Article: More than 4 in 10 cancers -- 600,000 in the UK alone -- could be prevented if people led healthier lives, say experts. The population of the UK is about 63,000,000. Latest figures from Cancer Research UK show smoking is the biggest avoidable risk factor , followed by unhealthy diets. The charity advises people to live healthily, limit alcohol intake and do regular exercise. According to the figures from 2007 to 2011, more than 300,000 cases of cancer recorded were linked to smoking. A further 145,000 were linked to unhealthy diets containing too much processed food. Obesity contributed to 88,000 cases and alcohol to 62,200. Sun damage to the skin and physical inactivity were also contributing factors. Professor Max Parkin, a Cancer Research UK statistician, says, "There's now little doubt that certain lifestyle choices can have a big influence on cancer risk, with research around the world all pointing to the same key risk factors." "Of course everyone wants to enjoy some extra treats during the Christmas holidays so we don't want to ban beef pies and wine but it's a good time to think about taking up some healthy habits." "Leading a healthy lifestyle can't guarantee someone won't get cancer but _ by taking positive steps." Public Health England says a healthy lifestyle can play an important role in reducing cancer risk. It says campaigns such as Smokefree, Dry January and Change4Life Sugar Swaps all aim to raise public awareness. It's important that we not only continue to make progress in noticing cancer earlier and improving treatments, but helping people understand how they can reduce their risk of developing cancer in the first place remains important in dealing with cancer.
Question: Which of the following is the third biggest avoidable cancer factor?
Options: (A) Obesity. (B) Alcohol intake. (C) Unhealthy diets. (D) Physical inactivity.
Asnwer: C
answer:
No

Article: Miami Beach is a top destination for vacationers from around the world --not to mention a location for sea turtles laying eggs. For years, female sea turtles have returned to the beaches where they were born to build nests for their next generation. As Miami Beach continues to develop; wildlife officials and volunteers are making sure the beach remains a welcoming place for these endangered animals. The sea turtle patrol starts his day at sunrise. "The reason we need to get out at first light is to make sure we see the tracks before anybody else gets out here, Bill Ahern says, "Something that weighs 350 pounds is going to leave evidence." Bill Ahern directs the sea turtle program in Miami-Dade county. His team monitors and marks nests left by sea turtles who lay eggs in the sand and then return to the sea. The patrols also work with beach residents to keep track of new nests and possible threats to existing ones. Nearly 65,000 turtles nested on Florida's Atlantic coast last year. A tiny part comes to Miami Beach where they face many risks. Tough laws have been passed to punishpoachers . And bright lights from nearby buildings can confuse newly born turtles, attracting them onto roads instead of into the ocean. "I recall in the mid-1960s, me and my beach buddies(policemen) would pick up hatchlings from the road and put them back in the water," he recalls .To avoid that problem, city officials have imposed limits on coastal lighting. Although most sea turtles hatch on their own, coming out at night, some have a harder time. In the future, the Sea Turtles Program hopes to do away with the hatchery. Educating beach-goers is a step in that direction. Each week, people are invited to see a release of newly born turtles recovered from nests. The experience helps sunbathers understand the role of the beach in the turtle's life cycle. "Only a part of the newly hatched turtles will escape predators and man-made dangers in their first year." Their instincts are so sharp ," Ahern says, "I'll face a turtle to the west, and then watch him, he turns right around ,facing the ocean. "
Question: What do Ahern and his sea turtle patrol do in the early morning?
Options: (A) find tracks left by sea turtles (B) pick up the trash on the beach (C) collect eggs laid by sea turtles (D) exercise to lose weight
Asnwer: A
answer:
Yes

question:
Article: Walk through the Amazon rainforest today and you will find it steamy, warm, damp and thick. But if you had been there around 15,000 years ago, during the last ice age, would it have been the same? For more than 30 years, scientists have been arguing about how rainforests might have reacted to the cold, dry climate of the ice ages, but till now, no one has reached a satisfying answer. Rainforests like the Amazon are important for mopping up CO2 from the atmosphere and helping to solve global warming. Currently the trees in the Amazon take in around 500 million tons of CO2 each year: equal to the total amount of CO2 given off in the UK each year. But how will the Amazon react to the future climate change? If it gets drier, will it survive and continue to draw down CO2? Scientists hope that they will be able to learn in advance how the rainforest will manage in the future by understanding how rainforests reacted to climate change in the past. Unfortunately, collecting information is incredibly difficult. To study the past climate, scientists need to look at fossilized pollen kept in lake mud, Going back to the last ice age means drilling down into lake sediments , which requires specialized equipment and heavy machinery. There are very few roads and paths, or places to land helicopters and aeroplanes. Rivers tend to be the easiest way to enter the forest, but this still leaves vast areas between the rivers completely unsampled . So far, only a handful of cores have been drilled that go back to the last ice age and none of them provide enough information to prove how the Amazon forest reacts to climate change.
Question: How do scientists study the past climate change?
Options: (A) By predicting the climate change in the future. (B) By drilling down deep into land sediments. (C) By analyzing fossilized pollen in lake mud. (D) By taking samples from rivers in the Amazon.

Yes
