Answer:
two rounds
Step-by-step explanation:
In systems where there are two-round election, the first round is held with all fit candidates. If no candidate gets more than half of the votes (50% + 1), a second round shall be taken, that is, a second vote between the two top-ranked candidates in the first round. Thus, citizens must vote again to make their choice between the two candidates. In Brazil, for example, there are two-round elections.
