Therapeutic Touch

A nine-year-old schoolgirl single-handedly cooks up a science-fair equipment that ends up debunking a widely practiced medical treatment.Emily Rosa's target was a practice known as therapeutic touch(TF for short),whose advocates manipulate patients'"energy field"to make them feel better and even,say some,to cure them of various ills.Yet Emily's test shows that these energy fields can't be detected,even by trained TT practitioners.Obviously mindful of the publicity value of the situation,Journal editor George Lundberg appeared on TV to declare,"Age doesn't matter. It's good science that matters,and this is good science."
Emily's mother Linda Rosa,a registered nurse,has been campaigning against TT for nearly a decade.Linda first thought about TT in the late 80s,when she learned it was on the approval list for continuing nursing deduction in Colorado.Its 100,000 trained practitioners(48,000 in the U.S.)don't even touch their patients.Instead they waved their hands a few inches from the patient's body, pushing energy fields around until they are in"balance"．竹advocates say these manipulations can help heal wounds,relative pain and reduce fever. The claims are taken seriously enough that竹 therapists are frequently hired by leading hospitals,at up to $70 an hour,to smooth patients' energy,sometimes during surgery.
Yet Rosa cold not find any evidence that it works.To provide such proof,TT therapists would have to sit down for independent testing一something they haven't been eager to do,even though James Randi has offered more than $1 million to anyone who can demonstrate the existence of a human energy field.(He has had one taker so far. She failed.)A skeptic might conclude that TT practitioners are afraid to lay their beliefs on the line.But who could turn down an innocent forth-grader? Says Emily:"I think they didn't take me very seriously because I am a kid."
The experiment was straightforward;21 Ti' therapists stuck their hands,palms up,through a screen.Emily held her own hand over one of their left or right一and the practitioners had to say which hand it was.When the results were recorded,they had done no better than they would have by simply guessing. If there was an energy field,they wouldn't feel it. The purpose of Emily Rosa's experiment was______.
A.to see why TT could work the way it did
B.to find out how TT cured patients' illnesses
C.to test whether she could sense the human energy field
D.to test whether a human energy field really existed
