Answer:
Un problema ambiental es un cambio que ha tenido lugar o se está produciendo en el medio ambiente que una persona encuentra problemático por alguna razón. Normalmente, solo los cambios provocados por el hombre se consideran problemas ambientales: los desastres naturales como terremotos o tormentas, por ejemplo, generalmente no se consideran problemas ambientales. Los problemas ambientales actuales a menudo se consideran relacionados, entre otras cosas, con el consumo excesivo y la superpoblación, el agotamiento de los recursos, la industrialización, la desigualdad y la pobreza, la ignorancia o la tecnología subdesarrollada.
Los fenómenos comunes considerados problemas ambientales incluyen el cambio climático, la eutrofización, el agotamiento del ozono, la erosión, la acidificación del suelo y el agua, la contaminación ambiental y el agotamiento de la biodiversidad, por ejemplo en forma de extinciones de especies.

<u> A. Most PACs associated with interest groups can only collect funds from group members.</u>
<u>The Political Action Committees (PAC) can only raise money through members' donations; the members generally consist of corporations, labor unions, trade associations, other types of organizations, and individuals.</u>

D. is incorrect as well as $5000 is not the minimum amount they can donate, in fact, it is the maximum.

And they can receive up to $5,000 from any one individual, PAC or party committee per year.
