Why do we use present perfect in this sentence: "Do you know how many people have walked on the moon?"
Does the present perfect show that the action might happen again, although it is not an ordinary thing?
In a sentence like "Portugal was/has been the most powerful country in the world", which one is correct? Because Portugal once was it, and it could be it again, but that is almost impossible to predict.
Thanks
