What is a non example of propaganda
Jobisdone [24]

Answer:

Propaganda is some information, like a poster or newspaper article or leaflet or tv broadcast etc, which only gives one very strong point of view to try to influence people to a certain way of thinking.

So, NON propaganda is something in these media which tells only the truth and gives a balanced view, or explains that there are different opinions about something, or which just doesn't try to give any opinion at all.

So, a leaflet which is an instruction sheet for a washing machine is not propaganda.  A newspaper article about a big hurricane is not usually propaganda if it just describes the effects of the hurricane.  A poster reminding people to vote in an election but which doesn't try to tell them who to vote for is not propaganda.  A TV show about cooking is not propaganda.

Read the excerpt from "A Modest Proposal."
Annette [7]

The answer is: He states that sending children to the butcher would be as simple as “roasting pigs.”

An understatement is a statement that presents something as being less relevant, less important or smaller than it actually is.

In this case, the understatement is that roasting children is just as simple as roasting pigs. Swift, the author of <em>A modest Proposal, </em>is a master of satire and the many uses that it acquires, this being one. This essay is a perfect example of his satire. In it, Swift recommends that Irish children be put to death and fed to the rich people in order to ease the latter´s big appetite and “help” the Irish alleviate their poverty by selling off their children as food.
