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 (", ").

Paragraph- Sent 1: Are there other examples of static discharge?
Sent 2: The answer is yes.
Sent 3: Lightning is a form of static discharge.
Sent 4: It is much more dramatic than what happens to your hand.
Sent 5: You can see how it occurs in the following diagram.
Sent 6: You have probably seen lightning in a rainstorm.
Sent 7: What does lighting have to do with static electricity?
Sent 8: As it turns out, everything.
Sent 9: During a rainstorm, clouds are pushed along by the wind.
Sent 10: Clouds develop regions of different charges.
Sent 11: This happens due to the movement of air molecules, water drops, and ice particles.
Sent 12: The negative charges are mostly at the base of the clouds.
Sent 13: The positive charges are mostly at the top.
Sent 14: The charges continue to build up.
Sent 15: Suddenly, you see the large discharge.
Sent 16: This is what we see as lightning.
Sent 17: In the video below, you can watch an awesome slow-motion lightning strike.
Sent 18: Be sure to wait for the real-time lightning strike at the end of the video.

Paragraph- Sent 1:   In the second place, you should obtain specific and detailed command of general ideas.
Sent 2: Not of out-of-the-way ideas.
Sent 3: But of the great basic ideas that are the common possession of all mankind.
Sent 4: For through these basic ideas is the most natural and profitable approach to the study of synonyms.
Sent 5: Each of them is represented by a generic word.
Sent 6: So elementary are idea and word alike that a person cannot have the one in mind without having the other ready and a-quiver on his tongue.
Sent 7: Every person is master of both.
Sent 8: But it is unsafe to predicate the person's acquaintance with the shades and phases of the idea, or with the corresponding discriminations in language.
Sent 9: He may not know them at all, he may know them partially, he may know them through and through.
Sent 10: Let us suppose him ignorant of them but determined to learn.
Sent 11: His progress, both in the thought and in the language, will be from the general to the specific.
Sent 12: His acquaintance with the idea in the large he will gradually extend to an acquaintance with it in detail, and his command of the broad term for it he will little by little supplement with definite terms for its phases.
Sent 13: An illustration will make this clear. 
Question: How is knowledge formed?.

Paragraph- Sent 1: Inside, the building opened up.
Sent 2: The ceiling was high and wooden, and I could see part of a DJ’s booth down the hall.
Sent 3: It looked like we were in the back of a nightclub.
Sent 4: Then I looked down and saw what had let us in.
Sent 5: “Nepthys, my man!
Sent 6: What up?” The hunchbacked being who let us in held out a scraggly paw for him to slap.
Sent 7: “Nice, my man,” he said as they clasped hands.
Sent 8: “Who’s the freak?” “This is someone from Ivan’s family.
Sent 9: Did I ever tell you about them?” “Yeah, one time, man, but you were pretty fucked up.
Sent 10: What’s your problem, kid?” The hunchbacked man came up to my stomach.
Sent 11: His skin was brown and stretched, like some diseased sapling’s bark.
Sent 12: It pulled back around his fingertips, which bore things that might have been nails or claws.
Sent 13: When he grinned, I saw that his teeth were sharp and small, like a hunting cat’s.
Sent 14: Under matted hair, his eyes had slit pupils.
Sent 15: Nepthys quickly answered for me.
Sent 16: “Girlfriend troubles.
Sent 17: She came down here with someone after a party, and I don’t think it was one of your average pixies.” “Bummer.
Sent 18: So, what’s the cat look like?” He turned to me.
Sent 19: Nepthys nodded: “It’s okay, you can trust him.
Sent 20: That’s why we came here.” It was easier to talk than to question. 
Question: What did the hunchbacked man's teeth look like?.
