    From the passage, it can be concluded that . A. old people are always right B. old people are wiser than the young C. young people shouldn’t regard old ideas as useless or out of date sometimes D. young people usually have different opinions from the old E A study published in September suggests there is a surprising way to get people to avoid unhealthy foods: change their memories. Scientist Elizabeth Loftus of the University of California at Irvine asked volunteers to answer some questions on their personalitiesand food experiences. “One week later, Loftus says, “we told those people we’d fed their answers into our smart computer and it came up with an account of their early childhood experiences. Some accounts included one key additional detail. “You got sick after eating strawberry ice-cream. The researchers then changed this detail into a manufacturedmemory through leading questions --- Who were you with? How did you feel? By the end of the study, up to 41% of those given a false memory believed strawberry ice-cream once made them sick, and many said they’d avoid eating it. When Loftus published her findings, she started getting calls from people begging her to make them remember hating chocolate or French fries. Unfortunately, it’s not that easy. False memories appear to work only for foods you don’t eat on a regular basis. But most important, it is likely that false memories can be implantedonly in people who are unaware of the mental control. And lying to a patient is immoral, even if a doctor believes it’s for the patient’s benefit. Loftus says there’s nothing to stop parents from trying it with their overweight children. “I say, wake up --- parents have been lying about Father Christmas for years, and nobody seems to mind. If they can prevent diseases caused by fatness and all the other problems that come with that, you might think that’s more moral lie. Decide that for yourself. 【查看更多】

         A story tells that a senior villager led some other villagers carrying salt day and night to a town in order to
    trade rice as food the winter. One night they camped in a wilderness with a starry sky above. The senior
    villager, obeying the tradition passed down from forefathers, took out three blocks of salt and threw them into
    the campfire, probably to predict the changes of weather in the mountains.
         All eagerly waited for the old man's" weather report":if the salt in the fire produced crackling sound, they
    would have good weather in store；if no sound was produced, it then meant the good weather would soon end
    and a storm would come at any moment.
         The senior villager looked serious. The salt in the campfire made no sound at all. Convinced by this bad
    sign, he urged (催促) the whole team to set out immediately after daybreak. A young man in the group,
    however, insisted that they should not start in such a hurry, considering it superstitious to" forecast weather by
    using salt.
         It was not until the next afternoon that the young man caught up on the wisdom of the old man when the
    weather suddenly changed, with cold winds blowing and a snowstorm raging. In fact, the method used by the
    clan head could be well explained by modem science:whether or not salt produces sound in campfire depends
    on air humidity (湿度).That is to say, when a storm approaches, due to high humidity, the dampened salt
    blocks will not produce any sound in fire.
