Article: When a consumer finds that something he or she bought is faulty or in some other way does not live up to what the producer says for it, the first step is to present the warranty ,or any other records that might help, at the store of buying. In most cases, this action will produce results. However, if it does not, there are various means the consumer may use to gain satisfaction.A simple and common method used by many consumers is to complain directly to the store manager. In general, the "higher up" the consumer takes his or her complaint, the faster he or she can expect it to be settled. In such a case, it is usually settled in the consumer's favour, taking it as true that he or she has a just right. Consumers should complain in person whenever possible, but if they cannot get to the place of buying, it is acceptable to phone or write the complaint in a letter. Complaining is usually most effective when it is done politely but firmly, and especially when the consumer can show clearly what is wrong with what was bought in question. If this cannot be done, the consumer will succeed best by presenting specific information as to what is wrong, rather than by making general statements. For example,"The left speaker does not work at all and the sound coming out of the right one is unclear" is better than "This stereo does not work.". The store manager may advise the consumer to write to the producer, if so, the consumer should do this, stating the complaint as politely and as firmly as possible. But if a polite complaint does not achieve the expected result, the consumer can go a step further. He or she can threaten to take the seller to court or report the seller to a public organization responsible for protecting consumers' rights. Question: According to the passage, the last way a consumer has to use is _ Yes or no, is the answer "to warn the seller to turn to the court or a public organization for help"?
Yes

Article: Air traffic controllers in the US have been advised to take 26-minute naps , after a series of accidents involving workers falling asleep. Now the National Transportation Safety Board (NTSB) is calling for "controlled naps" during nightshifts . NTSB member Mark Rosekind said that a 26-minute nap would improve performance by 34%. He believes that beyond the aviation industry, other professions, such as motoring and machinery, also carry obvious risks. But other experts doubt whether 26 minutes is the appropriate napping time. It's a bit too long and risks you falling into a deep sleep, says Jim Horne, director of the Sleep Research Council. He said, "A nap of about 15 minutes is best; once you get beyond 20 minutes, you risk a deep sleep and you can be much more tired when you wake up. Therefore, we suggest that a nap be combined with a cup of coffee so that you can enjoy an effective sleep before the caffeine takes effect in 20 minutes. However, this method only works on those who have had a poor night's sleep. If you haven't had a sleep the night before, this method won't be enough to make you fresh." Health writer, Linda Wasmer Andrews, also believes that 26 minutes is too long. She says a nap between 10 and 20 minutes is enough, and the timing of the nap is also important. Putting your head down too early means your body may not be ready to sleep yet, but a nap that is too late in a day might make it harder to fall asleep. Early afternoon is often the best time, between l pm to 3pm, when people experience a post-lunch decrease in energy. Question: What does the text mainly talk about? Yes or no, is the answer "How long a nap should last."?
(Answer)
Yes

Ques: Article: Most people, when they travel to space, would like to stay in orbit for a few days of more. And this stands to reason, if you' re paying $20,000 for your trip to orbit! Strain order for tourism to reach its full potential there' s going to be a need for orbital accommodation--or space hotels. What would a space hotel actually be like to visit? Hotels in orbit will offer the services you expect from a hotel--private rooms, meals, bars. But they' ll also offer two unique experiences: impressive views--of Earth and space--and the endless entertainment of living in zero gravity--including sports and other activities that make use of this. The hotels themselves will vary greatly--from being quite simple in the early days to huge luxury structure at a later date. It s actually surprising that as later as 1997, very few designs for space hotels were published. This is mainly because those who might be expected to design them haven' t expected launch costs to come down far enough to make them possible. Lots of people who' ve been to space have described vividly what it' s like to live in zero gravity. There are obviously all sort of possibilities for dancing, gymnastics, and zero-G sports. Luckily, you don' t need to sleep much living in zero gravity, so you' ll have plenty of time for relaxing by hanging out in a bar with a window looking down at the turning Earth below. Of course all good things have come to an end. Unfortunately, and so after a few days you' ll find yourself heading back enough you' ll be much more expert at exercising in zero gravity than you were when you arrived. You' ll be thinking how soon you can save up enough to get back up again--or maybe you should change jobs to get to work in an orbiting hotel. Question: When traveling in space, most people would like to stay in orbi t for a few days because _ . Yes or no, is the answer "It is expensive to travel in space"?
Ans: No

Ques:Article: Before the opening of the Cape Cod Canal in 1914,the only way ships could leave Boston was on a route around Race Point--the northern tip of Cape Cod.However,navigation during the 18th century was a nightmare,because the floating cross current around Race Point caused countless accidents.So building a lighthouse to lighten the place was very necessary. As early as 1808,the people of Provincetown requested a lighthouse on Race Point,but it took Congress eight years to react when they finally paid $ 8,000 on April 27,1816 to build a lighthouse --Race Point Light,which was located in the town of Provincetown,Massachusetts.It was first built of stone 25 feet high with no foundation and its light was 30 feet above the sea.It was equipped with one of the nation's earliest revolving lights. Actually,there were two other lighthouses on Cape Cod,but they were hit by a storm in October 1841.In the following year,Race Point Light was examined by I.W.P.Lewis,who realized the light's importance.He said,"The light should be useful to all ships leaving Boston.However,its _ power is so weak that people would hardly be able to differentiate it from the lights set on the ships which stay in the bay,or close by.It hasn't played its role as a lighthouse well." The result was that old lighthouse was destroyed and a new iron lighthouse with a proper foundation was put up to take its place.The new lighthouse was 45 feet high.Although the original keeper's house was in good repair,it was destroyed too and a new one was built.Today the lighthouse has been automated and Race Point Light is still an active aid to navigation. You can park at Race Point Beach and walk about 45 minutes to the lighthouse.Sunset at Race Point Light is one of the Cape Cod's most popular scenes.And at times whales can be seen in the lighthouse.For reservations to stay one night in the keeper's house at Race Point call(508)487-9930. Question: According to the passage,Race Point Light _ . Yes or no, is the answer "is also a tourist spot now"?

Ans:
