Answer:
Step-by-step explanation:
The statement "To make an idea in a sentence more important, subordinate it" is not true. Subordination in sentence structure is used to make a dependent clause less important than the main clause. In other words, subordination is used to show that one idea is secondary or supportive to another idea in a sentence. To make an idea more important, it is typically emphasized or given prominence within the sentence, rather than being subordinated.
