Explanation:

Question 1

To solve this, we first identify the opposite of "sucia" (dirty), which is "limpia" (clean). Then, we determine the correct verb: "estar" is used for temporary states or conditions of a place (like a room's cleanliness). The subject "mi habitación" is singular feminine, so the correct form of "estar" is "está".

The opposite of "contento" (happy) is "triste" (sad). The subject "mis padres" is plural, and we use "estar" for temporary emotional states. The plural form of "estar" is "están".

For "alto" (tall), the opposite is "bajo" (short); for "moreno" (dark - haired), the opposite is "rubio" (blond). The subject "tú" uses the verb "ser" (for inherent characteristics like height and hair color). The form of "ser" for "tú" is "eres".

Answer:

está; limpia
