Economic modeling programs used to predict the future trends of financial markets are notoriously unreliable, primarily because of the enormous number of variables that affect the behavior of investors. No computer, even the most powerful and sophisticated supercomputer, is capable of processing the huge amounts of data necessary for even very short-term forecasts. Because there is no known technology that can make a computer fast enough to perform all of the necessary computations, computer models will never be accurate enough to predict market behavior reliably.
Which of the following, if true, most weakens the argument’s prediction?
A. Over the past five decades, the processing capacity of computers has doubled every two years on average.
B. Complex programs can be subdivided and distributed over multiple interconnected computers that work together to perform extremely large numbers of computations.
C. Banks and financial institutions have relied on computers for decades to track market fluctuations and trends for planning purposes.
D. The use of complexity theory has helped economists to create the most accurate models to date for predicting market crashes.
E. Modeling programs run on supercomputers are used by central banks throughout the world to assist in the formulation of national monetary policies.
