True or false: Macbeth orders the death of Fleance because the witches said Banquo would be father to a line of kings.true or false

A few corrections are in
order:

Yes, the statement is true, but the answer above has
it a bit backwards (probably just a proofreading error): Macbeth orders the murder of
both Banquo and his young son, Fleance. The murderers are able to complete only half of
their job: they succeed in killing Banquo, but, in the dark of night, Fleance
escapes.

This all takes place just before (or even during)
a formal dinner that King Macbeth is throwing for himself in his
castle.

Furthermore, Macbeth does not think that he will
ever have any children, so the attempted murder of Fleance is done out of jealousy of
what had been promised to Banquo by the witches.
