C. Instance, because you are using a dash to separate the list from the rest of the sentence
So there would be someone to blame for her mother's leaving
The correct preposition that you should add to make the sentence correct is TO. The answer is then "To facilitate a quick getaway, the cunning thief parked the car perpendicular to the building". Perpendicular things always have the preposition TO next to them.
1) When did she come home yesterday
2)Do you go to school on Saturday
3)Perhaps tomorrow it won't rain
4)Did they read that book
5)Has he got a new car
6)Will you buy her a present
The correct answer is: It is more easily understood by the reader.
When Thomas Jefferson gave the speech on The Declaration of Independence he had appealed to the people by giving them something that's clearly understandable and something that they can agree or disagree to on some degree.
Thomas Paine on the other hand was not specific on the speech and gave jargons and stories that only he and the government can understand and not of the people.
Jefferson's appeal is more effective because he understood the plight and the sufferings of his people, and that freedom is something that all humans can achieve in any society to which they belong to.
