The correct option to complete the sentence "Quise ir a la fiesta, pero tuve que..." is option 2: Poder.
The sentence "Quise ir a la fiesta" means "I wanted to go to the party." The word "quise" comes from the verb "querer," which means "to want."
The phrase "pero tuve que" means "but I had to." The word "tuve" comes from the verb "tener," which means "to have." In this context, it means "I had." The word "que" means "that" or "to."
So, when we put it all together, the sentence "Quise ir a la fiesta, pero tuve que" translates to "I wanted to go to the party, but I had to."
Option 1, "conocer," means "to know" or "to meet." This verb doesn't fit in the context of the sentence because it doesn't convey the meaning of having to work instead of going to the party.
Option 3, "querer," means "to want." This verb is used in the first part of the sentence to express the desire to go to the party.
Option 4, "saber," means "to know." This verb doesn't fit in the context of the sentence because it doesn't convey the meaning of having to work instead of going to the party.
Remember, context is important when choosing the correct verb to complete a sentence. In this case, "poder" (to be able to) accurately conveys the meaning of not being able to go to the party because of work.
