• C)the OLS estimator is properly interpreted as a consistent estimator of the average causal effect in the population being studied.
• D)the TSLS estimator in general is not a consistent estimator of the average causal effect if an individual's decision to receive treatment depends on the effectiveness of the treatment for that individual.
