The correct answer is True.

Explanation

When we must solve a multiple-choice test or exam, in most cases, we are asked to select only one choice from four or more options. This means we need to know which is the correct answer from the options given to obtain a good grade. Due to this, we must be very precise when responding and paying attention to details because many times the answers are very similar, but only one contains all the elements that answer the question.

One of the most used methods to do this is "eliminating answers" this means we discard answers that we are sure are not possible answers by crossing out these and leaving only the correct answer or a few possible correct answers, in this case, we will need to analyze the remaining answers to select the most appropriate. So, the correct answer is True.
