PROBLEM: Article: Many people cannot start their day without first having a cup of coffee or tea.These drinks help them think clearly and feel more awake.This is because of caffeine,which helps to give a jump start to the nervous system.Now,a report says it may also boost long-term memory. Mike Yassa is a neurobiology professor.He and other researchers wanted to know if caffeine could improve a person's memory.He explains,"After you learn anything,it takes some time for that memory to strengthen.And over the first 24 hours is actually where most of the forgetting happens.So that is where we wanted to intervene with caffeine and see if we can help reduce this forgetting." They took 160 caffeine-free people and showed them pictures of everyday objects. These people were asked if the objects could be found inside the house, or outdoors.Then some of the subjects were given a caffeine pill.The others were given a placebo--a pill containing nothing. 24 hours later,the subjects were shown the exact same images from the day before.They were also shown images with slight differences,and some completely new images. Both groups correctly identified the exact same and completely new pictures.But those who took the caffeine pill were better at spottingthe pictures that were slightly different. Professor Yassa says their answers helped to show the effects of caffeine on memory. And we find that if they are on caffeine they are much more likely to make the right decision." The amount of caffeine the researchers used in the study was similar to one cup of strong coffee.The researchers did not see any improvement to memory from smaller doses of caffeine or when it was given an hour before viewing the images.
Question: What is the focus of the text?

PROBLEM: Article: A great-grandfather has put up his Christmas tree for the 85thtime after his father first bought it from a toy shop. Douglas Hewitt, 85, has celebrated every Christmas with the artificial tree since he was born. His father bought the tree from a toy shop in Sheffield just months after Douglas was born. The four-foot tree remains the centre point of the Hewitt family household during every festive season. Mr. Hewitt, of South Anston, South Yorkshire, said, "It reminds us of my childhood, our children's childhood and our grandchildren and great-grandchildren's after that. They all come and look at it and smile; it's become part of the furniture. If we didn't put that Christmas tree up, it wouldn't feel like Christmas." The tree was passed down to Mr. Hewitt when he married Mavis. Mrs. Hewitt said, "Year after year we have just carried on using that one. You have to be a bit more careful with it now, as it's _ ." Their daughter, June Murphy, also has fond memories of the Christmas tree. She said, "It was in my grandparents' home and then it was given to us. It looks a little thin now, as each time you get it out something else falls off. It's become a bit of a family joke. Each year someone has to comment 'not again!' But it's a Christmas tradition of getting the tree out that we all love. We'd all be sad to see it go, as I think it would be hard to find such a loved replacement." Mr. Hewitt said, "There were a lot more branches on it, and it's lost its feathers that were all along the edge. There were little candle holders on the ends and little legs on it, but unfortunately they've been lost over the years."
Question: Where did Douglas Hewitt get the Christmas tree?
Options: (A) He got it from his father. (B) He bought it from a toy shop. (C) He made it by himself. (D) He cut it down in a forest.

PROBLEM: Article: Have you seen a historical film recently? Do you think it was accurate? Some say that there is no such thing as a historical film. In many cases, Hollywood film-makers simply change the facts. Just look at these supposedly "historical" films. 1. The Patriot The film was released in 2000 and was directed by Ronald Emmerish and starred Mel Gibson. It is set near Charleston, South Carolina, during the American Revolutionary War(1775--1783) and follows the story of Benjamin Martin and his fight for American freedom against the British. The film was criticized for inventing and exaggerating British cruelty. The most criticized scene was one showing the burning of a church containing people of the town, of which there is no historical record. Another historical inaccuracy was the description of American-owned slaves being freed to serve with the American forces. In reality, many slaves ran away from their American owners and fought with the British against the Americans. 2. Brave Heart The film(1995) starred Mel Gibson was directed by Toby Reisz. It is based on the life of Scottish national hero William Wallace and his fight against English rule in Scotland during the 13th century. The film includes an affair between William Wallace and Princess Isabella (based on Isabella of France). The film implies she is a mother-to-be when William Wallace will be killed. However, historically, the real Isabella was a child of nine still living in France at this time, never having met Wallace. The film also caused controversy because of its anti-English nature. Apparently, when the film was shown in Glasgow, there was a loud noise made by happy American audience. 3. U-571 This 2000 film was directed by Jonathan Mostow and starred Mathew MacConaughey, Havey Keitel and Jon Bon Jovi. It took place during the Second World War(1939--1945). In the film, a German submarine(warship underwater) is boarded in 1942 by American soldiers who made themselves up as Germans. They took away the German submarine's code-language machine, which, in the film, helps the Americans get many secret messages from Germany. However, the film was heavily criticized because it was actually the British who got the machine in May 1941 when they boarded U-110. The movie was also criticized for showing a scene where the U-boat sailors killed American sailors in the water after their ship sunk, which is, in 99% cases, impossible to happen. 4. The 300 Spartans The latest controversy surrounds the film The 300 Spartans. The film (directed by Zack Synder) tells the story of the battle between the Greeks and Persians in 480 BC. It is regarded as a key event in the birth of western democracy by some historians. In the film, 300 Spartans under the king fight against the enemies, 120,000 Persians led by Emperor Xerxes. The tiny Spartan forces repeatedly gain advantage over the invaders. These actions delays the Persians' attack and gives the Greek armies enough time to prepare for the defense of Athens. But the Iranians (modern-day Persians) aren't happy with the film. They say the film describes them as savage, killing-loving, and war-loving.
