Article: If you've ever seen the way dog people interacted with their pets, it comes as no surprise that there's some germ-exchanging going on there. A new study indicates that dog ownership specifically may be one of the biggest single contributors to what kinds of microbes live on your skin. A team of researchers led by Se Jin Song at the University of Colorado, Boulder, took swabs of the tongues, palms, forehead and feces of members of 60 family households. Some of the families had children or household pets and some did not; dogs were the only pets swabbed. Researchers then analyzed the DNA of the bacteria they found to determine how diverse the bacteria populations were. Not surprisingly, family members who lived together had more bacteria in common than members of separate households. Bacteria on the skin were especially similar within households, probably because we pass microbes through the air, through direct contact, and via the surfaces we touch. The most surprising finding, however, was the large bacteria contribution Fidonad made. The skin bacteria of dog owners from different households was almost as similar as if they'd cohabited without a dog. Put another way, you and a friend across town who both own dogs share a skin ecosystem as alike as a married couple does. The reason for this appears to be that dogs harbor some kinds of bacteria that are rare on human skin. One in particular, a family of bacteria called Methylophilaceae, was abundant in the mouths of dogs sampled as well as the skin of their owners--indicating "a common occurrence of oral-skin transfer between dogs and their owners," according to the results published in the journal eLife. Question: The research took the following factors into consideration EXCEPT _ Yes or no, is the answer "dogs being the only pets in the households."?
No

Article: About 1 in 15 households drink bottled water today, spending about $ 4 billion a year on it. Although the reasons for the trend are many, bottled water's health benefits fall near the top of the list. Surveys have found that about 25 percent of bottled water drinkers choose the beverage for health and safety reasons; another quarter believe it is pure and free of contaminants . Regardless of its pristine image, bottled water is not necessarily any purer or more healthful than what flows right out of the tap. Consider that the Food and Drug Administration (FDA), the bottled water industry watchdog, does not require that bottled water meet higher standards for quality, such as the maximum level of contaminants, than public water supplies regulated by the EPA. For the most part, the FDA simply follows EPA's regulatory lead. Granted, bottled water is often filtered to remove chemicals such as chlorine that may impart a certain taste. But that doesn't make it any safer. In fact, about 25 to 40 percent of bottled water comes from the same municipal water supplies as tap water. Furthermore, some bottled waters do not contain any or enough of the fluoride needed to fight cavities. The only way to determine whether a certain water contains the mineral is to check with the company that bottles it. This is not to say that bottled water is necessarily any better or worse, from a health standpoint, than tap water. It's certainly preferable to tap water for those who like its taste. The problem is that many consumers pay 300 to 1,200 times more per gallon for bottled water than for tap water because they think bottled water is the more healthful of the two. Bottlers add to the confusion by sprinkling terms such as "pure", "crystal pure" and "premium" on labels illustrated with pictures of glaciers, mountain streams, and waterfalls, even when the water inside comes from a public reservoir. However, the FDA has set forth regulations requiring clear labeling of bottled waters. The mini glossary of bottled waters explains... Question: What's the main idea of this passage? Yes or no, is the answer "Consumers should consider carefully the reason for buying bottled water."?
