The questions shall be printed on the ballots used at the election in substantially the following form:
“Shall the electors elect a mayor and four city council members?”
“Shall the term of office of mayor be two years?”
“Shall the term of office of mayor be four years?”
The words “Yes” and “No” and “two years” and “four years” shall be so printed on the ballots that the voters may express their choice. The term of office of mayor shall be that preferred by a majority of those voting on the proposition.
