How long did Grandpa work on Roberta to get her restored?

• A. Eighteen months
• B. Six months
• C. Two years
• D. Nine months

Answer: (A)

Recognizing how long a restoration project takes helps you see the level of care involved. In this story, Grandpa spent eighteen months on Roberta, a long, steady effort that shows meticulous work and dedication. That span covers the time needed to plan, source parts, and perform careful repairs without rushing. Shorter periods wouldn’t quite fit the gradual progress described, while a much longer time like two years would imply an undertaking beyond what’s depicted. So eighteen months best matches the narrative and explains why this choice is correct.
