a chemist for a paint company conducted an experiment to investigate whether a new outdoor paint will last longer than the older

paint. fifty blocks made from the same wood were randomly assigned to be painted with either the new paint or the old paint. the blocks were placed into a weather-controlled room that simulated extreme weather conditions such as ice, temperature, wind, and sleet. after one month in the room, the blocks were removed, and each block was rated on texture, shine, brightness of color, and chipping. the results showed that the blocks painted with the new paint generally had higher ratings than the blocks painted with the old paint. however, an analysis of the results found that the difference in ratings was not statistically significant. what can be concluded from the experiment?

Compare and contrast the story called THE TELL-TALE HEART?
ExtremeBDS [4]

Answer:

Short stories are favorites of readers who don’t want to commit to a full book, and Edgar Allan Poe is a favorite author among them. One of Poe’s more known stories is “The Tell-Tale Heart”, which is about how a man murdered his older housemate and was then overwhelmed by the dead man’s heartbeat of guilt. The original version has greater impact than the rewritten version because, although similar in pacing and plot, the differences of writing style and characterization between the versions affects readers more. For the first example, both the original and rewritten versions of “The Tell-Tale Heart” share literary devices such as pacing and a similar plot. The original version includes,” At length it ceased. The old man was dead. I removed the bed and examined the corpse. Yes, he was stone dead.”(Poe). Poe’s use of shorter sentences demonstrates the narrator’s excitement at the death of the old man. Hemphill’s version states “All at once the lantern was thrown wide open, and I shrieked with the voice only a frail man could have if he were about be killed.”. The rewritten version includes shorter sentences similar to Poe’s that pace the story to excite the reader and to build suspense.

o-na [289]

Formal and informal language serve different purposes. The tone, the choice of words and the

way the words are put together vary between the two styles. Formal language is less personal

than informal language. It is used when writing for professional or academic purposes like

university assignments. Formal language does not use colloquialisms, contractions or first person

pronouns such as ‘I’ or ‘We’.

Informal language is more casual and spontaneous. It is used when communicating with friends or

family either in writing or in conversation. It is used when writing personal emails, text messages

and in some business correspondence. The tone of informal language is more personal than
