Question

1. ¿Adónde ____________ tú. ayer? (3 points) Fuiste Fuisteis Fueron vas

Answer 1

1. The correct answer is fuiste. 
You need the preterite form of the verb IR,which for second person singular (TU) is FUISTE. Fuisteis is used for second person plural, and fueron for third person plural. Vas is also incorrect because the sentence says 'ayer,' which means yesterday, so you need a past tense, and VAS is in present.

3. Yo pagué en la recepcion.
This sentence means - I paid at the reception. El balcon is a balcony, el ascensor is the elevator, and la llave is a key. So obviously none of those options make any sense here, which means that la recepcion is the correct answer.

4. ¿Adónde fueron Uds. ayer? 
You need the preterite form of the verb IR,which for the third person plural (USTEDES) is FUERON. Fuimos is used for first person plural. Vamos and van are also incorrect because the sentence says 'ayer,' which means yesterday, so you need a past tense, and both VAMOS and VAN are in present. 

5. Yo subí a la habitación en el ascensor.
This sentence means - I went to my room using the elevator. La cancha de tenis is a tennis court, el balcon is a balcony, and la recepcion is the reception. So, obviously none of those options make any sense, which is why el ascensor is correct.

7. Marta y Julia leyeron un libro anoche.
You need the preterite form of the verb LEER, which for the third person plural (Marta y Julia) is LEYERON. Leimos is used for first person plural, and leyo is used for third person singular. Van a leer is also incorrect because the sentence says 'anoche,' which means last night, so you need a past tense, and VAN A LEER is in future. 

8. Juan y Pablo escribieron una carta anoche.
You need the preterite form of the verb ESCRIBIR, which for the third person plural (Juan y Pablo) is ESCRIBIERON. Escribimos is used for first person plural, and escribio is used for third person singular. Van a escribir is also incorrect because the sentence says 'anoche,' which means last night, so you need a past tense, and VAN A ESCRIBIR is in future. 

9. Ayer yo lavé los platos. 
You need the preterite form of the verb LAVAR, which for the first person singular (yo) is lavé. Lavó is used for third person singular. Voy a lavar and lavo are also incorrect because the sentence says 'ayer,' which means yesterday, so you need a past tense, and Voy a lavar is in future, whereas lavo is in present.

10. Ayer nosotros comimos en un restaurante famoso. 
You need the preterite form of the verb COMER, which for the first person plural (nosotros) is COMIMOS. Comemos is incorrect because it represents the present, when you need the past form (because of ayer, which means yesterday). Comen is the wrong person, because it is used for third person plural. Comeremos is also incorrect because it is in the future.

11. Ayer yo planché la ropa. 
You need the preterite form of the verb PLANCHAR, which for the first person singular (yo) is planché . Planchó is used for third person singular. Voy a planchar and plancho are also incorrect because the sentence says 'ayer,' which means yesterday, so you need a past tense, and Voy a planchar is in future, whereas plancho is in present.

13. Ayer nosotros nadamos en una piscina grande.
You need the preterite form of the verb NADAR, which for the first person plural (nosotros) is NADAMOS. Nadan is the wrong person, because it is used for third person plural. Vamos a nadar and naderemos are both wrong because they are in the future, and we need the past form because of ayer, which means yesterday.

14. ¿Qué hiciste tú ayer?
You need the preterite form of the verb HACER,which for second person singular (TU) is HICISTE. All other options are incorrect because wrong tense is used - hacen and haces are in the present, and vas a hacer is in the future, when we need the past because of ayer.

16. ¿Qué compraste tú en el mercado ayer?
You need the preterite form of the verb COMPRAR, which for second person singular (TU) is COMPRASTE. All other options are incorrect because wrong tense is used - compran and compras are in the present, and vas a comprar is in the future, when we need the past because of ayer.

17. True. A single room indeed has only one bed. However, this bed can be a regular one, or a king-sized bed for two people. Ultimately, there is only one bed although two people may sleep in it.

18. False. A double room doesn't have three beds, but rather two. The sentence would say 'La habitacion triple tiene tres camas' if there were three beds - triple means three, whereas doble means two.
