Question: Read the article and select the best answer. Article: Scientists think it will be possible to record people's dreams and then interpret them, according to a new report. They claim to have developed a system which allows them to record higher level brain activity. Dr Moran Cerf told the journal Nature: "We would like to read people's dreams." Previously the only way to access people's dreams is for psychologists to ask about them after the event and try to interpret them. Dr Cerf hopes to eventually compare people's memories of their dreams with an electronic visualization of their brain activity. He told the BBC: "There's no clear answer as to why humans dream. And one of the questions we would like to answer is when do we actually create this dream?" The scientist believes his latest research shows that certain neurons or individual brain cells are linked with specific objects or concepts. He found that a particular neuron lit up when a volunteer thought about Marilyn Monroe. If a database was built up identifying various neurons with concepts, objects and people it would allow them to "read the subject's minds", according to Dr Cerf. However, Dr Roderick Oner, a clinical psychologist and dream expert, said that this kind of visualisation would be of limited help when it came to interpreting the "complex dream narrative". In addition to get a detailed picture of individual neurons subjects had to have electrodes implanted deep in the brain using surgery. The Nature researchers used data from patients who had electrodes implanted to monitor and treat them for brain seizures . However, Dr Cerf said he hoped that it would be possible at a later stage to monitor people without invasive surgery. He said it would be "wonderful" to be able to read the minds of _ patients who are unable to communicate. Question: What's the best title for this passage? Options: A: Scientists plan to record people's dreams B: Psychologists try to ask people about their dreams C: Dream experts want to interpret the complex dream narrative D: The Nature researchers intend to treat patients for brain seizures
Answer: A

Question: Read the article and select the best answer. Article: What doomed the Titanic is well known, at least in outline. On a moonless night of April 15, 1912, the ship hit an iceberg in the North Atlantic ,with 1,500 lives lost. A century later many people presented new theories to explain the real reason for the disaster. Now two new studies argue that rare states of nature played major roles in the disaster. The first says Earth's nearness to the Moon and the Sun -- a proximity not matched in more than 1,000 years -- resulted in record tides that help explain why the Titanic met with so much ice, including the fatal iceberg. Recently, a team of researchers found an apparent explanation in the heavens. They discovered that Earth had come unusually close to the Sun and Moon that winter, enhancing their gravitational pulls on the ocean and producing record tides. The rare orbits took place between December 1911 and February 1912 -- about two months before the disaster came about. The researchers suggest that the high tides refloated masses of icebergs traditionally stuck along the coastlines of Labrador and Newfoundland and sent them adrift into the North Atlantic shipping lanes. And a second, put forward by a Titanic historian from Britain, contends that the icy waters created ideal conditions for an unusual type of mirage that hid icebergs from lookouts whose duty was to watch carefully for danger ahead and confused a nearby ship as to the liner's identity, delaying rescue efforts for hours. Most people know mirages as natural phenomena caused when hot air near the Earth's surface bends light rays upward. In a desert, the effect prompts lost travelers to mistake patches of blue sky for pools of water. But another kind of mirage occurs when cold air bends light rays downward. In that case, observers can see objects and settings far over the horizon. The images often undergo quick distortions -- not unlike the wavy reflections in a funhouse mirror. Now, scholars of the Titanic are debating these new theories. Some have different opinions on it. Over all, though, many... Question: According to Theory Second, the disaster happened to the Titanic mainly because _ . Options: A: the freezing weather made the watcher not be able to watch clear B: the mirage on the sea attracted the watcher and made him forget his work C: the high tides drove the icebergs float so fast that the watcher didn't respond to them D: the mirage made the watcher not find icebergs and a nearby ship delay rescuing
Answer: D

Question: Read the article and select the best answer. Article: If you could leave a farewell video for your loved ones that they'd see only if you died, would you do it? I think I would. I read about an app that helps people create a video to be published on a social-networking site only after death. Of course you don't need an app since it's easy to make your own video with smartphones, laptops and computers. But how many people do you know who would actually go ahead and leave "If I die" footage ? My father died unexpectedly on Christmas Eve three years ago and I've since longed for one more time to talk to him and hear his voice. Imagine if he had left such a video. I would see him again, hear his laughter and benefit from his parting words and advice. I don't think people, unless they have a terminal illness, go through life thinking they'd better leave a video in case of an _ death. But it is an opportunity to say all the things you want to say before it's too late. Still, some say that such a video robs loved ones of their own memories of you. Any special images they have would be superimposed by the video image you've created. Others think it's scaring and might be tempting fate. I expect my video would consist of reminders to my children: Be safe; be[:++Z+X+X+K]mindful of your surroundings; exercise good judgment; speak up; it never hurts to ask; don't waste time and "call when you get there". And in addition, I would repeat what I always tell them: I need to know where you are, every-step-of-the-way. That would make them laugh. Readers, would you find comfort in knowing you've said your farewells and left something concrete for your loved ones? What messages would you leave for family and friends? Question: Some people against such a video argue that the image in the video _ . Options: A: will be different from that of the real person B: cannot convey the real intention of the dead C: will replace our loved ones' own memories of us D: will stop the loved ones from missing the dead
Answer:
C
