Correct Answer: lively

Solution : The correct choice is the fourth option.

Explanation: "Dismal" means gloomy or depressing, while "lively" means energetic and full of life. In the context of a musical performance, "lively" indicates a positive and enthusiastic presentation, which contrasts with a dismal one.

The meanings of the other options are as follows:

• Smart : Intelligence that often brings clarity but sometimes invites complexity.
• Melancholy : A deep, pensive sadness that colours perceptions and emotions.
• Exhausting : Draining of energy, physically or emotionally, due to prolonged effort or stress.

The correct sentence is: "The musician gave a lively performance of a few old melodies at last night's concert."
