Article: People are interested in eating raw foods or whole foods partly because eating these types of food reduces the risk of acid accumulation in our body . Raw and whole foods are usually digested more efficiently than cooked and processed foods . When we cook foods , we destroy the natural enzymes that are part of the food in its raw form . These enzymes were intended by nature to help us digest the food . When we consume food without these natural enzymes , our bodies either digest the food improperly or allow too many nutrients to be absorbed into the bloodstream . In both cases , the result is obesity . When too many nutrients are absorbed at once , the body grows fat . Processed foods contain chemical elements , which might confuse the appetite system that tells us when we've had enough to eat ; as a result , people often overeat . Processed foods also upset the digestive cycle . The body will either identify these foods as allergens and then store them safely away from the organs as fat , or the remains of undigested food will become acidic and enter the bloodstream as acid waste , which will stick to the blood vessel walls and block the passage of vital oxygen and nutrients heading for the body's cells . The body's metabolism becomes inactive , and the result is weight gain and obesity . To stop this _ circle in its tracks , people need to consume food and supplements that will balance the acid already accumulated in body . Eating the right types of raw and whole foods can help . It's also important to restore our enzyme balance . We need to identify and avoid the foods that cause acid accumulation and consume the foods that increase enzyme production . If we truly want to change and help our body heal itself , we need to take an active approach . Question: Processed foods will probably _ . Yes or no, is the answer "lead to obesity"?
Yes

Article: As goods and services improved, people were persuaded to spend their money on changing from old to new, and found the change worth the expense. When an airline equipped itself with jets, for example, its costs (and therefore air fare) would go up, but the new planes meant such an improvement that the higher cost was justified. A new car (or wireless, washing machine, electric kettle) made life so much more comfortable than the old one that the high cost of replacement was fully repaid. Manufacturers still cry their goods as persuasively as ever, but are the improvements really worth paying for? In many fields, things have now reached such a high standard of performance that further progress is very limited and very, very expensive. Airlines, for example, go to enormous expense in buying the latest jets , in which vast research costs have been spent on ly small improvements. If we abandon these vast costs we might lose the chance of cutting minutes away from flying times; but wouldn't it be better to see airfares drop dramatically, as capital costs become ly insignificant? Again, in the context of a 70 m. p. h. Limit, with lines of cars traveling so close as to control each other's speeds, improvements in performance are actually irrelevant; improvements in handling are unnecessary, as most production cars grip the road perfectly, and comfort has now reached a very high level. Small improvements here are unlikely to be worth the thousands that anybody replacing an ordinary family car every two years may have spent on them. Let us instead have cars -- or wireless, electric kettles, washing machines, television sets -- which are made to last, and not to be replaced. Significant progress is obviously a good thing, but the insignificant progression from model-change to model-change is not. Question: In the case of cars, the author advises that we _ . Yes or no, is the answer "improve their durability"?
No

Article: Everyone knows that eating too much junk food is not good to our health. Yet, what is it about junk food that is so completely irresistible ? For one thing, it's everywhere. From chips in fast food restaurants to candy in supermarkets, junk food always seems available. Thankfully, science is now providing new clues to help us reduce snacking. Make friends with dainty eaters. Studies have found that people tend to increase or reduce the amount of food they eat depending on what their companions are taking in. See happy movies... and always get the smaller bag of popcorn . According to some experts, people eat up to 29% more popcorn if they are watching a sad or serious movie, compared to when they are watching a comedy. Viewers consumed almost 200 calories more when snacking from a large bucket, as opposed to when given a medium-sized container. Eat breakfast. Nutritionists have gone back and forth about the question of how much to eat in the morning, but new studies suggest that consuming a good breakfast is a must. Surveys on long-term weight-loss show that two key factors in keeping weight down are eating breakfast and exercising. Divide your food and conquer overeating. Any kind of dividing your food into portions slows down your eating. Any kind of marker makes you aware of what you're eating and of portion size. Researchers advise reallocating snack foods into small plastic bags. It sounds simplistic, but it works. Question: Why do people eat too much junk food though it is bad for our health? Yes or no, is the answer "Because it's available here and there."?
No
