Explanation:

Para clasificar las oraciones, debemos identificar comparativos (palabras como "more", "than" para comparar dos elementos) y superlativos (palabras como "most", "the + adjetivo en superlativo" para señalar el extremo de un grupo).

• SENTENCE CONTAINS A COMPARATIVE:
• "One of the more difficult obstacles is financing development projects." (usa "more" para comparar dificultad).
• "Some urban leaders consider providing proper utility and sanitation services an even more difficult task than adequate housing." (usa "more... than" para comparar tareas).
• "The first step with city planning is to clearly define the needs, determining which problems are worse than others." (usa "worse than" para comparar problemas).
• "City planners organize the needs into specific goals to determine what actions will give more complete solutions." (usa "more" para comparar soluciones).

• SENTENCE CONTAINS A SUPERLATIVE:
• "One of the most frustrating problems with city planning remains adequate housing." (usa "most" para señalar el problema más frustrante).
• "The most influential pioneer in city planning was Ebenezer Howard." (usa "most" para señalar el pionero más influyente).
• "The hardest step focuses on producing the means with which to fix the problems that have been identified." (usa "hardest" para señalar el paso más difícil).
• "Ancient Athens might have been the most beautiful city ever built." (ejemplo dado, usa "most" como superlativo).

Las oraciones sin comparativo/superlativo ("Taxes provide most of the money." - "most" aquí es cuantitativo, no superlativo de calidad; "As cities grow larger..." - "larger" es comparativo pero la oración es el ejemplo, no una de las opciones a clasificar) se quedan fuera de estas categorías.
