Explanation:

Analyze context clues in paragraph 11

The sentence states that "the most highly polluted water, such as shampoo rinse, is jettisoned and replaced." The word "replaced" indicates that the old, polluted water is removed or thrown away so that new, clean water can take its place.

Evaluate the answer choices

• "discarded" means thrown away or rejected, which fits the context of removing polluted water to replace it.
• "transferred" means moved from one place to another, which does not capture the sense of getting rid of waste.
• "invalidated" means made officialy void or untrue, which is irrelevant to water.
• "distributed" means shared or spread out, which contradicts the idea of replacing polluted water.

Answer:

• (A) discarded (Correct answer)
• (B) transferred
• (C) invalidated
• (D) distributed
