Answer:
1. Tampoco.
2. Algún.
3. Nunca.
4. Ninguna.
5. Alguien.
Explanation:
In this exercise you have to complete the blanks with the correct missing words. To do that you have to pay attention to the context.
For example:
1. No me gustan los videojuegos y, por suerte, a mi novio tampoco.
This is a negative sentence so you require a word that can be used with negative sentences like the word "tampoco". The word "también" is used with positive sentences. Then, the word "ni" is used with negative comparisons.
2. ¿Te acuerdas de algún maestro de la escuela primaria (elementary school)? alguien algún alguno
This is a question sentence and we have to complete the blank with an indefinite determiner like "algún". So "alguien" can't fill the blank because it is a pronoun. Then, "alguno" is an indefinite determiner, however, it can't be used in this case owing to the fact that the word "alguno" is defining the gender in some way. So it is not correct to say in Spanish "alguno maestro".
3. Marisa no sale nunca a la calle sin maquillarse. nunca siempre también
This is a negative sentence so it requires a negative word like "nunca". So "siempre" and "también" can't be used in this case because they are used with positive sentences.
4. Usted está confundida, señorita. Ninguna de mis hermanas se llama Amalia.
In this case the sentence requires a femele word because he/she is talking about his or her sisters. So the missing word here is "ninguna" and the words "ningún" and "ninguno" can't be used in this case.
5. ¿Te puedo ayudar? ¿Buscas a alguien en especial?
This is a positive question so "ningún" can't be used here. "Algún" can't be used here. So the answer is "alguien".
