Final answer:
Complex sentences are identified by the presence of an independent clause and at least one dependent clause. Sentences 2 and 3 are complex; sentence 2 has a dependent clause introduced by 'since', and sentence 3 starts with the dependent clause 'When Audrey gets home'.
Step-by-step explanation:
In identifying complex sentences from the provided options, we look for sentences that contain an independent clause and at least one dependent clause, which starts with a subordinator such as 'when', 'though', 'because', 'if', etc.
- Carlos will get the paper; Meg will get the markers. (Not a complex sentence; this is a compound sentence joined by a semicolon.)
- Sasha has been learning karate since she was eight years old. (This is a complex sentence because it has a dependent clause introduced by 'since'.)
- When Audrey gets home, she will make dinner for Miranda. (This is a complex sentence because it has a dependent clause starting with 'when'.)
- It is getting late, but there is no school tomorrow. (Not a complex sentence; this is a compound sentence joined by the coordinating conjunction 'but'.)
- wants to go to the mall even though he has no money to spend. (This would be a complex sentence with the dependent clause starting with 'even though', but it is missing a complete independent clause.)
