How does the structure of mike kubic's article support the central idea of his claim in the salem witch trials and other witch hunts

Kubic's article has three parts. In the first part, he gives the full account of the witch trials which took place in 1692. The author shows how convicted people were actually not guilty of the accusations. In the second part, he writes that how exactly 100 years later the mass execution of the enemies of the revolution in France, so called "Reign of Terror" followed the similar patterns. The paragraph about the mass execution of Jews is also mentioned in the article. In the last part named "Public Scares in the USA", Kubic somehow summarizes the culmination of these historic demagoguery giving the examples of resettlement of Japanese Americans, First and the Second Red Scares in 20th century America ans concludes that prevalence of prejudice was still on the agenda even after two and half century later.  

i think its d, but grammarly says none

explanation:

the boy's acceleration toward the girl is 2.08 m/s^2.

explanation:

according the newton's third law, the force causing the girl accelerate towards the boy will be me with equal counter-force causing the boy to accelerate towards the girl. these forces will be of equal magnitude and allows us to determine the boy's acceleration:

the boy's acceleration toward the girl is 2.08 m/s^2.
