Read the article and select the best answer. Article: Noise pollution in cities is causing out health to suffer, according to the World Health Organization. Recently, researchers at the Free University of Brussels in Beigium have developed an applocation: NoiseTube. It allows everyone who downloads it the ability to measure the amount of noise they are exposed to by transforming their smart phone into a sound level meter. NoiseTube works by recording sound levels and GPS locations. Once launched the app shows decibel levels of green or red depending on the level of noise. That information is then sent to the NoiseTube server via the Internet where a "noise map" is produced and then made available to the user. Since its launch, the app has been popular with community groups who want to monitor their own noise levels. According to D'hondt of the Noise Tube project, these groups don't think that city produced noise maps give an adequate interpretation of the level of noise they're experiencing. City produced noise maps are based on statistical models involving very few actual measurements. NoiseTube on the other hand gives a detailed account of the level of noise experienced at a specific time and location. "Ten people walking the same area from 9 to 10 am every day for one week can make a valid and detailed map for an area of a couple of blocks," D'Hondt said. "It's reasonable effort by the community groups to produce these maps, and with it they can go to the authorities and have real evidence about what they're experiencing." So far these sorts of noise maps have been produced for a number of European cities. The app has been downloaded by 10,000 people with 2,700 people registered on the NoiseTube website. Question: The reliability of city produced noise maps is questionable because _ . Options: A: the research is based on only a few actual measurements B: they can only be used at a specific time and location C: their operating principles are not clear D: the collected information isn't enough to prove it

Q: Read the article and select the best answer. Article: Body language is a very powerful tool of communication, not only between people but in the animal world as well. In many instances, we produce idioms (,)which are all understandable by borrowing examples from animal communication. For example, we know that a frightened cat will arch its back high in rigid curve . From this starting-point we might hear the expression, "He gets my back up!" meaning "He makes me angry." In the same manner, we know that many animals, if challenged by attackers, will not turn and run away because this will encourage the attacker to attack them more forcefully. Instead, they will move backwards slowly to get out of harm's way, always still facing their attacker.We call this action " _ " and it can be used just as well with humans as with animals. In the case of humans, however, the back-off may not be physical but oral, as in using a kinder tone of voice and gentler words instead of fighting against the attackers. Question: Which of the following is NOT true according to the text? Options: A: To learn knowledge, humans must learn from animals. B: Both humans and animals have body languages. C: Both humans and animals have ways of escaping from danger. D: "Backing off " means keeping away from your enemies.
A: A
