I chose answer B because the paragraph aims at the fact that people must have alternative or, in this case, altruistic motives to achieve selfish reasons. I think altruistic motives in C is assumption bait, but that is what I came up with because I did not know the definition of altruistic very well and, in the answer B, I thought the word property could have a definition that meant a "building or buildings and the land belonging to it or them"(Oxford Languages) not a property like "an attribute, quality, or characteristic of something"(Oxford Languages).

A Christ-centered study group, that sounds like a great idea!!

I think your explanation of an argument, premise, and conclusion is great! Thank you!
