Question: Article: Cancer is feared by everyone. And there is more and more fear about cancer. Not the disease itself -- there is no such thing as a high incidence rates of cancer. Except for lung cancer, mostly caused by cigarette smoking, the incidence rates are not on the rise. However, some kinds of cancer are decreasing. But the fear of cancer is catching, and the country stands at risk of an anxiety. The earth itself is coming to seem like a huge carcinogen . The ordinary, more or less, scientific statement that something between 80 and 90 percent of all cancers are due to things in the environment is taken to mean that none of us will be safe until the whole environment is "cleaned up." This is not at all the meaning. The 80-percent calculation is based on the unthinkable differences in the incidence of cancer in various societies around the world -- for example, the high incidence of liver cancer in Africa and the Far East, stomach cancer in Japan, breast cancer in Western Europe and North America, and the relatively low figures for breast cancer in Japan and parts of Africa and for liver cancer in America. These data show there may be specific environmental influences, but largely based on personal life-style, which determines the incidence of various forms of cancer in different communities -- that is all the data suggest. The overall incidence of cancer, counting up all the cases, is probable roughly the same everywhere. Question: According to the passage, the incidence of cancer is generally believed _ . Yes or no, is the answer "to result from environmental influences"?
Answer: No

Question: 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"?
Answer: Yes
