The sentence which is the most objective is <span>A. My mother taught Italian lessons at the community center.
</span>It is a fact, therefore it is objective. The other sentences are somebody's opinions - stupid sisters, crazy Greek family, a real pain - these words show that it is someone's opinion, which is subjective, not objective.
No word choice shown but for example "go, search, roam and travel" are used to show the wide scope of the investigation of barbaric practices in the world and then "revolting barbarity and shameless hypocrisy" are two strong expletives that show the degree of horror of the practices of the US at least according to this author.
