Question

Choose the complex sentence.

• When Abby raises her hand, the
teacher calls on her.

•The dog flung itself into the swimming pool.

•She saw a rabbit that needed a home, and she wanted to adopt
it.

•The weather was perfect, so they went fishing.

Answer 1

B (?)•The dog flung itself into the swimming pool.

Step-by-step explanation:

definition of a complex sentence:

A complex sentence combines a dependent clause with an independent clause. When the dependent clause is placed before the independent clause, the two clauses are divided by a comma; otherwise, no punctuation is necessary.

"The dog flung itself." is an independent clause because it expresses a complete thought, this alone could be considered a sentence.

"into the swimming pool." is a dependent clause, it doesn't express a complete thought and on its own is very unclear;

however, by putting the two together you -- by definition-- get a complex sentence, no comma is needed because the independent clause is used first.
