My mom is always repeating the same old joke: if your friends all jumped off a cliff, would you jump, too? of course not. but i get what she means. she's talking about peer pressure. teenagers like us live with it every day. pretty much every kid wants to be liked, to have friends, to be popular. no one wants people to think they aren't cool. while peer pressure is tough, giving in to it and getting in trouble is tougher. but teenagers are still learning to make good decisions. like this one time my friend harold wanted to take his dad's prized jeep grand cherokee for a drive. harold was 13, and he'd never driven a car before. but he figured he knew enough about operating a motor vehicle just by watching his parents drive. when his parents were out of town one weekend, harold invited me and some of our friends over to his house so he could take us for a drive. i said, "not me," because i knew it was a stupid thing to do. i told him and everybody else what i thought of the idea. (driving isn't easy. it took my big brother weeks to get the hang of it.) harold got mad and told me i was being a chicken. i said, "i'd rather be a chicken than get in an accident and have a broken leg." what is the topic of this passage?

Which the number is main idea? i need . (1) aside from its enormous population—an estimated 280 million—the lowly cockroach has some amazing characteristics. (2) in the first place, the bug is fast. (3) even the smallest roach can run up to three miles an hour. (4) what’s more, cockroaches can change course as often as twenty-five times in a second, making them the most nimble animals known. (5) roaches are tough to catch. (6) with sense organs located front and back, they can start to flee from predators within 0.054 seconds of detecting potential danger. (7) second, they are ideally adapted to living with people. (8) they eat almost anything and are comfortable anywhere as long as the temperature is above freezing. (9) most species can fit through a crevice no wider than the thickness of a quarter, so any building gives them endless places to rest and breed. (10) and they’re perfect travelers, hitching a ride in pant cuffs or grocery bags. (11) finally, the cockroach has an astonishing capacity for survival. (12) it can hold its breath for nearly forty minutes under water. (13) because its brain is spread throughout its body, the roach can survive for several weeks if its head is removed carefully enough to prevent it from bleeding to death. (14) and because roaches sample food before it enters their mouth, they have learned to avoid foul-tasting poisons. (15) this makes them hard to kill with insecticides.
