Dear 103.21.126.45:

You changed the crystal clear (although perhaps inelegant) table

A B A and B A or B
False False False False
False Unknown False Unknown
False True False True
Unknown False False Unknown
Unknown Unknown Unknown Unknown
Unknown True Unknown True
True False False True
True Unknown Unknown True
True True True True

into

AND True False Unknown
True True False Unknown
False False False False
Unknown Unknown False Unknown
OR True False Unknown
True True True True
False True False Unknown
Unknown True Unknown Unknown

Unfortunately, you have added no explanation for how to interpret the new tables, so the change is pedagogically insensitive to readers who may not know how to interpret them. What are the rows? The columns? What do the interior elements of the matrix represent? Those headers were useful!

I think you should perhaps change it back to the prevision exposition that spelled out the truth values in a way that most everyone will understand.

Best regards,
