The people's relationship with the colonists were dissent, thinking that they were dirty fools living in their own garbage. they thought they deserved to be persecuted and could not be tolerated
I'm kind of confused as to what is being asked.... but this is my best answer.
SOCIAL Prejudice, (maybe legal if we talk about the consequence to his actions)
why it cant be the others--->
racial ---- they say nothing about race here.
(MAYBE) legal----- from the passage, we can say that the guy is richhhhh, and he might be able to wave off the consequences of his murder. but then again you only analyze this passage so, probably not
environmental---- they don't mention the environment....
THE REASON WHY IT SHOULD BE SOCIAL- their social standings in this situation
-diamond ring (if thats what they mean by diamond ring finger, it could mean something else as well) only the rich can afford, a cane too
- hotel society gathering... (rich)
-poor Hattie Carroll could be literal as well.
It would be Admissions Ward
Usually, when you talk to your friends, you don't follow every grammar rule in the book. This is why spoken English is far more informal and flexible, giving room to slang. In the same way, with the exception of the first example, all the other sentences follow conventional Standard English grammatical rules. Only the first sentence shows a more conversational syntax (word order) being used. Therefore, the best answer is A.
On that note, we could infer that the first example sounds like how British speak, as they are known for their frequent use of tag questions.
