Question: Article: The nervous-looking young man had waited for a few moments--outside the jeweler's before he got enough courage to enter. He was warmly greeted by a young assistant. James felt a rush of blood to his face as he explained he would be bringing in his future wife to choose a birthday present. The assistant listened carefully and told him he'd better buy a necklace. He wasn't used to buying jewellery and was a little worried about over-spending. After some discussion as to a reasonable price and the type, the assistant showed him dozens of necklaces and helped him to choose. At last James chose one and left the shop promising to return at five o'clock. When, half an hour later than planned, James did return to the shop with his future wife, Laura, the assistant acted as if she had never seen him before. When she was asked to show them some necklaces, she first brought out some inexpensive ones for them to choose, and then gave them the one she had prepared. A choice was soon made and they went away satisfied. James would certainly come back to buy what he wanted.

Question: Article: Do your parents smoke? Where do they smoke - outside, at work or at home when you are around? According to a survey published in the journal Academic Pediatrics, an alarming number of US parents are still risking their children's lives by smoking in front of them. Half of all children aged 6 to 19, even those with asthma , have been exposed to second-hand smoke in the country, reported Reuters. "It's well known that smoking kills, but many smokers still don't realize the damage their smoke causes to those around them," Dame Sally, Chief Medical Officer for England, was quoted by the Independent as saying. Tobacco smoke contains more than 7,000 chemicals, hundreds of which are poisonous. About 70 of them can cause cancer, not to mention other diseases, according to the US Centers for Disease Control and Prevention. What's most scary is that there is no safe level of contact with second-hand smoke---even "low-level" exposure can be harmful to one's health. And "low-level" means when a parent or family member smokes in another room or even outside. While second-hand smoke can be harmful to people of all ages, children face a greater risk than adults: they have smaller lungs; they breathe more quickly; and they have less developed immune systems. Also, young children have little control over their surroundings. Babies can't move to another room because the air is smoky. They depend on the adults in their lives to make sure that their environments are safe. Recent years have seen second-hand smoke exposure drop---but for adults rather than kids, because policies have been started around the world to ban smoking in public places such as offices, bars and restaurants. However, "Children tend to be exposed to second-hand smoke in homes and cars, and these places are not included in most laws and policies," Amy Ferketich, a researcher at The Ohio State University, US, told Reuters. So what can we do to limit children's exposure to second-hand smoke? Parents should stop smoking for good. But if they can't, they should never smoke---or let others smoke---around their children.
Question: Which of the following is TRUE according to the article?
Options: (A) Half of the children ages 9 to 18 in the US have parents who smoked at home. (B) Most smokers in the US don't care about the effects that smoking can have on those around them. (C) Dame Sally believes many parents who smoke in front of their kids have no idea of the damage that they are doing. (D) Hundreds of chemicals contained in tobacco can cause cancer.

Answer: C

Question: Article: In the late 1500s, a large powerful gun was placed on top of the Signal Hill, in prefix = st1 /Newfoundland, to prevent attacks from the outside. Flags were also flown there to warn sailors of bad weather. It's fitting, then, the Italian Gulielmo Marconi should have chosen this site to receive the world's first radio signal -- in Morse code -- from England on December 12, 1901. Marconi, combining earlier ideas with his own, led us to a new communications age. For the next 50 years, until the appearance of television, radio ruled the air waves. Today, it's the TV that rules. No single person can say to have invented television. In 1884, the German Paul Nipkow invented a device that sent pictures mechanically , and in 1906, Boris Rosing, a Russian, used a ray and a disc to create the world's first TV system. Then in the early 1920s, another Russian, Vladimir Zworykin,invented a picture display tube. He took out a patent for color1 TV, even though it wouldn't be developed for another 25 years. In 1924, a Scot entered the scene -- John Logie Baird. He first succeeded in sending a moving picture and a year later got the first actual TV picture. In 1926, Baird showed TV in aLondonlaboratory. Two years later inNew York, Felix the Cat became the first TV star. TV excited everyone's imagination, but hardly anyone had a set, with just two thousand in use worldwide in the mid-1930s. Since the late 1940s, TV technology has developed very quickly. Computers may finally be combined with all televisions to give people a total all-in-one communications network. Today, it's possible to sit and watch TV in the middle of a forest or in the Arctic. It's surprising when one considers that Marconi was on Signal Hill in the same century.
Question: We can learn from the text that Signal Hill was once used as _ .
Options: (A) a site of communication (B) a weather station (C) a factory to produce weapons (D) a battle field to fight enemies from the outside
