<u>-------------------------------</u>
Dear <u>Miss Callas</u>,
Last night, I was at <u>the Verona Arena</u> to see your beautiful <u>voice</u> with <u>a couple of my companions</u>. Your <u>voice</u> was <u>beautiful</u> and simply <u>moved me to tears</u>. The ability to perform a <u>wide variety of different roles was astounding and the dramatic strength of your low vocal range as much as the high and bright notes of your high range</u> was something I thought was <u>almost impossible</u>. I admire your <u>unique skills</u> when you <u>sang "Con Onor Muore"</u>, which I believe <u>means "With honor dies" in Italian</u>.
Sincerely,
<u>Appleπ101</u>

Hope this helps!

"Mr. Collins is surprised by the exclusive invitation."
- This is evident when he said, "I confess that I should not have been at all surprised by her ladyship's asking us on Sunday to drink tea and spend the evening at Rosings."
- This shows that he was surprised by the invitation, as he was not expecting it.
- The title of the book is Pride and Prejudice.
- Jane Austen wrote the book.
Hence, in this case, the correct answer is option C. "Mr. Collins is surprised by the exclusive invitation."
