Present perfect simple, yes but why? [closed]

Although very often the present perfect simple and progressive forms can be used interchangeably. Why is the simple form necessary here. "They have completely restored their home " is it because of "completely "?

Solution 1:

Without a context, it is not possible to say that the present perfect is required, necessary, needed, or should be used. The sentence is also acceptable in other tenses : " They are completely restoring their home." "They will completely restore their home." "They completely restored their home."

The only tense that is dubious from a meaning aspect is "They completely restore their home." Restore seems to be an activity verb and to me in this case feels better with a progressive aspect. This isn't to say the present aspect cannot be used with it ("They completely restore homes.") but when you add "their" it makes the sentence specific in a way that doesn't seem to support the "fact" sense of the present aspect, which is why home is plural.
