Answer: b. Lower rates of childhood asthma.
The text states that the treaty pledges a cap on industrial emissions and the development of renewable resource energy production. It does not state that this energy will come from wind farms, so we cannot assume that A is the answer. The statement also has no connection to vaccines, nor does it state anything about vitamin deficiencies. However, we do know that a consequence of industrial emissions is the development of respiratory problems on the population. Therefore, B is the best answer.
