<span>During the famous battle of Iwo Jima, six Navajo code talkers operated continuously, transmitting each message without a single mistake.
This piece shows that the Code Talkers not only had to work fast-continuously transmitting the messages, but that they also were extremely precise-since it mentions they did not make a single mistake. </span>
I would say the last choice, or answer four is the best fit topic sentence.
The sentence summarizes and explains the paragraph accurately. The first two choices make sense but don't best fit this paragraph in particular. Choice 3 is good too but the paragraph goes more into detail about the actual park and not his parent's motives.
1. since she likes to help people
2. branches in the street
3. no one else wanted to ask
4. how democratic he is
5. when she wants to have a snack
7. because they never see each other
8. we didn't get any
9. until i lost my job
10. while the men work hard
It is going to be a run-on-sentence I think
