The agreement came after two weeks of talks between the leaders at the 21st Conference in Paris, France. As part of the Paris agreement, countries said they would cut down on pollution However, according to the terms of the deal, countries that don't do this will not be punished, or fined. Instead,the document is meant to show that governments around the world take climate change seriously and are willing to work together to fight global warming. World leaders have met many times to discuss climate change. But, the 21st Conference of Parties, or COP21, which began on November 30 in Paris, was the first time they agreed on a global, legal pact . Before the conference, each nation was asked to create plans on how to reach the shared goal. The pact that was signed allows countries to decide the best way to cut down their gas pollution. No matter how they decide to go green, each country must report honestly on all of their efforts. Every five years, nations must look at the work they've done and submit new plans on how they will improve over the next five years. In the pact, the countries pledge to limit the amount of greenhouse gases emitted by human activity to the levels that trees,soil and oceans can absorb naturally. It urges countries to spend trillions of dollars on creating new energy sources, like solar and wind power. It also requires countries to raise at least $ 100 billion each year to help developing countries. However, critics of the pact say it is not detailed enough, and doesn't include specifics about how the plan will be enforced and how improvements will be measured. The pact does include one large, specific goal: how countries will aim to keep global temperatures from rising more than 3. 60degF(20degC) by 2100. Nonetheless,the agreement is considered by many world leaders to be a major victory. The U. N. has been working more than two decades to convince governments to work... Question: According to the agreement, countries _ . Options: A: have to give a yearly report about their work B: will be published if they fail to reduce pollution C: are required to ensure investment in fighting pollution D: should try to reach the agreed standard in five years

Read the article and select the best answer. Article: Do you suppose Darwin, one of the greatest scientists of all time, really did fools' experiments? Or did he do experiments that were so simple and basic that other people just thought they were foolish? Sometimes, people think they already know the answer to a question or the solution to a problem. Sometimes, they really do know an answer or a solution, but without thinking they are important. Charles Darwin didn't settle for just thinking he knew something. And, he believed all things could be important however simple they seemed to be. Suppose you drop sheets of paper that are of exactly the same size and shape. If you drop them at the same time in the same place, they will fall in the same way. Now make one of the sheets of paper into a tight little ball and let it drop along with the other sheets. What happens? You have done an experiment that is so simple that you might think it couldn't be worth anything. But this simple experiment is important. It explains part of our present day understandings of physics ideas that were worked out long ago by Galileo and Newton. And these understandings set aside some of ancient Greek physics. Scientist sometimes stops to look at very simple things and to think very hard about them. Even the simplest idea, which we might think is foolish, can shake the foundations of science. Question: The passage tells us that Charles Darwin_. Options: A: was a great English scientist B: always liked doing the experiments that others thought difficult C: thought even the simplest thing was important D: didn't get well with others

Ques: Read the article and select the best answer. Article: George Gershwin, born in 1998, was one of America's greatest composers. He published his first song when he was eighteen years old. During the next twenty years he wrote more than five hundred songs. Many of Gershwin's songs were first written for musical plays performed in theatres in New York City. These plays were a popular form of entertainment in the 1920s and 1930s. Many of his songs have remained popular as ever. Over the years they have been sung and played in every possible way -- from jazz to country. In the 1920s there was a debate in the United States about jazz music. Could jazz, some people asked, be considered serious music? In 1924 jazz musician and orchestra leader Paul Whiteman decided to organize a special concert to show that jazz was serious music. Gershwin agreed to compose something for the concert before he realized he had just a few weeks to do it. And in that short time, he composed a piece for piano and orchestra which he called Rhapsody in Blue. Gershwin himself played the piano at the concert. The audience were thrilled when they heard his music. It made him world-famous and showed that jazz music could be both serious and popular. In 1928, Gershwin went to Paris. He applied to study composition with the well-known musician Nadia Boulanger, but she rejected him. She was afraid that classical study would ruin his jazz-influenced style. While there, Gershwin wrote An American in Paris. When it was first performed, critics were divided over the music. Some called it happy and full of life, to others it was silly and boring. But it quickly became popular in Europe and the United States. It still remains one of his most famous works. George Gershwin died in 1937, just days after doctors learned he had brain cancer. He was only thirty-nine years old. Newspapers all over the world reported his death on their front pages. People mourned the loss of the man and all the music he might have still written. Question: What do we know about the concert organized by Whiteman? Options: A: It attracted more people to theatres B: It proved jazz could be serious music C: It made Gershwin leader of the orchestra D: It caused a debate among jazz musicians
