Answer:

a. If the overall unemployment rate is 6 percent, teenage unemployment rates will exceed 12 percent.

Explanation:

Positive economics refers to the description of facts and information related to the economic situation of a country or region.

Here, the statement that if the overall unemployment rate is 6 percent, teenage unemployment rates will exceed 12 percent fulfills this criteria as it presents a simple and well-known fact that teenage unemployment rates are usually higher than the overall unemployment rate and can be double. This is because of a lack of skill set and experience at the youth level as compared to older age groups.
