Interviewer: A certain company released a model of computer whose microprocessor design was flawed, making that computer liable to process information incorrectly. How did this happen? Industry spokesperson: Given the huge number of circuits in the microprocessor of any modern computer, not every circuit can be manually checked before a computer model that contains the microprocessor is released. Interviewer: Then what guarantee do we have that new microprocessors will not be similarly flawed? Industry spokesperson: There is no chance of further microprocessor design flaws, since all microprocessors are now entirely computer-designed. The industry spokesperson's argument is most vulnerable to criticism on the grounds that it ['ignores the possibility that a microprocessor can have a flaw other than a design flaw', 'overlooks the possibility that a new computer model is liable to malfunction for reasons other than a microprocessor flaw', 'takes for granted, despite evidence to the contrary, that some computers are not liable to error', 'presumes, without providing justification, that the microprocessor quality-control procedures of the company mentioned are not representative of those followed throughout the industry']
