We learn to use most of the machines in our lives through written instructions, without knowledge of the machines'inner workings, because most machines are specifically designed for use by nonexperts. So, in general, attaining technological expertise would prepare students for tomorrow's job market no better than would a more traditional education stressing verbal and quantitative skills.
The argument depends on assuming which one of the following? - We need to find a minimum condition or a missing premise
A) Fewer people receive a traditional education stressing verbal and quantitative skills now than did 20 years ago. - Irrelevant
B) Facility in operating machines designed for use by nonexperts is almost never enhanced by expert knowledge of the machines' inner workings. - "facility" means "ability." It means "ability is never enhanced" - out of scope.
C) Most jobs in tomorrow's job market will not demand the ability to operate many machines that are designed for use only by experts. - if we negate it, it'll shatter the conclusion. Ok.
D) Students cannot attain technological expertise and also receive an education that does not neglect verbal and quantitative skills. - irrelevant
E) When learning to use a machine, technological expertise is never more important than verbal and quantitative skills. - this comparison is out of scope.
