Determine whether each statement is true, false, or uncertain and explain why.

a). In 2021, the Biden administration and the democratic congress attempted to increase the tax rate on realized capital gains of high earners starting in 2022. However, they failed to pass anything. Therefore, we should observe no impact of this tax policy debate on realized capital gains.
