中考

中 = 丨 + 口 : Mnemonic symbol: a dart board, because you always try to hit the center.

Julian Giant Squid (zhu-) is throwing dinosaur bones (丨) as darts on a dart board in front of the engine ((e)ng1). To make it a bit more difficult he's throwing mandarins (口) into the air as well and skewers them up right in the center (中 is a mandarin skewered on a dinosaur bone) in mid flight with the dinosaur bones. He's still able to consistently hit the center (中) of the dart board.

考 = ⺹ + 丂 : Karl Marx (k) has to take an exam (考) in the artoa's living room (ao3). It is very difficult for him because he has to wear a breathing mask (丂) due to the open fire, and he also has to wear a huge crown (⺹) which makes it difficult for him to see the exam papers.
