I obviously know few details about Newton. Did well on all the others (Einstein, Feynman, LHC) but only 4/12 on this and most were guesses, mostly wrong. Of course, there is a giveaway answer in there ... (but that one I knew anyway).
There is a bit of a problem with Question 8. It reads ---
8. Although born an Angelican Christian, what sect did he start following in his 30s?
The three "wrong answers," (Methodist, Lutheran, and Calvinist) are all organized, recognized branches of Christianity. There is no organized religion called Arianism.
The first ecumenical council of the Christian Church was called by Constantine in 325 AD to settle the issue of the relation between Jesus Christ and God the Father. One churchman, Arius, took the position that Christ was the creation of the Father and thus had a beginning. Another churchman, Athanasius, took the position that Christ and the Father were essentially one, both existing together from before the beginning of time. The final product of the council was the doctrine of the Trinity, the idea that God exists in three Persons, the Father, the Son, and the Holy Ghost, all equal and all from co-existant before eternity. This was expressed in the Nicene Creed and also in the Athanasian Creed.
The council condemned the position of Arias, now known as the Arian Heresy, which denies the doctrine of the Trinity. Newton, after much study, was unable to accept the doctrine of the Trinity, so by default, he accepted the Arian Heresy. He did not walk down the street and join an Arian Church, there was no such and never has been. Through the ages there have been individual Arians, but never any organized branch of the church called Arianism.
