问题     Many parents across the country are getting a DNA sample just in case they need it if the youngster is kidnapped, runs away or suffers a terrible accident. News reports about child kidnapping and television shows such as " CSI: Crime Scene Investigation" are helping drive the interest in keeping genetic records that could be used to identify remains, hair or blood.

    "It’s the CSI mentality: that DNA is going to be the answer to any problem that comes up," said Jerry Nance, supervisor of the forensic assistance unit of the nonprofit National Center for Missing and Exploited Children. Missing kids found murdered or those who are never heard from make up only about 2 percent of the 850,000 kids who are reported missing every year, he said. Most children are found within several days or come home on their own.
    Despite those numbers, boxes are available that include a photo, fingerprints, a collection swab and a special envelope in which to put the DNA sample. The boxes are distributed by private companies, police stations, orthodontists and others. Most cost from $ 5 to $ 60, Nance said, but some are provided for free.
    Brian Wagner, police chief in Pleasant Prairie, Wis. , said his department created about 1,000 DNA collection boxes and began offering them for free in September. Parents have picked up more than 300. " We’ve been doing a lot of child fingerprinting, but that’s not always a reliable means of identification," Wagner said.
    Joe Polski, chief operations officer for the International Association for Identification, said he would not use the boxes but he would not discourage them. "The chances are so slim that it’s questionable in my mind if it’s worth the work to have it," he said.
    Craig Webre, first vice president of the National Sheriffs’ Association, said DNA collection could become standard within the next decade. He backs a new program called Kid ID, started by Bob Chastant, a dentist in New Iberia, La, who has collected DNA from kids since 1994 in his practice. He also encouraged dentists nationwide to join the program, in which the dentist takes a digital photograph of the child along with fingerprints. The items are entered into a Kid ID database. " It allows law enforcement to use the DNA for tracking where the child has been," Chastant said.
    Ed Smart said he wishes he would have known about the DNA boxes before his daughter Elizabeth was kidnapped from her Utah bedroom in June 2002. She was found alive nine months later. He said investigators took boxes of her belongings to find her DNA and did not get a sample back for weeks. Having the sample ready could have narrowed down suspects faster.
" It is kind of like an insurance policy you hope you never use," he said. [br] According to Jerry Nance, ______.

选项 A、DNA will be the answer to all the problems concerning missing children
B、DNA collection is of little use in finding missing children
C、children have the ability to find their way back home
D、the function of DNA in finding missing children is overstated

答案 D

解析 推理判断题。第二段首句中南斯指出:CSI带来了这样的心理,即: DNA是所有问题的答案。但是根据下文可知南斯并不同意这样的观点,所以选项[D]符合要求,为本题答案:[A]正是南斯反对的观点;[B]原文未提及;[C]不是南斯的观点。
