Rigged test. #3 Requires obscure philatelist knowledge, not scientific.
That objection is overruled by the test being called a “literacy” test. It’s not a test of competency.
Tests like this are, perhaps entertaining, but if this is meant as a serious indicator of national scientific competency it is wrong. Scientific competence is a combination of logical reasoning, a creative approach to developing explanations for phenomena that are not understood, and sound theorectical and/or experimental technique. Calculus applied to basic physics problems applying fundamental principles (Newton's laws, conservation of energy, and similar) is a much better demonstration of scientific capability.
You mean number 4 and you only need to know about dinosaurs and how they were named years ago.
