I know that in many cases, a double 'that' is grammatically acceptable, but I still feel it is distracting for readers to see a 'that that' pop up in the middle of a text.
Is it acceptable to simply remove the second 'that'?
Can I say
The fact that was the only evidence available was shocking.
instead of
The fact that that was the only evidence available was shocking.
If not, how else can I avoid the double 'that'?
