Article: Although Paris is often considered the city of romance, close to a million adults who call it home are single. Many single people say that France's capital is one of the most difficult places to meet people. The complaints of this lonely group have inspired a new phenomenon known as "supermarket dating." At Galerie Lafayette Gourmet,singles can shop for more than just the items on their grocery list. They can look for someone who has blue eyes, brown hair,and is 1.8 meters tall,or whatever may be on their romantic shopping list. At this Paris location,single people of all ages can schedule their shopping for Thursday nights between 6:30 and 9:00 p.m. When they walk through the door,they pick up a purple basket to advise that they are looking for love. They try to arrive early because the baskets disappear quickly, and then they have to wait in line for their turn to wander the store aisles . With purple baskets in hand, shoppers can consider their romantic options while they pick out their groceries. When they are ready to pay, they can go to the checkout line for singles who want to chat. Most of the people who look for love in the supermarket are skeptical of Internet dating. They know that it is easy to embellish one's appearance or to lie about one's age over the Internet. The supermarket, on the other hand,is considered a safe and casual environment in which to meet a potential match. In addition, what one finds in another's grocery basket can say a thing or two about that person's character or intentions. Buying pet food can be a man's way of showing a potential match that he has a sensitive side. Women who fill their baskets with low-fat food show their healthy style of living. These ways it's possible to find much more than food at a grocery store.

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: Jules Verne was a Frenchman who was born in 1828 and died in 1905. He read a great many scientific books and wrote a number of exciting books about the things which he thought that scientists and inventors would one day be able to do.

In those days submarines had not been invented but he described an underwater ship very like a modern one. Many of the things Jules wrote about in his books more than a hundred years ago to look into the future, however, were surprisingly exact. In his book From the Earth to the Moon he wrote at the age of about forty, three men and a dog made a journey around the moon in a hollow ship fired from a gun. After going around the moon, they returned to the earth and splashed down into the sea not far from where the first real moon traveler landed in July, 1969.
