Article: A terrible competition is going on in England, with billions of dollars and hundreds of lives at risk. OK, that's not true. But competitors from around the world gathered on Thursday for the annual competition to compete for the world's biggest person who tells lies. Each participant is given up to five minutes to make up the best _ in the contest, which was founded in honor of 19th-century Bridge Inn landlord Will Ritson, who was reportedly famous for his lies. Competitors gather at the Bridge Inn every year for the competition, a small pub in northwestern England. Anyone but lawyers and politicians can take part in the competition. A study found that nearly all lies are detectable through visible facial muscle reactions in the person telling a lie. "Thus, while interpersonal cheat often is highly successful, signs of hidden emotional states are communicated clearly to the informed observer," the study concluded. A churchman of Carlisle reportedly holds what may be the greatest lie of all time in the competition, simply stating, "I have never told a lie in my life." In 2003, Abrie Krueger from South Africa became the first one to win the competition. In 2006, comedian Sue Perkins became the first female to win the competition, telling a tale about people riding camels to work as a result of climate change.
Question: Why does the author tell a lie at the beginning of the passage?
Options: (A) He likes telling lies. (B) He intends to talk about a contest. (C) Lies can be detected by someone. (D) Nearly everyone has told lies.

Article: A rainfores is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely dipping below 16degC.Rainforests have a great effect on the world environment because they can take in heat from the sun and adjust the climate. Without the forest cover, these areas would reflect more heat into the atmosphere,warming the rest of the world .Losing the rainforests may also influence wind and rainfall patterns, potentially causing certain natural disasters all over the world. In the past hundred years, humans have begun destroying rainforests in search of three major resources : land for crops, wood for paper and other products, land for raising farm animals. This action affects the environment as a whole. For example,a lot of carbon dioxide in the air comes from burning the rainforests. People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit . There are two main reasons for _ . Firstly, when people cut down trees, generally they can only use the land for a year or two. Secondly, cutting large sections of rainforests may provide a good supply of wood right now, but in the long run it actually reduces the world' s wood supply. Rainforests are often called the world's drug store. More than 25% of the medicines we use today come from plants in rainforests. However, fewer than 1% of rainforest plants have been examined for their medical value. It is extremely likely that our best chance to cure diseases lies somewhere in the world's shrinking rainforests.
