Grammar explanation
We use the present perfect simple (have or has + past participle) to talk about past actions or states which are still connected to the present.
Unfinished time and states
We often use the present perfect to say what we've done in an unfinished time period, such as today, this week, this year, etc., and with expressions such as so far, until now, before, etc.
They've been on holiday twice this year.
We haven't had a lot of positive feedback so far.
I'm sure I've seen that film before.
We also use it to talk about life experiences, as our life is also an unfinished time period. We often use never in negative sentences and ever in questions.
I've worked for six different companies.
He's never won a gold medal.
Have you ever been to Australia?
We also use the present perfect to talk about unfinished states, especially with for, since and how long.
She's wanted to be a police officer since she was a child.
I haven't known him for very long.
How long have you had that phone?
Finished time and states
If we say when something happened, or we feel that that part of our life is finished, we use the past simple.
We visited Russia for the first time in 1992.
I went to three different primary schools.
Before she retired, she worked in several different countries.
We also use the past simple for finished states.
We knew all our neighbours when we were children.
I didn't like bananas for a really long time. Now I love them!
Past actions with a result in the present
We can use the present perfect to talk about a past action that has a result in the present.
He's broken his leg so he can't go on holiday.
There's been an accident on the main road, so let's take a different route.
They haven't called me, so I don't think they need me today.
Again, if we say when it happened, we use the past simple.
He broke his leg last week so he can't go on holiday.
However, we often use the present perfect with words like just, recently, already, yet and still.
We've recently started going to the gym.
She's already finished season one and now she's watching season two.

Hello brain1010,
If you say 'has kept', it communicates much the same idea and speaks about a situation up until the moment of speaking. 'is keeping' and 'has been keeping' suggest that the situation may change, whereas 'has kept' doesn't express this idea as much (though neither does it exclude the possibility).
If you have any further questions about this, could you please provide more context? What exactly tenses mean is highly contextual and so it's difficult to say for sure without knowing more.
All the best,

Hello brian1010,
I'm afraid I can't explain why the writer of these sentences chose these particular forms. I would need to know the context and their purpose and view of these situations to be able to do that.
But I'm afraid that even if I had that information, this goes well beyond the kind of service we are able to provide these days -- we simply have too many other comments that are directly related to the content on our pages and other work preparing new materials.
I'm sorry we're not able to help you more with this.
All the best,

Hello Tim,
I think saw is the natural choice here. The present perfect describes an open time period stretching up to the present (with an effect on the present), whereas since and the last time imply a finished time period.

Hello tikah,
If you say 'How long have you had the old one?', this means that you still have the old car. I suppose that is possible, but the idea here is to distinguish between the present perfect, which speaks about something that is still happening (owning the car) and the past simple, which is speaking about something that already finished.
So 'How long did you have the old one?' means that you no longer have the old car. It is now 2020; if you had the old car from 2007 to 2019, then the past simple is the best form, because it speaks about a finished past time.
All the best,

Hello angeeeeeeel,
All three of these clauses are correctly formed -- in this sense, they are all correct -- but none are a complete sentence (with a subject, verb and complement), and in this sense, none of them are correct.
The third one is probably the most appropriate for the context you mention.
All the best
