　　Example：

　　Conclusion： I knew he did it.

　　Premise： Only a guilty person would accept immunity from prosecution.

　　The suppressed premise is that he did， in fact， accept immunity. The speaker　assumes that his audience is aware of this fact or at least is willing to believe it， so to state it would be redundant and ponderous. If the unstated　premise were false ， the argument would　not technically be a lie; but it would be very deceptive. The unscrupulous　writer may use this ploy if he thinks that he can get away with it. That is，his argument has the intended effect and the false premise， though implicit， is hard to find or is ambiguous. Politicians are not at all above using this tactic.

　　A common question on the GMAT asks you to find the suppressed premise of an　argument. Finding the suppressed premise， or assumption， of an argument can　be difficult. However， on the GMAT you have an advantage――the suppressed premise is listed as one of the five answer-choices. To test whether an answer-choice is a suppressed premise， ask yourself whether it would make the argument more plausible. If so， then it is very likely a suppressed premise.

　　Example：

　　American attitudes tend to be rather insular， but there is much we can learn　from other countries. In Japan， for example， workers set aside some time each day to exercise， and many corporations provide elaborate exercise facilities for their employees. Few American corporations have such exercise programs. Studies have shown that the Japanese worker is more productive than the　American worker. Thus it must be concluded that the productivity of American　workers will lag behind their Japanese counterparts， until mandatory exercise programs are introduced.
