The punctuation mark that should be placed after the close quotation mark is a period. A period is used at the end of the sentence to indicate where the sentence fully stops. In the example given above, it is made up of two complete sentences with different thoughts each. Therefore, it should be written like this: I understand that "time is of the essence". I just need to find my keys so we can leave!
Answer:
Born into slavery in Maryland, Harriet Tubman escaped to freedom in the North in 1849 to become the most famous "conductor" on the Underground Railroad. Tubman risked her life to lead hundreds of family members and other slaves from the plantation system to freedom on this elaborate secret network of safe houses.
I'd say that the statement from FDR's speeches that uses parallel structure is C. American ships have been sunk; American airplanes have been destroyed.
Both of these independent clauses use the passive form of the verb - in the first clause, the passive form of the verb <em>to sink </em>is used, and in the second, of the verb <em>to destroy.
</em>A parallel structure means that throughout a sentence, the same form of words is used, and given that here both sentences have passive forms, I'd say C is the correct answer.<em>
