Question

passage 1
identifying complete, correct sentences and sentences with parallel structure
read each answer choice. three of the choices are sentence fragments or run - on sentences, or they have problems with parallel structure. one is a complete, correct sentence. identify the complete sentence.
\did you know,\ our teacher said, \that neurons
○ transmit nerve impulses, which are basically surges of electricity?\
○ collecting nuts and running all over our yard.
○ if you are joining us at the concert this evening,
○ the burgess shale in canada, one of the most impressive fossil beds on earth.

Explanation:

The correct option is a complete sentence with a main clause ("our teacher said") and a nested clause ("that neurons...electricity"), forming a grammatically complete structure. The other options are fragments: "Collecting nuts..." lacks a predicate; "If you are joining..." is a dependent clause without an independent clause; "The Burgess shale..." lacks a verb to complete the sentence.

Answer:

"Did you know," our teacher said, "that neurons transmit nerve impulses, which are basically surges of electricity?"
