One day, the rich man was walking in the village and he saw another man building a stone house.
He watched as the man worked, cutting the pieces of stone and putting them one on top of another to build a beautiful house.
Question 1. He watched AS the man worked…
The word “as” in the sentence means “when”, right?
Question 2. putting them “ONE on top of ANOTHER”…
What do the words “one” and “another” mean in the sentence?
Thank you!!!
