I had never heard of "fracking" but it was easy enough to figure out from the options given. I think I could have gotten the other 12 when I was 12.
I couldn't do a test for gender because I'm at the Public Library, so I had to go on memory.

I'm sure I'd have gotten all of them when I was twelve too.
I hope you're forgetting things naturally and not deliberately unlearning them.
Faith writes:
Maybe not fracking though.
Somehow, I associated "fracking" with something plus cracking - which led me to petrochemicals.

By contrast, the one that the highest number of people got right was about sun-tan lotion protecting us from UV. Do we have advertising to thank for this?
Sun-tan lotion protects us from everything - cancer, old age, bad breath. Now with 87 per cent more snake oil.

I was expecting to see oil in the list of answers, not natural gas.
Science isn't about memorizing the "right answers". It's about being able to figure out the best approximation.

I don't know what answer I might have given to some of the questions as a kid in the 1960's.
Case in point: my memory of what I knew when I was twelve might not be accurate.

Metric System groupies and scientific literacy
Catholic Scientist writes:
The metric system is just so much better than ours....
I've always argued against the metric system being "better" than another system of weights and measures. It's just different. Its only redeeming feature, as far as I'm concerned, is the fact that it is nearly universal - and here in Canada we're influenced almost as much by the American system as by "our own" anyway.

Its obviously better to base things off of powers of 10 than some random factor. You can do the math in your head, you can convert left and right.
The other side of that coin is that it's easier to make mistakes lke dividing by a hundred instead of ten. A system that requires you to think is not "obviously" inferior.
Simpler isn't necessarily better. Every year before Christmas and Father's Day, you see those commercials for supertools that can replace a whole toolbox full of conventional tools. The trouble is that a tool that can be used for everything is seldom really good at any of them.

Predominantly?
If you can't make up your mind which system you're using, it doesn't matter how good the system is.

... it's easier to divide by a hundred and get the right answer than it is to divide by 5280 and get the right answer.
That was my point: it's too easy. It's easier to make mistakes when you don't have to think about what you're doing.
I'm not arguing that the Imperial system is better. I'm just saying that the metric system isn't intrinsically better. It may be better for some things but it isn't necessarily better across the board. That's why we still use Imperial measures for a lot of things when they're more convenient.
Dr Adequate writes:
Arguing by analogy is like using a giraffe as a can-opener.
Again you make my point. A giraffe is better for opening cans than a pillow. A stand-alone can-opener may be ideal for opening cans but it doesn't make a good pet. No single thing (or system) is all things to all men.

I recall paying 50.9 cents per half-gallon at a lonely gas station in the Fraser Canyon. I think it was 1977.

Re: Metric System groupies and scientific literacy
NoNukes writes:
Your argument here seems to be that finding imperial system conversion factors is difficult enough that a person who who wants to convert from feet to miles is more likely to find the correct conversion factor than when converting from, say meters to kilometers.
My argument is really from the opposite direction: that people using easy conversion factors are more likely to be careless with them.

There is a metric unit that is conveniently sized for any task.
And yet we don't use them. Hmm....
Convenience is as convenience does.

How often do you need to subdivide exactly one foot?
You can buy a metric tape measure but you can't buy a metric two-by-four to measure with it.
