Arguments are used to prove a certain idea or convince people of doing an action. Written arguments are recommended for formal contexts, in cases the argument involves presenting a lot of evidence or the argument is part of a complex process that involves important changes and agents. For example, in legal cases arguments are presented as texts.

According to this, the situation that would benefit from a written argument is "Proposing that your neighborhood increases the land set aside for parks" because this situation involves presenting a lot of evidence and the argument is part of a complex process as it needs to be considered by each person in the neighborhood but also authorities. On the opposite, other situations such as convincing your parents or support your best friend are informal and would benefit more from an oral argument.
