Explanation:

In this exercise there are some missing words you have to complete. To do that you must pay attention to the words around the missing words.

For example:

1. "Computación" is a subject so the missing word could be another subject like "matemática", "química", "física", etc. So the following missing word must be "the homework".

2. In this sentence we require an adverb like "cerca" (near).

3. In this case we require a preposition like "entre" (between) to say "he likes to be between the clock and the door".

4. In this sentence we require the verbs "hablar" (speak) and "hear" (escuchar) because we assume that "hear" and "talk" are things that you do when you are on the phone.

5. In this case "la librería" is the best option owing to the fact that sentence number 6 starts with the noun phrase "la librería" so we assume that both sentences are connected.

6. In this case we require the preposition "next to" because "la librería está al lado de la biblioteca".
