Prior to vs. before


#1

Hello teachers,

Please see the sentence bellow:

[color=blue]Dinosaurs became extinct sixty-four million years … first people were ever appeared on earth.

1/ prior to the
2/ before the

Which one is the correct answer? And why?

Thanks in advance

Prior to something: prior to your departure (‘prior to’ cannot be followed by a clause).

Before something or
before + clause: before you leave

Will that help you find the correct answer?
