Fill in the blanks with the word/pair of words which best fits the meaning of each sentence. The performance of the young artist was so ____that it left an _______ impression on my mind and made me look forward to their future endeavors.
Explanation: The structure suggests a cause-and-effect relationship: a positive performance causes a strong impression and a positive feeling about the future. "Compelling" (forcefully interesting) is a strong positive adjective. "Indelible" (permanent, unforgettable) describes the impression. This combination fits the tone and logic perfectly.
