Seriously, lots of these questions are ambiguous to educated people: > The center of the earth is very hot Not it's not. Stars are way hotter. > Does the Earth go around the Sun, or does the Sun go around the Earth? Yes. Both? Neither? Depends on which point of view is the most useful. > The universe began with a huge explosion No. It did not. The universe expanded. It is a huge difference. > It is the father’s gene that decides whether the baby is a boy or a girl What is "this gene" you're talking about? Are you sure you now the difference between a gene and chromosome? > Human beings, as we know them today, developed from earlier species of animals This is way more ambiguous that you may think: from this statement, you could infer the theory evolution or something totally stupid. Additionally, other questions are just made to be answered wrong for common people. > The continents have been moving their location for millions of years and will continue to move The question is long, there must be a trick somewhere, I'll answer no just in case. > All radioactivity is man-made I have heard that bananas were radioactive too, but I guess that's not so important so this is not what this question is about, right? > Electrons are smaller than atoms Err… whatever, I'll just guess. > Lasers work by focusing sound waves Lasers is dangerous light. I don't know how they are made though and this explanation sounds sciency, why not? And just as a bonus: > Antibiotics kill viruses as well as bacteria You do know that viruses are not commonly considered as living beings, right? Using "kill" make it so that you don't know what the question is about anymore. tl;dr: these questions were just selected to trick people into answering wrong, I would say they were other questions whose results shown opposite trends (due to randomness), but were not disruptive anough for the article
