I don’t know what you mean by this can you reword it?
He is poor and cant afford a great gift
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.
Simple sentence it has a subject and a verb train being the subject and traveling being the verb fast being the adjective.
