What does the term legislate mean?
a. to write papers
b. to govern the country
c. to talk for long periods of time
d. to make laws

The correct answer is "to make laws" - answer D. You can see that it's connected to the laws because it's also the name of one of the three branches of the government (the legislative branch) which is responsible for making laws. (the other two : judicial: to judge and executive: to actually govern)

Icould be wrong but i would say b.
