Japanese uses three scripts, and each one coincidentally appears more prominently in one of the three problems than in the others: 1. Katakana is a sparse, alphabetic script used to transcribe sounds. Problem 1 looks sparse because much of the space is used to phonetically spell out the word "tribonacci". 2. Kanji is a dense, glyphic script used to express ideas. Problem 2 looks dense because big words like "surface area" and "twice differentiable" are translated to their native equivalents. 3. Hiragana is a sparse, alphabetic script used to add grammatical structure. Problem 3 looks sparse because of the high number of prepositions and auxiliary words like "in", "be", and "of".
