The resignation of the presidency of the Republic by Jânio Quadros, on August 25, 1961, precipitated the country into a serious political crisis. The military ministers and the most conservative political sectors were then opposed to the inauguration of the elected vice president, João Goulart. The outcome and, to some extent, the solution to the political impasse implied

a) the cassation of parliamentarians who were considered complicit in the rebellious movements in the armed forces.
b) the convocation of a Constituent Assembly that should restore the balance between the three republican powers.
c) the political reform that limited the number of parties to two large groups, the Social Democratic Party and the National Democratic Union.
d) the extinction of workers' unions that were under the control of militants of the Brazilian Communist Party.
e) the approval by Congress of a constitutional amendment that established parliamentary rule in Brazil.
