This is a basic use of comparatives.

I get these confused sometimes too
This is a basic use of comparatives.

the case does not need think... because then its mean "too or so or ....."
so (or then) the correct solution is "than"
I choice "Than"
cause : than come if be compare between something .![]()
Then is something for things after an event.
It's bigger than his.
rather .... than ....
or
rather ..... then ....?
Always easy to remember than as 'comparative' and then as 'time'
