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.
Linkage to conclusion : 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.
The argument makes a prediction that computer models won't be accurate to predict market behaviors.
The given fact to support the conclusion is no known technology that can make a computer fast enough to perform all of the necessary computations,
and 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.
The assumption to arrive at the conclusion is :
1) Only technology can
empower the computers/supercomputers to process the huge amounts of data.
2) There is no existing technology in the present /future that can help supercomputers
Only choice B is correct here in light of this assumption.
