No computer will ever be able to do everything that some human minds can do, for there are some problems that cannot be solved by following any set of mechanically applicable rules. Yet computers can only solve problems by following some set of mechanically applicable rules. Which one of the following is an assumption on which the argument depends
At least one problem solvable by following some set of mechanically applicable rules is not solvable by any human mind.
B. At least one problem not solvable by following any set of mechanically applicable rules is solvable by at least one human mind.
C. At least one problem solvable by following some set of mechanically applicable rules is solvable by every human mind.
D. Every problem that is solvable by following more than one set of mechanically applicable rules is solvable by almost every human mind.
Every problem that is solvable by following at least one set of mechanically applicable rules is solvable by at least one human mind.
Researchers have found that when very overweight people, who tend to have relatively low metabolic rates, lose weight primarily through dieting, their metabolisms generally remain unchanged. They will thus burn significantly fewer calories at the new weight then do people whose weight is normally at that level. Such newly thin persons will, therefore, ultimately regain weight until their body size again matches their metabolic rate. The conclusion of the argument above depends on which of the following assumptions
A. Relatively few very overweight people who have dieted down to a new weight tend to continue to consume substantially fewer calories than do people whose normal weight is at that level.
B. The metabolisms of people who are usually not overweight are much more able to vary than the metabolisms of people who have been very overweight.
C. The amount of calories that a person usually burns in a day is determined more by the amount that is consumed that day than by the current weight of the individual.
D. Researchers have not yet determined whether the metabolic rates of formerly very overweight individuals can be accelerated by means of chemical agents.
E. Because of the constancy of their metabolic rates, people who are at their usual weight normally have as much difficulty gaining weight as they do losing it.
