Extrapolating from the adage "two heads are better than one", a group of economists at the University of Iowa has learned how to turn the instincts of individuals into useful predictions of the future. So far, the researchers have tested their method by predicting the outcome of such events as the American presidential election and the number of books sold on the first day of a Harry Potter re lease. Now, they have turned their sights to influenza.
The influenza in question is not the pandemic bird-flu-related sort that is currently a cause for concern but the quotidian bug that lays people low, particularly in winter. Even this disease is not trivial, it kills, for instance, about 36, 000 people in America and possibly as many as 12, 000 people in Britain every year. If outbreaks could be predicted, patients at particular risk could be vaccinated and medical personnel redeployed in anticipation. $o Philip Polgreen and his colleagues wonder
A. cure the bird-flu disease.
B. cure influenza.
C. give adequate help to patients.
D. anticipate the outbreaks of flu.
