You are given a paragraph, with numbered sentences, and a question. Write the numbers of the sentences needed to answer the given question. Separate multiple sentence numbers with a comma (", "). E.g. "1, 2" would be the correct response if Sent 1 and Sent 2 are needed to answer the given question (do not include sentences that contain no information that is necessary to answer the question). Sort the sentence numbers in an increasing order (i.e., '1, 2', instead of '2, 1'). Your answer should not contain anything than the sentence numbers separated by a comma (e.g. '1, 2, 3, 4'). The given question requires more than one sentence to answer. So, your answer must contain at least one comma (", ").

[Q]: Paragraph- Sent 1: The bar was manned by an expensive humanoid robot.
Sent 2: It turned toward Sarah's wave and acknowledged her with a nod, moments later setting a fluted glass of sparkling liquid in front of her.
Sent 3: I marveled at the robot's smoothness and coordination.
Sent 4: Clearly, it was a high-end model.
Sent 5: Sarah transferred the glass to my free hand and pulled me away from the bar for more introductions, with Alexis trailing after us.
Sent 6: I spent the evening listening, mostly.
Sent 7: Listening and stuffing my face with all the bits of fine food provided.
