Personally I would start with a quick warm up. Next, try paced run maxing out at 6:25's for a minute, then dropping back to 7:00 pace for 5 minutes before repeating.
Answer:
The sentence that is correctly punctuated is the following one: "Let's get going," Ginnie shouted, "it's getting dark!"
Explanation:
The sentence above is a direct quotation. Quotation marks are for when you want to include someone else's words in your own writing. What is more, direct quotations contain a quote in which you report the exact words used.
In this case, the quote has been split. When you split a quote to introduce a parenthetical, you shouldn't capitalize the second part of the quote example: (it's getting dark!"). Also, the exclamation mark goes inside the quote because it applies to the quoted material, not to the whole sentence. For these reasons, the sentence chosen is the one that is correctly punctuated.
The correct answer among all the other choices is "The tall skyscrapers in New York City maximize the space of a small area." This sentence can be revised to eliminate redundancies. Thank you for posting your question. I hope this answer helped you. Let me know if you need more help.
