En la sintaxis del idioma español, se entiende por oración impersonal (o cláusula impersonal) aquella que ni tiene ni puede tener sujeto sintáctico recuperable, esto es: ... No se le puede suponer tampoco un sujeto implícito ("omitido, elíptico, elidido, tácito").
I believe it is Puedes but, I am not exactly sure. Sorry!
Answer:
All the sentences are about pass habits or events that happened in the past.
Explanation:
The sentences are describing habits in the past or activities that started and finished in the past without interruption. For example, if I say - *El cayó al suelo. Iba a ver lo que pasó.- I am saying that I was going to see what happened when suddenly he felt. Is an action that was interrupted by another action in the past.
In the case of the sentences that are describing activities in the past, it is incorrect to say, for example - *Siempre fuimos al lago durante el verano- because it is stating that this year, we also are going to the lake because we always go there during summer. What the sentence is trying to say is that we went there every summer but not anymore.
