Answer 1

We can break these sentences into two sentences:

She was at his side when he was in the garden.  

She was at his side when he was chopping woods.

Explanation:

• There are two types of clauses: dependant and independent.
• A dependent clause cannot stand alone, however, an independent clause can survive alone.
• In the given sentences "She was at his side" is an independent clause and "when he was in the garden" is a dependant clause.
