Great good luck sometimes touches a person at least once. It touched me. A book he wrote became a best-seller in 16 countries. I bought a house on the beach. My dream had come true.
These sentences are taken from "Dreams Do Come True" by Jim Bishop.
Someone asked me a question concerning it. The question is as "Why did the boy become rich?" If I answer this question by using "by verb-ing" in the following way, is it acceptable or grammatical ?
Ans: The boy became rich by writing a book which became a best-seller in 16 countries.
