Which of the following events took place during jefferson's term in office?

he increased the size of the army.
he maintained the property requirements for voting.
he increased the power of the supreme court.
he became the first president to represent the federalist party.

The correct answer is "He increased the size of the Army".

Thomas Jefferson strongly believed it was necessary to establish an educational institution for the Army, as he did not saw it feasible to import overseas engineers with "questionable loyalty" to oversee military improvements. This, in addition to the occurrence of the first  Barbary War, in which the US had to deal with Pirate ships who were assaulting American merchant ships, led to an important increase in the country's armed forces.

regarding the law, the 15th amendment was specifically designed thinking in the rights of black free men.

even though ratified on february 3, 1870, the promise of the 15th amendment would not be fully applied for a long time.poll taxes and literacy tests would allow southern states disenfranchise african americans. only in 1965 the voting rights for african americans would be actually able to vote in the south.

in 1965, president johnson signed the voting rights act, which aimed to overcome legal barriers that prevented african americans from voting as it was guaranteed by the 15th amendment to the u.s. constitution.
