Show answer & explanation
Correct answer: B
Solution
The segment containing the error is the verb phrase "were required to"; the verb should be singular.
Explanation:
The subject "Five gallons of oil" names a quantity or unit of measurement. When a measurement, amount, or period is regarded as a single unit, it takes a singular verb.
Therefore, use the singular verb "was" instead of "were."
Correct sentence: Five gallons of oil was required to get the refinery running.
Key rule: When a quantity is treated as a single unit, use a singular verb.
Application: "Five gallons of oil" = single quantity → use "was required to."
