Hi,
Please take a look at these sentences and my related comments, and tell me what you think.
1. She has more money than her husband/her husband does/her husband has. -- I think all three can be used but wonder why this one can have 'her husband does' as a viable option, whereas the other two don't seem to have that option.
2, She runs faster than her husband/her husband does. -- I think both of them can be used, whereas the use of phrase "her husband has" can not.
3. She plays tennis better than he husband/her husband does. -- Similar in my assessment to no. 2.
