worry/ worrying + one blank

[Anonymous]

-Have you fixed the (whatever)?
-Why does it worry you so much?/ Why is it worying you so much?
(Which is correct?)

And one more:
He never gets home before ten and it _____ much later than that.
My suggestions: often happens, is often.

Could you please help me?

-Have you fixed the (whatever)? (OK).
-Why does it worry you so much?/ Why is it worrying you so much?
(Which is correct?) (Both are OK).

And one more:
He never gets home before ten and often /it _is often__/ much later than that.

-Why does it worry you so much?/ Why is it worrying you so much?
(Which is correct?) (Both are OK).

What's the difference, then?
It's a present simple/ continuous exercise and I don't know what they mean.


He never gets home before ten and often /it _is often__/ much later than that.

So, if there has to be "it" after "and," the correct version is "and it is often much later than that," right?

Thanks.

Usually, the simple tense is used to indicate habitual actions.
Example: I exercise every morning.
Th continuous tense means that something is in progress.
Example: I am exercising right now; please answer the phone.
In the case of the verb, worry, there is very little difference between the simple present and the continuous present because "worry" is, by definition, something that goes on and on, something that keeps nagging at you. If you think of "worry" as something that happens in episodes, then use the simple tense. If you think of it as something that is happening at the moment, use the continuous tense).

Yes, that's right.
