Final answer:
Alex, who works part-time at a fast food restaurant, is considered employed according to the BLS criteria. Other individuals mentioned, without information on their work status, cannot be clearly categorized as employed, except for Bill, who is neither employed nor unemployed.
Step-by-step explanation:
When determining employment status, the Bureau of Labor Statistics (BLS) has specific criteria. Among the options provided, Alex, who works part-time at a fast food restaurant, is considered employed. Employment, according to the BLS's definition, includes all part-time and full-time workers who receive payment for their labor, regardless of the number of hours worked. Therefore, Alex fits into this category. On the other hand, Bill, who won the lottery and is enjoying leisure time, is not considered employed or unemployed because he is not actively working or seeking employment. Chris, who is actively looking for work in the manufacturing industry, is considered unemployed since he is without a job but is actively seeking employment. Lastly, David, who is a full-time student at the local university, falls into a special category. If David were working, say 12 hours a week at the college cafeteria, he would be considered employed, even though he is a student, as BLS counts students who work as part of the labor force. However, without additional information about David's work status, we cannot definitively categorize him.
Therefore, the correct answer to the question 'Who is considered employed among the following people?' is A. Alex, who works part-time at a fast food restaurant.
