May I ask a beginner's question?
Why are so big a percentage of Open Interest on the OTM options are not
closed at expiration? I often see over 90% remains outstanding at OE.

It's not a beginner question. related to behavior of investors.
I would guess buy OTM is speculative and aggressive in nature.
And buying back is not an attractive option for them.
90% is more than my experience.
in the whole chain, the expired worthless options is about 65%.

If you sell a call, and it become OTM at expiration, why do you want to
close it?

Your answer explains very well the Open Interest on OTM options at OE.
What about ITM options at OE. For exampple, CREE August Put @60. The OI at
close is 3,868 contracts. Considering this is a fairly liquid contract, why
would over 90% contracts wait on being assigned and becoming short positions?

Hedge purpose.
Back spread.
Reduce overall margin requirement when using the Portfolio Margin.
