Do you know who Nancy Scott is
I am not sure what you are asking here. If you are asking what parallel structure looks like, you would have to keep the verb tenses the same. For example, Sam likes to ride bikes, hike trails, and bake bread. What is does NOT look like: Sam likes to ride bikes, go hiking on trails, and baked bread with her grandmother. The structure words would be based of the passage you were given, which isn't supplied here. If you were asked to write a paragraph using a parallel structure, follow the example given here.
He reacted because of the gift that he had gotten her. He didnt want her to cut it off.
Participle is a verbal form that is used as if it were an adjective or adverb.
So, if the verb is, for example, "to bark" the participle would be"barking" as in "this barking dog"
and the correct answer is b. barking!
I can't write the whole summary for you, but writing a summary is quite easy. Just take the main point of each chapter (in your case). Write the main point and what it caused. Kinda like cause and effect. Do this for each chapter. :) If you need anymore help, please feel free to ask! Hope this helps and have a Happy New Year!
