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: "I don't know it was going to be just us tonight.
Sent 2: I'm not sure I'm up for a night out." I was feeling calm and private that night.
Sent 3: It seemed like tonight's darkness was small and personal, cupped hands offering a place for two, not the burning, open darkness of a rave.
Sent 4: "Baby, let's go.
Sent 5: It's been over a week, and I want to dance.
Sent 6: Let's go together, you know you'll have fun once you get into it." She bit the inside of her bottom lip, looking at me like I was breaking her poor, sweet heart.
Sent 7: I'm a sucker for that, and she knows it.
Sent 8: "Okay, Rachel.
Sent 9: Let's go, you're probably right." She grinned and gave me a kiss across the table, her lips soft and firm and sticking just enough that she gave the feeling you were really kissing, not just pressing your face into someone else's.
Sent 10: "Let's not get fucked up tonight, though, okay, Rache?
Sent 11: We don't " "Sure, babe.
Sent 12: Come on, I don't have to get fucked up every time we go out just to enjoy myself.
Sent 13: Let's not waste any more time." She stood up and I followed her out to the street.
Sent 14: It was dark enough that I could actually see a few stars through the screen of city light.
Sent 15: Without hearing the car horns, I could almost taste the air of late March through the street fumes.
Sent 16: If it was March, that meant that we'd been together almost a year and a half.
Sent 17: It was last February, after the winter break, that we moved in together.
Sent 18: Now spring was back, under the concrete, and I could smell it even here.
Sent 19: "Isn't it an amazing night, Rache?
Sent 20: Even the city feels alive when spring comes." "Taxi!" She waved down a car and pulled me in.
Question: Who wants to go out dancing?.
[A]: 5, 8.

Sent 12: The correct answer is "He is alive and well and rules the world!", causing the mermaid to vanish and the sea to calm.
Sent 13: Any other answer would cause the mermaid to turn into a raging Gorgon who would drag the ship to the bottom of the sea, all hands aboard.

[A]: 5, 7, 8, 12.
