Analyze the original sentences

Sentence 2: "He uses these techniques at the same time."
Sentence 3: "His use of the techniques emphasizes important ideas."
Both sentences are simple sentences, making the writing repetitive and lacking variety.

Evaluate the options

• Option 1: "King uses two techniques at the same time. The techniques emphasize important ideas." (Keeps them as two separate simple sentences; does not combine them).
• Option 2: "King uses the techniques at the same time, an emphasis of ideas." (Grammatically awkward and changes the meaning/clarity of the original sentences).
• Option 3: "King uses both techniques at the same time so that he can emphasize important ideas." (Successfully combines the two sentences into a complex sentence using the subordinating conjunction "so that", establishing a clear logical relationship and adding sentence variety).
• Option 4: "King emphasizes important ideas. He uses the techniques at the same time." (Keeps them as two separate simple sentences; does not combine them).

Identify the correct choice

Option 3 is the only revision that successfully combines the sentences into a single, grammatically correct sentence that improves sentence variety and maintains the original meaning.
