Lessons Wanted

The problem with this test, other than the fact that all IQ tests are culturally biased just like any other test and are falsely believed not to be, is that if I were actually very intelligent at all, I would not have bothered to keep starting the stupid test all over again every single time the page failed to load for me and I had to start all over again at the beginning.

IQ Challenge [Note: This test is a joke. See comments.]

But I have a question. Can someone please explain this pattern to me? It's the only question on the whole test that I had to guess about. I'd be happy to explain any of the other questions on the test to anyone who can't figure out the answers.



(A, B, C, and D are the answer choices. The four dots are there to separate the pattern from the answer choices; they are not part of the pattern.)
