Final answer:
Black teens have historically faced higher unemployment rates than other ethnic groups, which has decreased since the 1990s but rose again during the Great Recession. The correct answer is a) True.
Step-by-step explanation:
The question concerns whether it is true that Black teens have the highest rate of unemployment of all ethnic groups. According to various sources, including historical data from the Bureau of Labor Statistics (BLS), while the unemployment rate for African-Americans has often been substantially higher compared to other racial or ethnic groups, unemployment trends are affected by different economic periods.
In particular, the gaps between unemployment rates for White, Black, and Hispanic people have diminished since the 1990s. There was a period in the mid-2000s when unemployment for Black and Hispanic individuals was at its lowest level in several decades, although these rates did rise during the Great Recession. Therefore, the correct answer is a) True.
