Answer:
It doesn´t, taken in account the word <em>long.</em>
Explanation:
It seems to me that the question should be formulated like this:
<em>How does this document etc.</em>
Because the either supporting or expanding of the textbook version can´t be measured in time; you either support it or you expand on it.
Bilbo's indecision about whether he should go on the adventure: his determination to give it a go. The last one. I think I'm late. :/
No, you only have to write 1 just reflect on what you learned or whatever the topic is
Hello!
The most cohesive concluding sentence is that of option C - "If community members do not get involved with watching their own neighborhoods, they might be vulnerable to major and minor crimes."
This sentence seems to wrap up an essay far better than any of the others, and can even serve as a thesis statement.
Options B and D seem to be good supporting points/ideas for body paragraphs, while option A could serve as a good hook for the introductory paragraph. Option C serves best as a concluding statement.
Hope this helps!
