The answer is matter and energy
I think the best answer for this question would be "D" because the Ancient Greece population was the kindest of them all so they had to show some respect to the doctors, nurses, and the workers in the hospital.
Also, "A" wouldn't be correct because the Greek gods and goddesses weren't strangers, they were respected people in there tribe.
Furthermore, "B" wouldn't be right because in the time of the Greek times, there was wars all over the empire surrounded by the wars from other empires too.
And lastly, "C" obviously can't be right because there weren't even so good bathrooms in the time, so I believe there just couldn't be any inns at their times. I mean c'mon, this was the time before Jesus was born! Lol!
The three wrong answers I chose wrong didn't even include anything about hospitality so "D" is definitely right!
Id say the answer to most of that question, is how approachable you look to the opposing person. everyone has their own preferences though you know?
The prepositional phrase for this sentence is "go until Friday." The word "go" is a preposition. Think of it as a squirrel and a log. To find a preposition, say "The squirrel (went) [insert preposition] the log." If it makes sense, it is a preposition. Then just find the phrase to go along with it!
