Final answer:
To rewrite the compound sentence 'Harry drew near the fire, and he nearly singed his jacket' as a complex sentence, we can use a subordinating conjunction. A revised sentence could be 'Harry drew near the fire, which almost singed his jacket.' This turns the second main clause into a subordinate clause, establishing a dependent relationship.
Step-by-step explanation:
The question asks to rewrite a compound sentence into a complex sentence by turning one of the clauses into a subordinate clause. The original sentence is: 'Harry drew near the fire, and he nearly singed his jacket.' To convert this into a complex sentence, we introduce a subordinating connector to the second clause, making it dependent on the main clause. A possible revised version could be: 'Harry drew near the fire, which almost singed his jacket.' Here, 'which' serves as the subordinating conjunction that connects the independent clause 'Harry drew near the fire' with the dependent clause 'which almost singed his jacket.'
