl Hageh and Tom Kibble----- submitted papers on the same idea to the same journal that published Dr Higgs's work, all within a few months of each other. Science often works like this, with different people coming up with similar ideas at similar times. In the event, the committee decided to honour Dr Engler (Brout is dead, therefore unqualified), whose paper was earlier than Dr Higgs's but did not explicitly predict a particle, over Dr Guralnik and his collaborators, who were more comprehensive but published a few weeks later. Question: According to the passage why some of the scientists are unhappy with the Nobels? Options: A: because usually the Nobels award work done in the previous year. B: just because they envy those who have won the Nobles. C: because different people often come up with similar ideas at similar times. D: because the Nobles are quite possibly slow to recognize achievement

As Goodwill expands its social enterprise and life-changing mission services, America's heroes and their families are helping us strengthen communities. Goodwill is uniquely intended to connect retired soldiers and military family members with their next careers. Goodwill links retired soldiers and their families with a broad array of career and financial fitness services as they transition from the military into hometowns and careers across the country. Services include but are not limited to financial education, housing assistance, primary health care, meal service, transportation, and connection to rehabilitation services . In 2011, First Lady Michelle Obama and Dr Jill Biden carried out the Joining Forces plan to connect service men and women retired soldiers and their husbands or wives with the resources they need to find jobs. In April of that year, Goodwill set a new plan going, Goodwill for America's Heroes and Their Families, to expand its face-to-face career and family strengthening services. From April 2011 through March 2013, Goodwill has employed 1,856 retired soldiers and their families, and provided services to 99,386 retired soldiers and their families. And our commitment continues. With the support of the Bank of America Charitable Foundation, Goodwill launched Vested in Retired Soldiers in the communities of Atlanta, Houston, Los Angeles and San Antonio to help military retired soldiers and their families connect with the education, training and support services they need to succeed on the homefront. Goodwill also launched an initiative known as Operation: GoodJobs, as funded by the Walmart Foundation, which provides a complete career assessment and an individualized development plan that include a range of family needs, from basic needs like nutrition, shelter and child care, to specific job training identified in the assessment process for participants and their families. The initiative... Question: Which of the following services is offered by Goodwill to retired soldiers and military family members? Options: A: Job opportunities. B: Financial support. C: Work training. D: Child care.
