Final answer:
Tatiana would be counted as unemployed by the Bureau of Labor Statistics, as she is likely available for and possibly seeking work after being laid off. Ivan would not be counted as unemployed since he has not actively looked for work in the last two months.
Step-by-step explanation:
The U.S. Bureau of Labor Statistics (BLS) defines unemployed individuals as those who are without a job, currently available to work, and who have actively looked for work in the previous four weeks. Given this definition, Tatiana, who is waiting to be recalled to a job from which she was laid off, is likely to be currently available for work and possibly actively looking for work, hence she is counted as unemployed. Ivan, on the other hand, was fired and has not looked for work during the last two months; he would be classified as not in the labor force because he is not actively looking for work. Therefore, the correct answer is c. Tatiana but not Ivan.
