less equipment in contact with sea water, the corrosion problems are much reduced in a central cooling system. A. Because B. With C. Without D. Though

The correct answer is B. With. The sentence requires a preposition to introduce the condition of "less equipment in contact with sea water," and "With" properly establishes this relationship. "Because" would require a clause (e.g., "Because there is less equipment..."), while "Without" and "Though" create illogical meaning in this context.

Sentence with correct answer:
With less equipment in contact with sea water, the corrosion problems are much reduced in a central cooling system.

This construction uses "With + noun phrase" to establish the condition that leads to reduced corrosion, creating a clear and grammatically correct relationship between cause and effect. How might this principle apply to other marine engineering systems where corrosion is a concern?
