Two male singers, Peer and Shaer; two female singers Rina and Vina; two male dancers Tapu and Wahed; and two female dancers Queen and Usha, are the eight entertainers who are to perform at the Bengal Theater on a certain night. Each entertainer is to perform alone and only once that night. The entertainer may perform in any order that conforms to the following restrictions: The performances by singers and the performances by the dancers must alternate throughout the evening. The first performance that evening must be by a female entertainer, and the second performance by a male entertainer. The final performance must be by a male singer. Which of the following must perform eighth?
Explanation: The final performance must be by a male singer. Male singers are Peer and Shaer. The question in the prompt is missing for this question, but based on the answer in the source (Shaer) and the restriction (final performance must be a male singer), the question is likely about the eighth performer, which is the final performance.
