2 We can use could, couldn't or was/were (not) able to to describe 'general ability in the past':
I could (I was able to) run very fast when I was a boy. (i.e. general ability)
3 We use was/were able to or managed to (Not "could*) to describe the successful completion
of a specific action:

Write:
'Can/could' with verbs of perception: 'I can see' [> LEG Э.З, НИЗ, APP 38.4]
1 Verbs of perception are verbs like see, hear, smell, etc. [> 9.1 C]
2 When we are describing something that is happening now, we do not use the progressive with
these verbs: I see a bird in that tree. (Not "I'm seeing")
3 We often use can + verb in place of the simple present with verbs of perception:
I can see a bird in that tree. (= I see) Can you see it? (= Do you see)
We often use could + verb in place of the simple past with verbs of perception:
I looked up, but couldn't see anything. (= didn't see)
