Respuesta :

Pedro learnt a lot about the line fish at the aquarium he visited yesterday, we can see it’s in the past as Oliver visited the aquarium yesterday and it wasn’t today, however you could say today and visited because this would be in the past anyway because of the word visited, if it was Oliver is visiting the aquarium this would not be in the past but we can see it’s in the past from the two words visited and yesterday,
