How long \ past simple

Hello

I did an exercise online and the page is always English page usually dealing with tenses

1. How long ... to Terry ? She ... to him for three years.

A. has she married ... has married \

B. was she married ... was married \ C. did she marry ... married \ d. she married ... married

The correct answer according to the page is A How long was she married to Terry? She was married... to him for three years. Is not the present perfect is more suitable here ? Because there is period ( 3 years ) ?

1. When ... Bob ? She married him six years ... .

did she marry ... later \ has she married ... later

has she married ... before \ did she marry ... before

Also here choosing the past simple ( did she marry ... later ) ?

I noticed somewhere the form ( how long ) is used with the past simple, but mainly the most examples using the perfective forms
