Plz some scientists gaze into outer space to look for answers. some scientists seek answers in the depths of the sea. when georg steinhauser wanted answers, he looked within himself. well, he looked within his bellybutton to be exact. the austrian chemist spent three years researching the contents of his navel and the navels of others. he has solved one of life's greatest mysteries. we now know exactly what bellybutton lint contains! steinhauser presented his findings in the online version of the journal medical hypotheses. the vienna university scientist analyzed over 500 samples to determine the exact makeup of the lint. as suspected, most of the lint was made up of cotton from clothing. the fabric pieces are not alone, though. steinhauser found that the average bellybutton also contained pieces of dead skin, sweat, dust, and fat. steinhauser's notes also explained how lint accumulates. stomach hairs tend to grow in a circular pattern around the bellybutton. the hairs act like small hooks, capturing and holding contents within. shaving stomach hair can lead to a lint-free bellybutton, but don't act too hastily. although the contents of your navel may be a nuisance, research suggests that lint has a purpose. it is nature's way of protecting your bellybutton from germs and unwanted objects.

Padma has written a paper on the effects of the black death, a plague that struck europe in 1347 and killed millions of people. she focused on three major results of the plague: • a smaller population after the plague led to higher wages and greater independence for workers. • the power of the catholic church weakened because so many members had died and others had lost their faith. • a lack of farm workers led more people to raise livestock rather than planting crops, changing the european diet. read her conclusion: it does not seem right to say that an experience as horrifying as the black death had any “good” sides. still, the changes that followed the plague improved the lives of peasants. people who had previously lived in poverty, forced to work for a single employer, now had higher wages and the freedom to change jobs. even so, the continent had been devastated and would take many years to recover. which statement best evaluates her conclusion? a. the conclusion effectively summarizes all the writer’s main points. b. the conclusion is engaging, but it introduces an unnecessary new idea. c. the conclusion is engaging, but only summarizes one of the writer’s points. d. the conclusion is engaging but it does not summarize any of the writer’s main points.
