The correct answer is "sucios" (dirty) because it agrees in number and gender with "los platos" and because it makes sense in context. The answer choice "rotos" (broken) wouldn't make sense because there's no reason to wash broken plates.

English translation: "The plates are dirty, so one must wash them."

Both "único" (only) and "segundo" (second) agree in number and gender with "hijo;" however, only "único" (only) fits in context, as it would not make sense for someone to say that they are an "hijo segundo" (second child) if that person is claiming not to have any siblings.

English translation: "I do not have siblings; I am an only child."

The correct answer is "peor." "Peor" is the comparative version of the adjective "mal," so "más mal" and "más peor" cannot exist in Spanish. Likewise because of the context, "la peor;" "the worst" cannot be used in a comparison, only as a superlative. "Peor" is an adjective that does not change based on gender, so "peora" is also wrong.

The correct preposition to use in this case is "en." The verb "pensar" can take many prepositions after it, each one affecting the meaning slightly. With "en" afterwards it means "about." Both "de" and "sobre" are used when "pensar" means "to have an opinion" about something. Both "con" and "a" are incorrect.
