From the same link as given in the OP. Let’s look at the questions themselves:
No problem with the first two.
Stupid wording. I might have gotten this one wrong if I were reading into it too deeply. Plants don’t produce oxygen atoms; they convernt oxygen-containing molecules into molecular oxygen. “Comes from plants” is at best a phrase suited for grade school kids.
No problems with these, either. I would consider the question about genes a little harder than the rest. I would have had to think about it for a second.
I knew this from working in the drug industry, but I would hardly consider it shameful for the average person not to know this.
A question like this (as well as those about evolution have a political component in that many people understand both sides of the issue but nevertheless choose to support Biblical cosmology. They may even feel it is betraying their belief system to answer otherwise on the test. Hence, the questions are loaded and are not going to reflect accurately people’s real levels of understanding. A better wording would be, “Mainstream science holds that…” or something like that.
Is it just millions or is it actually at least a billion? Also “moving their location” is a subliterate phrase. Poor.
Same deal.
Again, childish and imprecise. Not all lung cancer is caused by smoking, and smoking doesn’t always cause it. “Smoking is a risk factor for cancer and a probable cause for any individual’s case of lung cancer,” etc., would be more correct.
Same deal.
Another stupid question. Why on earth would milk be radioactive? If it were indeed contaminated with radioactivity for some reason (as in a doomsday scenario) yet not enough to make it dangerous to drink (radioactive to what degree?), it may indeed be wise to boil it just in case it was contaminated otherwise.
No problem.
I agree with Bricker that this is poor. “Go around” as a phrase is not the right trigger for the answer they want. They are looking for scientific smarts yet are asking these questions in kiddie language; for that reason one would expect some people to get confused.
Again, using the terms “rotates” and “revolves” as applicable are more likely to trigger the correct memories, as that is how people learn these things in school.
Who knows how they are grading people on these answers? If someone responds, “DNA is Deoxyribonucleic Acid,” does that count? What if they misspell that? I don’t trust these people to grade fairly, frankly.
In short, a pretty rough hodgepodge of questions: some harder, some obviously easy, some with political baggage, and some worded extremely poorly. I think the test makers should examine their own levels of skill and understanding before judging others’ too harshly.
