Problem: Given the question: Write a multi-choice question for the following article: Article: In my experience, one of the greatest reasons of unhappiness is the difficulty we have in accepting things as they are.When we see something we don't like, we wish it could be different-we cry out for something better.That may be human nature, or perhaps it's something that has been grown in our culture. The root of the unhappiness isn't that we want things to be different, however, it's that we decided we didn't like it in the first place.We've judged it as bad, rather than saying, "It's not bad or good, but it just is." Here is an example.I have written a paper, A Beautiful Method to Find Peace of Mind.Quite a few people think it bad after reading it because I think people should expect things to go differently than you planned, and that you should accept that, instead of encouraging people to change themselves or the environment as much as possible.You could accept it as the way the world works-as the way things actually are.And try to understand why that is, and follow it, as it is. This can be useful to whatever you do: whether it be how other people act at work, how politics works and how depressing the news media can be.Accept these things as they are, and try to understand why they're that way. It'll save you a lot of sadness because you'll no longer say, "Oh, I wish things didn't go bad!" If you really understand what I mean, you can try a different way to live in this world:accept, and understand.It might lead to some interesting results.

Problem: Given the question: Write a multi-choice question for the following article: Article: Elderly women who eat foods higher in potassium are less likely to have strokes and die than women who eat less potassium-rich foods, according to new research in the American Heart Association. "Previous studies have shown that potassium consumption may lower blood pressure. But whether potassium intake could prevent stroke or death wasn't clear," said Smoller, professor of the department of population health at Albert Einstein College of Medicine, Bronx, NY. Researchers studied 90,137 women, aged from 50 to 79 for an average 11 years. They looked at how much potassium the women consumed, as well as if they had strokes, including ischemic strokes , or died during the study period. Women in the study were stroke-free at the start and their average dietary potassium intake was 2,611 mg/day. Results of this study are based on potassium from food, not supplements. The researchers found: Women who ate the most potassium were 12 percent less likely to suffer stroke in general and 16 percent less likely to suffer an ischemic stroke than women who ate the least. Women who ate the most potassium were 10 percent less likely to die than those who ate the least. Among women who did not have high blood pressure, those who ate the most potassium had a 27 percent lower ischemic stroke risk and 21 perc ent reduced risk for all stroke types, compared to women who ate the least potassium in their daily diets. Among women with high blood pressure, those who ate the most potassium had a lower risk of death, but potassium intake did not lower their stroke risk. "Our findings suggest that women need to eat more p otassium-rich foods. You won't find high potassium in junk food. Some foods rich in potassium include white and sweet potatoes, bananas and white beans." The U.S. Department of Agriculture recommends that women eat at least 4,700 mg of potassium daily. "Only 2.8 percent of women in our study met or went beyond this level. The World Health Organization's daily potassium recommendation for women is lower, at 3,510...
