I want a critical summary of the story " A Modest Proposal"a detailed summmary which will help me to answer any type of question based on this story..

I have to assume you are actually talking about the essay
by Jonathan Swift, so here is a summary, there is a far more detailed and lengthy
summary at either of the two links below.

Swift wrote the
essay in response to the Irish Potato Famine and the incredible deprivations taking
place in Ireland along with what he thought was general English indifference to the
problem.

His basic proposal is that Irish babies be
fattened up and then sold as food in order to no longer burden their parents with their
feeding after the first year and to provide a means of modest income for the families
along with an entirely new industry around the production, manufacture and processing of
said babies.

It is of course a satire, considered one of
the finest examples of this type of work and often used as an example to explain what
satire is.
