Driving in Lagos is a difficult task.

Step 1: Analyze the question You are asked to find the option that best restates the meaning of "Driving in Lagos is a difficult task." The meaning must stay the same, with no change in the level of difficulty and no change in the facts.

Step 2: Explain the concept This is a sentence-meaning (paraphrase) question. The correct option must:

• keep the same meaning (driving in Lagos is hard), and
• stay grammatically correct and idiomatic.

Step 3: Evaluate each option

• A. "It is an easy task to drive in Lagos" says the opposite. Wrong.
• B. "It is a difficult task driving Lagos" has the same meaning, but it is grammatically faulty. The preposition in is missing, and you drive in a city, not "drive Lagos." Wrong.
• C. "It is a herculean task driving in Lagos" keeps the meaning. "Herculean" means extremely difficult, so it is a fitting synonym for "difficult," and the sentence is grammatically correct, with in kept. This fits.
• D. "It is not a difficult task to drive in Lagos" negates the original. Wrong.

Step 4: Answer Option C is the best choice. It is the only option that is both grammatically correct and consistent with the original meaning. "Herculean" is a stronger word than "difficult," but it still conveys the same idea, and it is the closest match among the four.

Step 5: Exam tip In paraphrase questions, first eliminate options that are opposites or negations (A and D here). Then check the remaining options for grammar slips, such as the missing preposition in B. "Herculean" comes from the Greek hero Hercules, famous for his impossible tasks, so remember it as "needing the strength of Hercules."
