Her success and what she is best known for are the main topics of the paragraph. So, Answer A would be your best bet. It covers all of those points.
The two senteces that most clearly describe historical elements are:
"Then, amid a murmur of laughter and jeers from the Roman benches immediately before him, he began to sing."
"It was all simple and childlike, but it went to the hearts of the Olympians, for it spoke of the land which they knew and loved."
<span>"I thought I would be bored by the Shakespeare play, but I was enthralled the whole time"
this is the correct use of the word enthralled as enthralled means to excite and captive the attention of someone or thing, and as you can see in the sentence that he was originally expecting to hate the play, but he uses the word "but" which negates the previous statement and presumably anything followed by the but would be along the lines of him actually liking the play</span>
