I'm taking a test and have to guess the right answer to the question after the article. Article: Every student can learn rope jumping. You can jump alone or with your classmate. You can also help turn a long rope for many others to jump over, one at a time. If you jump alone, you will need a short rope and it will be just enough for your height. Try ropes of different lengths until you find a right one for your size. A rope should be turned slowly. It must also be turned high enough to let you jump freely and safely. Turning the rope freely and safely needs careful timing. In rope jumping, timing means turning the rope slowly enough for you to jump over at the right time without its striking your feet. When you jump rope, your heart beats faster and your face has a healthy color1. But if you jump too many times at first, you will get fired. You must learn when to stop for a rest before you jump again, If you practice, you can increase the number of limes you jumpers without resting. Question: Which of the following is true? Options: A: A rope must be turned as slowly as possible. B: A rope must be turned as high as possible. C: People can do rope jumping without resting. D: Careful timing is needed to turn a rope.

I'm taking a test and have to guess the right answer to the question after the article. Article: Internet reports of whales sounding like people are not new. But in this case in San Diego, California, scientists for the first time recorded the utterances, did an acoustic analysis and were surprised to find a rhythm similar to that of human speech, Sam Ridgway of the National Marine Mammal Foundation reported on Monday. The sounds marking is quite special : Whales make sounds through the system of the nose, unlike people, who use their throat. So this particular with whale had to make some tricky muscular and blowhole adjustments. "Such obvious effort suggests motivation for relatin", said Ridway, the main author of a study featured in the journal Current Biology. "The sounds we heard were clearly an example of vocal learning by the white whale." The wale, named Noc, died five years ago. Ridgway says that back in 1984, he and others started hearing sounds near the whale and dolphin enclosure that recalled two people speaking in the distance, too far away to be understood. The sounds were later traced to one particular white whale when a diver in its tank came to the surface because he thought he heard colleagues tell him to do so. Noc had lived among dolphins and other white whales and had often been in the presence of humans. The whale made human-like sounds for around four years until it reached the age of sexual maturity, Ridgway said. Question: Noe's making human-like sounds disappeared in _ . Options: A: 1984 B: 2012 C: 2007 D: 1988
(Answer)
D

I'm taking a test and have to guess the right answer to the question after the article. Article: prefix = st1 /Indonesiais known as the country of islands. It has 17,508. But in recent years, the popular tourist destination has lost some of its shine. Due to rising sea levels caused by global warming, 24 Indonesian islands have gone under the sea. Scientists say 2,000 more will disappear before 2030. In the past three years, the southeast Asian nation also witnessed its islands destroyed by a tsunami and typhoons. "If no measures are taken to fight climate change, the beautiful islands will go forever." scientists told environmental ministers from about 190 countries at a UN climate change meeting. This week they are meeting in Bali, an Indonesian islands. They are trying to reach a deal to cut the world's emissions of CO2, which makes the earth warmer. Indonesia is not alone. This year has been more _ hit the world.Canadaand US suffered heavy storms and typhoons, While Australians were caught in the heaviest drought in a century. In China, the average temperature this year went up by 1.2degC from last year, reaching the highest on record since 1951. From Jiangxi and Hunan in the south to Heilongjiang andJilinin the northeast , one -third of farmland has suffered from a drought. However, other parts of the country got too much rain. More than 700 people were killed in floods, landslides and storms. "These weather extreme are the more obvious effects of global warming," said Song Lianchun, a climate expert. Scientists say time is running out. To escape from the worst effects, global CO2 emissions need to be cut from the levels they were at in 2000 by 50 to 85 percent by 2050. But in recent years climate change talks have been bogged down by arguments over who will pay the bill for cleaner technology. Developing countries are worried that the cut in emissions will slow their economic development. "Chinawill play a responsible and constructive role in the meeting," said Chinese Premier Wen Jiabao. The nation is now the world's second largest greenhouse gas emitter ."However, developed... Question: Climate change talks have become bogged down because countries cannot agree on _ . Options: A: who should be responsible for causing climate change B: who will pay for the cleaner technology needed to tackle climate change C: whether developed nations should help developing nations in solving climate change D: whether developing nations should cut emission of CO2
