Answer:
a) Potential Sources of confounding:
1) Pancreatic cancer patients were being compared with persons hospitalized for cancerous diseases. Coffee may likely aggravate the pains of pancreatic cancer patients unlike other cancer patients because the latter's cancer diseases were not digestive.
2) Unintended bias was introduced by investigators in questioning patients. The investigators asked questions on coffee drinking habits of those already hospitalized. This biased the drinking of coffee as a predisposing factor.
3) There could be differences among men and women because of other habits. While drinking more coffee predisposed women to cancer, according to the confounding statements, drinking even more did not have much difference in men.
Explanation:
"CRITICS SAY COFFEE STUDY WAS FLAWED" was an article in New York Times written by Harold M. Schmeck Jr. on June 30, 1981. It attempted to critique the study of drinking coffee and its disposal to cause cancer to the drinkers.
In this article, he introduced the views of critics of the Coffee Study which was earlier published in the New England Journal of Medicine and the accompanying refutal by the researchers.

Answer:
This technique benefits me as a learner as it helps me to visualise my method and approach to solving a problem before I go about solving it. This is pertinent especially in problem based subjects like mathematics. In learning, this is also helpful in helping me to internalise the information gathered, for example, being able to mentally link the information together on a concept map in your head or on paper also helps in retaining information. This concept of visualisation and categorisation is similar to the thinking process of computational thinking which involves breaking down the problem and solving it abstractly.
I do not agree that this only works for visual learners. While visual learners tend to be more inclined to this method of processing in their minds or on paper, I feel that everyone uses this method to a certain extent although through a different methodology or thought process.
Explanation:
Answer: As the very theme of the story is the absurdity of trying to escape death, the clock serves as a reminder that death is inevitable. It symbolizes the passage of time.
Explanation:
<em>"The Masque of the Red Death"</em> is Edgar Allan Poe's short story, in which a group of thousand people, including Prince Prospero, lock themselves down in an abbey. They want to be safe during the deadly pestilence (Red Death).
In the story, The Seven Rooms of the abbey represent seven stages of life. In the Seventh Room, "against the western wall", there is "a gigantic clock of ebony." The Ebony Clock serves as a symbol of death and its inevitability, while its swinging pendulum symbolizes the passage of time. When an hour passes by, the clock chimes, and everyone listens to it, aware that they have lost an hour of their life and that death is approaching. Prince and his people could not stop the pendulum from swinging - similarly, they cannot escape death.
