A more thorough explanation:

An office-block ballot is a type of ballot used in elections that lists the candidates' names under the title of the office sought without mentioning the candidates' party affiliations. This means that voters have to know the candidates and their positions rather than just voting for a party.

For example, if there are four candidates running for mayor, their names would be listed under the title "Mayor" without any indication of their political party. This type of ballot is used to encourage voters to focus on the qualifications and positions of the candidates rather than just voting for a particular party.

Another example of a type of ballot is the Australian ballot, which is a uniform ballot printed by the government, listing all eligible candidates, and marked in secret. This type of ballot is used to prevent voter intimidation and ensure that each vote is counted fairly.

Overall, the type of ballot used in an election can have a significant impact on the outcome and the level of voter engagement. By using an office-block ballot, voters are encouraged to make informed decisions based on the qualifications and positions of the candidates rather than just voting for a particular party.
