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.

a. A chemist has come up with an idea for using citrus waste to produce ethanol, which is added to gasoline to reduce air pollution.
I have found the choices to your question from another source and I will place them here:
A) All order, I've come to understand, is theoretical, unreal -- a harmless, sensible, smiling mask men slide between the two great, dark realities. B) I seize up a sleeping man, tear at him hungrily, bite through his bone-locks and suck hot, slippery blood.C) Fate often enough will spare a man if his courage holds. (162)D) As if casually, in plain sight of them all, I bit his head off, crunched through the helmet and skull with my teeth and, blood-slippery body in two hands. (79)
Among these choices, the passage that would suggest that "life is meaningless" would be option A. That passage suggests that every order is not real, that people just unknowingly go over between the "two dark realities".
It supports that life is meaningless by telling us that the order we try so much to achieve and maintain is nothing but a theoretical concept - an imagination.
