What does the speaker doubt in 'The Road Not Taken'?

• A. The road's length
• B. The map's accuracy
• C. The weather
• D. Making a decision

Answer: (D)

The main idea being tested is the speaker’s doubt about choosing between two options and what that choice will mean. In the poem, the speaker stands at a fork in the road, looks down both paths, and notes that they are worn about the same. He cannot travel both and must decide which way to go. The moment of choosing—taking one road while recognizing the other might remain unchosen—highlights a hesitation about making the right decision and about the future consequences of that choice. The line about doubting whether he will ever come back reinforces that the decision has a lasting, possibly irreversible weight.

There isn’t any emphasis on the road’s length, on maps or weather, or on external details. The focus is on the internal act of deciding and the sense that this decision will shape the speaker’s life, which is why making a decision is the best answer.
