the stories‚ “The Perks of Being a Wallflower”‚ by Stephen Chbosky‚ and “A & P”‚ by John Updike‚ the two stories very similarly relay the ways that people seek to find greater understanding of themselves in the most confusing‚ chaotic times. This is just one prime example of a strong resemblance between these two stories. As the reader‚ the theme and symbolism of these stories share many commonalities. In both “A & P” and “The Perks of Being a Wallflower”‚ the relevant theme expressed amongst both

Essential Fatty Acids (EFAs) are fats that are required by the human body‚ but cannot be made by the body; therefore they must be obtained from external forces such as food. EFAs are the building blocks of all fats and oils and are required for both metabolic processes and for fuel. EFAs form the main component in the fats carried in our blood stream (triglycerides)‚ fats stored in our bodies and of cell membranes (phospholipids). (Erasmus‚ 1993)‚ (Wikipedia‚ Essential Fatty Acids‚ 2012) Two fundamental

Acid Rains There are three gases which could cause acid rain‚ which are Sulphur Dioxide (sulphuric acid)‚ NOx (oxides of nitrogen which produce nitric acid) and also perhaps Carbon Dioxide (weak carbonic acid)‚ produces these acids because these gases dissolve in rain water/ precipitation and this forms a weak version of the acid‚ as the gases dissolve it lowers the pH of the rainwater. I think that there has been a increase in the production of acid rain‚ due to the fact that the country as a

A&P Updike wrote A&P using Sammy as the protagonist and as an example of an unreliable narrator. He did not want the reader to mistake Sammy’s voice and thoughts for his own although he wrote the short story in first person narration. An example of it is that Sammy in the story said “once you begin a gesture‚ its fatal not to go through with it.” This is not Updike talking personally‚ this is what Sammy feels is right. Sammy is descriptive and observes everyone in the A&P. He described
