Final answer:
Jerry 'hesitated' at the idea of singing, implying a pause due to uncertainty, but ultimately followed through with his promise to participate.
Step-by-step explanation:
The word you are looking for to describe Jerry's reaction to singing in the amateur show is 'hesitated.' When someone hesitates, they temporarily pause or delay in decision or action, often because of uncertainty or fear. The word 'resisted' would imply a stronger opposition to the idea, while 'faltered' suggests a loss of momentum or strength, and 'embraced' indicates acceptance with open arms, which is the opposite of hesitation.
In this context, Jerry shows some reluctance at first but decides to move forward with the singing performance due to the commitment he had made, showcasing his hesitation but not a complete resistance, falter, or enthusiasm.
