复 = 𠂉 + 日 + 夂 : Mnemonic symbol: a photocopier.

復 = 复 + 彳 : Mnemonic symbol: a shrine of rejuvenation.

Frieda Fox (fu) only has an old photocopy (复) of her favorite black sneaker (彳). She restores (復) her sneakers to the original state by putting the old photocopy into the shrine of rejuvenation (復) in the space station's bathroom (Ø4).

试 = 式 + 讠 : Sherlock Holmes is doing an eye examination with the goth in the space station's bathroom. Sherlock set up a table with differently sized letters on an advertising column and has the goth read out the letters.
