Which of the following best completes the passage below?

In a survey of job applicants, two-fifths a little admitted to being at least dishonest. However, the survey may underestimate the proportion of job applicants who are dishonest, because ________.

Given, 

In a survey of job applicants, two-fifths a little admitted to being at least dishonest. However, the survey may underestimate the proportion of job applicants who are dishonest, because ________.

Now,

Option - I: Details: The passage states that the survey may underestimate the proportion of dishonest job applicants.

This implies that the actual number of dishonest people is likely higher than what the survey revealed. Fulfillment:

Yes, this is the core premise of the question.

Options 2, 3, and 4 do not support the idea of underestimation:

• Option 2 (honest people claiming dishonesty) would lead to an overestimation.
• Option 3 (some dishonesty implying greater dishonesty) doesn't change the number of admitted dishonest individuals, just the degree.
• Option 4 (dishonest people answering honestly) means the survey accurately captured those individuals, not an underestimation.

Therefore, the most logical reason for the survey to underestimate the proportion of dishonest job applicants is that dishonest individuals might lie on the survey and claim to be honest.

Hence, the correct answer is "Option 1"( some dishonest people taking the survey might have claimed on the survey to be honest".)
