Question

a problem solving method that involves trying all possible solutions until one works is using _______
a. an algorithm
b. trial-and-error
c. deductive reasoning
d. a heuristic

please select the best answer from the choices provided

a
b
c
d

Explanation:

Define the problem-solving method described

The question describes a method of trying all possible solutions sequentially until one succeeds. This is the definition of trial-and-error.

Compare with other options

• An algorithm is a step-by-step, systematic procedure that guarantees a correct solution.
• Deductive reasoning is a top-down logical process of drawing specific conclusions from general premises.
• A heuristic is a mental shortcut or "rule of thumb" used to make quick decisions, which does not guarantee a solution.

Select the correct option

The description matches option B, trial-and-error.

Answer:

• (A) an algorithm
• (B) trial-and-error (Correct answer)
• (C) deductive reasoning
• (D) a heuristic
