It began as just another research project, in this case to examine the effects of various drugs on patients with a severe mood disorder. Using an advanced brain scanning technology—the clumsily named echo-planar magnetic resonance spectroscopic imaging(磁共振光谱现象) procedure, or EP-MRSI—researchers at Boston’s McLean Hospital scanned the medicated and unmedicated brains of 30 people with bipolar disorder in order to detect possible new treatments for the more than 2 million American adults who suffer from the disease.
But something unexpected happened. A patient who had been so depressed and could barely speak became ebullient after the 45-minute brain scan. Then a second patient, who seemed incapable of even a smile, emerged actually telling jokes. Then another and another. Was this some coincidence Aimee Parow, the technician who made these observations (she is now a medical student in New York) didn’t think so. She mentioned the pat

[单项选择]A detailed and thorough research project undertaken by the Open University recently reported that their evidence appears to show that competition between nearby schools does not significantly improve academic standards. Indeed, their report inclines to the opposite outcome: the exam results may actually decline where competition is fiercest.
When the further education sector was "privatized" a few years ago, competition between colleges became truly fierce, at least in urban areas where potential students could choose between several of them. Colleges appointed highly paid marketing directors and gave them large budgets; some even "bribed" interested students with promises of hundreds of pounds if they completed certain courses satisfactorily.
Fully competitive markets being a philosophical foundation of Britain’s recent governments, it was no surprise to hear claims that many educational developments of the 1990s would move us towards a free market in secondary education--gi
A. higher enrollment rate
B. lower academic standard
C. higher marketing expenses
D. privatization of further education
