1.5.1 study: word meaning, part 2
which word could best replace combat without changing the overall meaning of this passage?
drinking water helps combat disease and leads to good health. fluid losses occur constantly, and these losses must be replaced daily. drinking at least eight glasses of water a day can help combat dehydration. water is an important part of a healthy lifestyle.
a. fight
b. support
c. encourage

Explanation:

To determine the best replacement for "combat", we analyze the context. In the passage, "combat" is used to mean acting against disease and dehydration. "Fight" has a similar meaning of opposing or struggling against something, which fits. "Support" would imply aiding the disease/dehydration (opposite of intended), and "encourage" doesn't fit the context of acting against a negative condition.

Answer:

A. fight
