When an amendment is ratified by three-fourths of congress or by three-fourths of state legislatures, it becomes part of the federal constitution, and all states—even those that did not ratify the amendment—must follow the laws in the new amendment.

true or false

FALSE

An amendment cannot be enacted just by Congress OR by state ratification, as the statement uses the word "or."   An amendment must first be approved by Congress AND then ALSO must be ratified by the states.

There's also an error in the percentages.  An amendment must be approved by a TWO-THIRDS vote in both houses of Congress  (not three-fourths).  It is correct that three-fourths of state legislatures then must ratify the amendment  in order for it to become a part of the federal Constitution.
