Article: Drinking a lot of water does not do any good to the body, according to two experts in the United States. In fact, they warn, drinking too much water could be, in certain cases, harmful. In a study, Dr Stanly Goldfarb and Dr Dan Negoianu, both of the Renal, Electrolyte and Hypertension Division at the University of Pensylvania, the United States, have denied the popular belief that drinking a lot of water clears body toxins better, improves skin, and helps reduce weight. Dr Goldfarb and Dr Negoianu say that they found little proof to back the public opinion that drinking 8 glasses of water every day benefits health. At the same time, they fond little proof of harm in drinking 8 glasses of water every day. It is widely believed that in some cases-such as athletes, people who live in hot, dry environments, and those with certain medical conditions-drinking a lot of water indeed helps, but no studies have been done to prove the benefits of this practice in average, healthy people, the website medheadlines.com reports. The study at the University of Pennsylvania also examined reports that some people experienced increased headaches when their consumption of water was low. In one small study, which the doctors reviewed, the group drinking the most water reported fewer headaches than the control group, "but the difference in the number of headaches was o small between the two groups as to be considered unimportant." The researchers concluded that there is no scientific proof to support that average, healthy people need to drink at least 8 glasses of water each each day. The website medheadines.com says that, according to an Indian doctor, drinking too much water is harmful. If water enters the body more quickly than it can be removed, problems can occur. Question: According to the passage, we know that _ . Yes or no, is the answer "the two experts performed the study at the University of Pennsylvania"?
No

Article: If you try to explain to someone, without using pictures, how to build the building that you have designed, it would take an enormous amount of writing and might end up with a very funny-looking building. The architect uses pictures called details to show how many hundreds of parts go together to form a complete building. This type of drawing is called drafting and is done by people called draftsmen. Draftsmen make up the largest group of the architectural offices' work force. Because of the wide range of duties they perform, draftsmen are sometimes called architectural technicians. In a typical office, there are not only career draftsmen but also architectural graduates working as junior draftsmen to learn the trade. Career draftsmen are usually graduates from a two-year junior college called technical school. There was a time when architectural office used young people right out of high school as tracers. Their job was to trace over the other people's details while learning to be a draftsman. This is no longer possible with the fast-pace of architects' offices today although a junior draftsman is given guides by the more experienced employees. So a good comprehensive architectural drafting course is a must before anyone seeks a job with an architectural firm. The job of the draftsmen is to translate the ideas and directions of architects, designers and engineers into complete and accurate working drawings. These become the plans and details used in the actual construction of a building. The project must be shown in great detail and drawn very clearly, so there is no chance for misunderstanding by the contractors . Every line and figure has an effect on the finished product. As you can see, the draftsman is a key member of the architectural team. Of course, a junior draftsman is not expected to produce a complete set of working drawings. Depending on the size of the office and difficulty of the project, draftsmen may work in groups. The group leader coordinates the group and works closely with the... Question: What is most essential for draftsmen's work according to the author? Yes or no, is the answer "Accuracy in the drawings."?
No

Q: Article: While many modern forms of communication like phone calls, e-mail, and letters, are extremely convenient. In my opinion, nothing beats speaking to another person face to face. The first and most obvious advantage that a face communication has over a letter and e-mail is that there is the ability to interactively converse. If the sender of a letter or an email does not write clearly, then much time must be spent to clear up the misunderstanding. In a face-to-face conversation, misunderstandings are easily dealt with because of the interactive nature of it. I would still argue that the face-to-face conversation is better because you can see the other person. Not all communication is verbal ; the meaning of much of what we say depends on our body language and the tone of voice. Joking and irony are particularly difficult to express and enjoy without seeing the expression on someone's face, or watching the movements of their body. Finally, if the goal of communication is to maintain or deepen the relationship with someone, the face-to-face communication offers the choice of communication by touch even if we could communicate by the video. Trust and respect between business partners can be established with a firm handshake. No amount of body language can convey the excitement of a high five between friends, and no number of words can communicate the comforting embrace of a loved one. Touch is the first basic method of our human relationships, before spoken language, and it is only available when people communicate face to face. Question: The author's attitude towards forms of communication is_. Yes or no, is the answer "Face-to-face communication has advantages over the other ways of communication."?
A: No

Article: Humans have observed and explored the oceans since ancient times.But it wasn't until the 19th century that the scientific study of oceans began.The first major scientific expedition,and the one that firmly established the field of oceanography,was the around-the-world voyage of H.M.S. Challenger.Setting out from England in 1872,the Challenger spent almost three and a half years gathering a wealth of information about seawater,sea life,and the ocean floor.Major oceanographic expeditions since then have included the South Atlantic voyage of the German ship Meteor in 1926 and the Deep-Sea Drilling Project from 1968 to 1983.Many individuals also have played important roles in advancing our understanding of oceans,beginning with Matthew Fontaine Maury in the mid-1800s;his work on oceanography and navigation led to a uniform system of weather reporting at sea.Since Maury's time,oceanography has progressed rapidly.Early oceanographers had to contend themselves with tossing buckets overboard to see what they might haul in.Today's oceanographers are equipped with space images,supercomputer models,and deep-sea robots that can crawl along the seafloor.As they set goals for the future,some oceanographers even dream of doing research in permanently manned stations on the bottom of the oceans. Question: Which of the following statements is true? Yes or no, is the answer "Many individuals also plays a very important part in advancing our understanding of oceans,such as Maury."?
**Answer**
No
