When Harry drew near the fire, he nearly singed his jacket.
Explanation:
The original sentence is compound, meaning it consists of two independent clauses, or clauses that can stand alone separately. On the other hand, a complex sentence consists of at least one dependent clause and one independent clause.
By rewriting <em>Harry drew near the fire </em>(which is an independent clause) as <em>When Harry drew near the fire </em>(which is a dependent clause that cannot stand alone), we create a complex sentence along with the independent clause that follows.
