How can I correct this: "Other colonies couldn't agree whether or not to support Boston after the passage of the Intolerable Acts."this is false...

There are many correct statements that would be connected
to the Intolerable Acts and the reaction of the other colonies -- it just depends on how
specific and detailed you want to be.

For example, you
could simply say that "The other colonies strongly supported Boston after the passage of
the Intolerable Acts."

If you wanted to be more specific,
you could say "The other colonies supported Boston so much that flags were flown at half
mast when the Boston Port Act went into effect and various other colonies sent food to
Boston to help Bostonians get by."

If you want to look at
the big picture, you could even say "The other colonies were so united in their
opposition to the Intolerable Acts that they called the Continental Congress that
started meeting in 1774."

All of these are true statements
and are related to the statement that you gave.
