Question

which of the following statements best supports the argument regarding human activities and their influence on atmospheric composition?

○ human activities, such as using aerosol sprays and air conditioning, have been shown to add beneficial gases to the atmosphere.

○ human activities, such as deforestation, have minimal impact on atmospheric composition

○ human activities, such as burning fossil fuels, release large amounts of carbon dioxide into the atmosphere.

○ human activities, such as burning fossil fuels, only alter atmospheric composition locally, and have no impact on a global scale.

Explanation:

La pregunta busca una afirmación que apoye la influencia de las actividades humanas en la composición atmosférica. Las actividades como la quema de combustibles fósiles liberan grandes cantidades de dióxido de carbono, un gas que modifica la composición atmosférica (ej. efecto invernadero). Las otras opciones son incorrectas: el uso de aerosoles y AC no añade gases beneficiosos, la deforestación tiene impacto significativo, y la quema de combustibles fósiles afecta globalmente.

Answer:

C. Human activities, such as burning fossil fuels, release large amounts of carbon dioxide into the atmosphere.
