My girls are on the wait list for their preschool and it is twice as tough to get in with twins.
Marked phrase kind of puzzled me. I quoted this from a tv-series.
We don't know the second part of the "as adjective as ..." form here. Getting with twins is twice as tough compared to what? I think this is a reduced use of this form.
Mıght this be the full form ?
It is twice as tough to get in with twins as to get in with one kid.
