Final answer:
A compound-complex sentence using 'until' and 'and' is provided, encompassing two main clauses and two subordinate clauses to illustrate a sentence with multiple ideas. The sentence is "She didn't realize how late it had gotten until the movie ended, and she had to rush to catch the bus, and her brother, who usually waited for her outside the theater, had already gone home."
Step-by-step explanation:
An example of a compound-complex sentence using the conjunctions 'until' and 'and' could be: "She didn't realize how late it had gotten until the movie ended, and she had to rush to catch the bus, and her brother, who usually waited for her outside the theater, had already gone home."
In this sentence, 'She didn't realize how late it had gotten until the movie ended' and 'she had to rush to catch the bus' are the two main clauses, indicating two separate, complete ideas. The phrase 'until the movie ended' serves as a subordinate clause to the first main clause, and 'who usually waited for her outside the theater' acts as a subordinate clause to the second main clause, adding additional information to the sentence structure.
