Civil trials often involve great complexities that are beyond the capacities of jurors to understand. As a result, jurors’ decisions in such trials are frequently incorrect. Justice would therefore be better served if the more complex trials were decided by judges rather than juries.
The argument above depends on which of the following assumptions

A．A majority of civil trials involve complexities that jurors are not capable of understanding.

B．The judges who would decide complex civil trials would be better able to understand the complexities of those trials than jurors are.

C．The judges who would preside over civil trials would disallow the most complex sorts of evidence from being introduced into those trials.

D．Jurors’ decisions are frequently incorrect even in those civil trials that do not involve great complexities.

E．(E) The sole reason in favor of having juries decide civil trials is the supposition that their decisions will almost always be correct.
