Answer: In the passage, the characteristic of sentence structure that is most evident is complex sentence structure.
Explanation: The passage provided includes many complex sentences. A complex sentence is a sentence made up of an independent clause and one or more dependent clauses. While an independent clause can stand alone as a sentence, a dependent clause cannot stand by itself. Moreover, there are three types of dependent clauses: noun clauses, adverb clauses and adjective clauses. In that way, in the passage provided, there are independent clauses, such as "we take the bus", and dependent clauses, such as "which is usually an express bus" (adjective clause), "because the bus is almost always late" (adverb clause) and "that we will have to wait a long while for it" (noun clause).
