Tests an AI's ability to solve a simple but potentially confusing logic puzzle
I need to think through this step-by-step.
Given information:
Let me work out how many sisters are in the family total.
If each of Sally's 3 brothers has 2 sisters, and all the brothers are in the same family, then there must be 2 sisters total in the family.
Since Sally is one of those sisters, and there are 2 sisters total, Sally must have 1 sister.
Therefore, Sally has 1 sister.
Let's break down the problem:
Let's analyze:
Sally's siblings:
The brothers' sisters:
Who are the possible sisters for each brother?
If Sally is the only girl, then each brother would only have 1 sister (Sally). But the problem says each brother has 2 sisters.
Therefore, there must be another sister besides Sally.
Let's check: Suppose Sally has 1 sister (besides herself). So the siblings are:
Children in the family:
Now, for each brother:
So, Sally has 1 sister.
Final answer:
[ oxed{1} ]
Sally has 1 sister.
Tests an AI's understanding of number representation
No, 9.11 is not greater than 9.9.
To compare these decimal numbers:
Since both numbers have the same whole number part (9), we compare the decimal parts:
Therefore, 9.9 is greater than 9.11.
No, 9.11 is not greater than 9.9.
9.11 is less than 9.9.
This might seem counterintuitive, but when comparing decimal numbers:
So, compare 9.11 and 9.90:
Therefore, 9.11 is less than 9.9.

So I'm 30 now, which means I'm officially an adult. Apparently. Though I still feel like I'm just a confused teenager wearing a slightly more expensive t-shirt.
You know what nobody tells you about being an adult? How much time you spend pretending to understand what other adults are talking about. I was at a dinner party last week – because that's what we do now, we have "dinner parties" instead of just "eating pizza on the couch" – and someone started talking about mortgage rates.
I just nodded along like, "Oh yes, rates. Very mortgage-y." Meanwhile, I'm thinking a mortgage is something you get at a fancy French restaurant.
mimics sophisticated nodding
"Mmm, yes, I'll have the mortgage, medium rare."
And don't get me started on small talk with neighbors. I live in an apartment building, and there's this unspoken rule that you have to acknowledge each other in the hallway. But what do you say?
"Hey, nice... existing near me."
"Thanks, you too. Love what you've done with your... door."
The worst is when you're both waiting for the elevator in complete silence. It's like a hostage situation, but with more awkward eye contact. You're both just standing there, praying the elevator comes before one of you has to comment on the weather.
stares ahead uncomfortably
"So... it's very... outside today."
I tried being one of those people who meal preps. You know these people? They spend their entire Sunday cooking seventeen identical containers of sad-looking chicken and broccoli. I bought all the containers, felt very organized, very adult-like.
Week one: Perfect little meals, properly labeled. I felt like a productivity guru.
Week two: I'm eating cereal for dinner and using the containers to store my collection of takeout sauce packets.
holds up imaginary container
"Ah yes, vintage soy sauce, 2023. A good week for Chinese delivery."
Speaking of food, grocery shopping as an adult is weird. When you're a kid, the grocery store is magical. Everything looks amazing. You want the cookies, the candy, the sugar cereal with the cartoon mascot.
Now I walk through the store like a tired parent, even though I don't have kids. I'm just disappointed in all my options.
walks slowly, shaking head
"This yogurt has too much sugar. These crackers have no fiber. Why is everything either terrible for you or tastes like cardboard had a baby with sadness?"
And I've started doing this thing where I read nutrition labels like I understand them. I don't. I just nod thoughtfully and put things back like I'm some kind of wellness expert.
"Hmm, seventeen grams of... things. That seems like too many things."
The real kicker is when you find yourself getting excited about household appliances. Last month, I spent twenty minutes explaining to my friend why I love my new vacuum cleaner. TWENTY MINUTES. About a vacuum.
"It has three different settings! And look at this attachment! This little brush thing goes in corners!"
My friend just stared at me like I'd been replaced by a suburban mom from 1987.
But you know what? I've decided to embrace it. Yes, I get excited about good storage solutions. Yes, I have opinions about thread count. Yes, I've used the phrase "back in my day" unironically, and I'm only thirty.
shrugs confidently
Because being an adult isn't about having it all figured out. It's about confidently pretending you know what you're doing while secretly googling "how to fold a fitted sheet" for the hundredth time.
And if that's not the American dream, I don't know what is.
pause
Also, if anyone actually knows how to fold a fitted sheet, please find me after the show. I'll pay you.

Thank you, you've been a wonderful audience! Don't forget to tip your servers and call your parents – they're worried about you!

Absolutely! Here's a 3-minute stand-up routine with no puns—just observational and relatable humor:
You ever try to get healthy, but your body's like, "Whoa, whoa... calm down, superhero." I joined a gym—first time walking in, the treadmill looked at me like, "We both know you're here for the wifi." They hand me a to wel and I'm like, "Oh, I'm not gonna work up enough sweat to justify this, but thanks for believing in me." I try eating salads. I don't understand people who say salads fill them up. I finish a salad and immediately want to reward myself—with a pizza. The salad's just the job interview, the pizza's what brings me real joy . That's why my salad always comes with a side of fries. My body's like, "You remember vegetables, right? In troduce them to their friend, carbohydrates."
Ordering food is hard. Restaurants make everything so customizable now. "Do you want that grilled or fried? Pick your bun, pick your sauce, choose your mood for the day." By the time I'm done I feel like I've taken t he SATs. And that's before they ask about up-sizing. "Would you like to upsize for just a dollar?" I always say no—because I'll pay twice that much in guilt.
Dating apps are even worse. Your thumbs do more cardio than your legs. Swiping is the new stairmaster. Profi les always say, "Love to travel!" I match with you, you mean going to Target in a different zip code. Why do we act like flying to Portugal is our hobby? Meanwhile, my idea of exploration is getting up to find the re mote.
I tried meditating because they say it's good for stress. My head is full of thoughts. The app says, "Let yo ur thoughts float by like clouds..." Suddenly all my clouds are bills. Student loans, dental bills—I'm basical ly in a storm.
And then there's technology. My smart watch knows I've been sitting for too long. Every hour, it vibrates, " Time to move!" It's like a parole officer living on my wrist. I miss the days when only my conscience judged me for lying on the couch. Now I have a device, "You've walked 32 steps today... are you...are you okay?"
But in the end, I'm trying! One salad at a time. One step. One dating profile. And sometimes, one slice of p izza. Because let's be honest—no one ever had a life-changing moment during a salad.
Thank you, everybody!
