The sentence that can be removed <u>without affecting the explanation</u> is "<em>In the 1800s, the United States was still a very young nation, trying to solidify its identity</em>."
The reason this sentence can be removed is that it does not offer any necessary information to the explanation. The passage is about how technology leads to bigger cities. This information is conveyed just as efficiently without the need for the first sentence. 
Rather than serving to offer information, the first sentence in the passage serves as a sort of <u>introduction</u> to the text. The very next sentence can just as easily serve as an intro to the passage while providing context for the development of early technology that led to the industrial revolution. 
For these reasons, the sentence "<em>In the 1800s, the United States was still a very young nation, trying to solidify its identity</em>." can easily be removed from the passage <u>without affecting</u> the explanation.

The main difference is that all non-fiction books have a table of contents, but not all fiction books do.

A table of content means a page or section at the front of your book that lists the chapters of the book and their corresponding page numbers.
The difference between a table of contents in a fiction book and in a nonfiction book is that all non-fiction books have a table of contents, but not all fiction books do.

The answer you are looking for I believe to be <span><span>
<u>4) A type of monologue in which a character speaks to himself and expresses his sincere feelings and thoughts.</u> 
</span></span>The actual definition of <em>soliloquy</em> is "an act of speaking one's thoughts aloud when by oneself or regardless of any hearers, especially by a character in a play"
Though choice two is a great possibility the keyword you are looking for is "speaking to himself" 
I hope this is right and helps!!
