A.I. Explanation:

Option 1: "Highly educated individuals"

Explanation: This option is incorrect because the text explicitly states that the lower class is composed primarily of the displaced poor who have little formal education. Therefore, the presence of highly educated individuals in the lower class contradicts the information provided.

Option 2: "Individuals with stable, high-paying jobs"

Explanation: This option is incorrect as it contradicts the text, which describes the lower class as having individuals who are often unemployed or working in minimum-wage jobs. Stable, high-paying jobs are not characteristic of the lower class.

Option 3: "The underclass, who may rely on public assistance or illegal activities"

Explanation: While the text mentions the underclass, it states that the underclass is a separate group that has been added to the lower class. Therefore, this option does not accurately describe the lower class itself, making it incorrect.

Option 4: "People often working in minimum-wage jobs"

Explanation: This option is correct because the text clearly states that people in the lower class are often working in minimum-wage jobs. This aligns directly with the description of the lower class.

Option 5: "A large portion of working poor"

Explanation: This option is correct as the text indicates that the working poor constitute a large portion of those who are poor. This directly supports the idea that the lower class includes a significant number of working poor individuals.
