b. it is a partial list of endangered species
c. it only includes species in north america
d. it updates automatically when species become endangered

Explanation:

For question 5:

• Oil tanker accidents are a significant source of crude oil pollution in ocean waters. While natural seepage occurs, it is not the primary anthropogenic source. Offshore drilling operations have safeguards and industrial waste discharge is not the main source of crude - oil (specifically) in ocean waters compared to tanker accidents.

For question 6:

• The Endangered Species Act (ESA) in the US is a partial list. It does not include every endangered species on Earth (as it is a US - based act). It is not limited to North American species (it can list non - North American species that are relevant to the US ecosystem in some way, like migratory species). And it does not update automatically; there is a process involving scientific review and potential listing or delisting.

Answer:

1. A. Oil tanker accidents
2. B. It is a partial list of endangered species
