I remember in primary school we used to have something called "pop-com" for English and Chinese, which is a comprehension paper, but the passages used are lyrics from pop songs. They'll play the song, let you do the questions, then play the song again.

I heard this song from campus superstar, and I thought, hey, why not have it for Math as well?

"Given that 十个男人七个傻，八个呆，九个坏，还有一个人人爱, how many combinations of men are possible in a given group 10 men? Assume that all the above traits are independent of each other."

Recently I've tried Googling the term "Quine-Dubhe problem" and found that there is no such thing! It's called "Duhem-Quine problem". Gosh, I've used this term for at least 3 KI essays, and Mrs Leong hasn't spotted it yet. I think this can potentially be exploited, considering the fact that Mrs Leong is a very busy person.

The mentos advertisement doesn't make sense.

It goes like this, this guy is late for lecture. He finds that the teacher is teaching, but the teacher hasn't noticed him yet. So he pops a mentos and walks backwards into an empty seat. When the teacher spots him, he leans forward to look like he was walking out. The teacher snarls, "Where are you going? Sit down!" Then he sits down, makes faces at the girl sitting next to him and pops another mentos.

It would only make sense of the teacher is known for chasing out students who come late for lessons. It's weird to chase out people who come late for lessons but ask the students who want to sneak out to sit down. In the former case, at least the student is willing to attend the lesson. Sneaking out during the lesson is plainly disrespectful for the teacher.

So would you really rather be spotted sneaking out of lecture than to being late for lecture? Firstly, walking backwards is way slower than walking forward, so he might have a chance of being able to sneak into the class before he gets spotted. Secondly, why is he even trying to sneak in from the front of the lecture hall? He wouldn't even need to sneak if he entered from the back. Thirdly, walking backwards in front of the lecture hall would make you look like a complete jackass if things don't turn out the way you want. Fourthly, try walking into the lecture theatre backwards from the front door, and also keeping the people on the seats quiet.

For a while I also thought that the Darlie advertisement doesn't make sense, then my sister explained it to me.

Basically, it shows a few scenes. The following was my interpretation.

'One of the scenes shows a lady in the lift with another guy. She shows him her teeth and breath. He is delighted.

In the next scene the guy drops his files. The lady picks it up for him. The guy shows her his teeth and breath. She is delighted.

The last scene shows a waterpolo player shooting into the goal, and scores. The scorer shows everyone his teeth.'

The following is my sister's interpretation.

'One of the scenes shows a lady entering a lift, and she meets a guy she knows, so she says "Hi!" The guy smiles back in response.

In the next scene, the guy drops his files, and the lady picks it up for him. The guy says "Thanks!" and the lady smiles back in response.

The last scene shows a waterpolo player shooting into the goal, and scores. The scorer jumps and shouts "Yay!" in delight.'
