Logic Breakdown
Passage Summary: Humans become experts by experiencing many situations until they can just 'know' what to do instinctively, whereas computers just follow rules and data, so they can't reach that same level of expertise.
Conclusion: Computerized "expert systems" will never match the quality of human experts.
Reasoning: Expertise requires an intuitive response built through experience, and unlike computers which store data as rules and facts, human experts do not store their knowledge in that format.
Analysis: The argument hinges on a gap between the method of storing information and the ability to perform a task. The author assumes that because a computer's 'brain' works differently than a human's (rules vs. non-rules), it cannot produce the same 'intuitive' result. To find the necessary assumption, ask what must be true for the conclusion to hold: the argument requires that a system based on rules and facts is fundamentally incapable of mimicking or achieving human-level intuition.

Unlock Full Passage6.The argument requires the assumption of which one of the following?
Correct Answer
B
B is necessary. If the knowledge of human experts could be adequately rendered into the type of information a computer can store, then computers could implement that repertory of model situations and intuitive responses. Negation test: If human expert knowledge can be adequately rendered for computers, the conclusion that expert systems cannot be as good collapses. Therefore B is required.
