Explanation:

Question 1

The Tijuana River is located in the southwestern part of North America, near the border of Mexico and the US (California). The Pacific Ocean is on the west coast of North America, while the Atlantic Ocean, Caribbean Sea, and Gulf of Mexico are on the east/southern parts. The Tijuana River flows into the Pacific Ocean.

Aging sewage systems can leak or discharge untreated sewage, factories can release industrial waste, and farms can contribute runoff with pesticides/fertilizers. So all these sources contribute to pollution in the Tijuana River, making "All of the above" the correct choice.

Answer:

D. Pacific Ocean
