Article: Half a year ago I came across a book called"Salt,Sugar and Fat. How the Food Giants Hooked US",but finished it only recently. I am far from being a fan of junk food,over-salty,or over-sweet stuff,and honestly this food doesn't appeal to me at all. Maybe it is related to the fact that I grew up in Russia and at that time we were not so exposed to the foreign, especially made in America foods. We knew Coca Cola,Pepsi,juice powder and Cheetos,but this stuff was not so cheap or available to buy it every day and we couldn't buy them in large quantities. We didn't know the word"fat"was not a bad thing but a normal of life for some people. We always had sweets and especially on holidays they were served as a dessert along with a cake. Russians like eating sweets when they drink tea. Even with my passion to desserts I still can'trelate myself to the people Michale Moss was writing about, those consumers who could not say"no" when it came to junk food. What I found interesting in the book was that the author didn't focus on diets, necessity to exercise,sleep well at night and all other things we all are pretty aware of. The aim was not to teach people how to live but instead,after having made a huge research,interviewed more than 100 people in the food industry,Moss reveals the ugly of the food business. It puts all the facts in front of us and offers a choice:to buy or not to buy. However,the answer was known at the very beginning. Moss mentions the well-known food like Coca,Cola,Pepsi,Nestle and some others and tells how skillfully the consumers can be cheated when it comes to choosing what to put in the food basket in the supermarket. We like this taste of a chocolate,the crispy chips,and sweet porridges because it was all put on test by groups of scientists who made experiments to reveal what kind of taste will be most appealing to us. It involves brain,of course. Apart from scientific researches, it was also due to successful marketing strategies and plans that people prefer to buy food. In this companies'money... Question: The author wrote the passage mainly to _ . Yes or no, is the answer "recommend the book written by Moss"?

No

Article: If doctors want to test you for something, they'll usually take a blood or urine sample . But wouldn't it be much more convenient if they just asked you to breathe through a special instrument? In fact, your breath can say a lot about you. In traditional Chinese medicine, doctors draw a conclusion about the health state of a patient based on the smell of his or her breath; trained dogs and rats can identify the smells of the breaths of people suffering from certain cancers; traffic police also monitor drivers' alcohol consumption by testing their breaths. Just like blood and urine, your breath contains lots of " metabolites " --- the waste chemicals that the body produces, which vary from person to person. They are like personal health fingerprints, which is why scientists sometimes call them " breath prints", according to Science Daily. Compared to blood or urine testing, breath testing takes only seconds instead of hours, and it requires neither a needle nor a container to hold the body fluids . This means the test can be taken frequently to better detect early signs of diseases and monitor the progress of a medical treatment. On the other hand, as an identifier, you might think that breaths are not as reliable as fingerprints since they might change based on what you eat. However, researchers in Zurich, Switzerland mapped 11 healthy volunteers' chemical patterns by having them breathe through a special instrument, and they found that each pattern was unique and the patterns didn't change much throughout the day, reported BBC. "Our goal is to develop breath analysis to the point where it becomes competitive with the established analysis of blood and urine," said Malcolm Kohler, professor at the University Hospital Zurich. Question: According to the text we know that _ . Yes or no, is the answer "doctors can test one's breath to find about his illness"?
(Answer)
No
