Why do you need help with this question? It’s just asking you to give an example of an experience in your life that made you question your life and your approach to it.
The plot concludes in the "resolution" stage
The sentence that is an example of a faulty coordination is: The guitar is used in a lot of contemporary music, and the instrument probably originated in Spain during the 1500s. What makes this sentence's coordination faulty is that, the first part talks about guitars are used in contemporary music, but on the second clause, the topic became the history of the instrument. There is no coherence in the sentence.
-IL Means not. For example, illegal and illogical.
