There wasn't too much of a reaction in the crowd, as to them he was just another dead African-American person. Read chapter 25 over to possibly understand better.
The sentence that uses parallel structures is B) My three favorite activities are writing, reading, and going to the library.
A parallel structure means that the same form of a verb is used in a sentence, and as you can see, here only gerunds are used - writing, reading, going - they all have -ing in the end.
The other sentences don't have a parallel structure because they don't use the same forms.
Robert Hooke has had a great impact in the world of science. His discoveries and even inventions are still used to this day. He's someone that greatly inspires me because of his determination. Something that caught my attention and intrigued me is his studies of the structure of snowflakes and his cork studies. He was also the one that first used the word cell while he studied and looked into corks. If I could meet Robert Hooke, I would say thank you for contributing to science and ask if he ever thought of evolution.
