Middle born children will tell you that they usually didn't feel all that special while growing up. The first born had his spot- carrier of the family banner and responsible for everything. The last born had his comfy little role, but the middle born had no distinctive place to call his own.
Middle-borns just seem to be easily overlooked, and maybe that's why there are so few pictures of them in the family photo album. There may be hundreds, seemingly thousands, of pictures of the firstborn. For some strange reason, however, which I have confirmed by polling middle-born children around the world, there are seldom many pictures of the middle child, and what photos there are have him included with the others—squeezed again between the older sibling and the younger sibling.
Another thing that can be said of many middle-born children is that they typically place great importance on their peer group. The middle child is well known for going outside the home to make friends faster than anybody else in the family. When a child feels like a fifth wheel at home, friends become very important; as a result, many middle children (but not all, of course) tend to be the social lions of the family. While firstborns, typically, have fewer friends, middle children often have many.
Middle children have a propensity to leave home first and live farther away from the family than anyone else. I observed a dramatic illustration of this tendency while I was a guest on Oprah Winfrey's show. The subject that day was sibling rivalry. Three charming young women, all sisters, were among the guests, and we quickly learned that the firstborn and the last born were residents of the Eastern state where they had grown up. They had settled down near their parents and other family members. But the middle child had moved to the West Coast.
I suppose she could have gotten another two thousand miles farther away by moving to Hawaii, but her point was still well made. Middle children are the ones who will most often physically distance themselves from the rest of the family. It's not necessarily because they're on the outs with everyone else. They simply like to do their own thing, make their own friends, and live their own lives.
All of this is not to say that middle children totally ignore their siblings or the rest of the family. One common characteristic of the middle child is that she is a good mediator or negotiator. She comes naturally into this role because she's often right in the middle, between big brother and little sister, whatever the case may be. And because she can't have Mom or Dad all to herself, she learns the fine art of compromise. Obviously, these skills are assets in adult life, and middle children often become the best adjusted adults in the family.
What is the main argument of this passage?

A. First-born children are the carders of the family banner and responsible for everything.
B. Middle-born children tend to be more independent and sociable while growing up.
C. Last-born children are the favorites who get most attention in the family.
D. Children are not really treated in the same way in the family.

Researchers have known that secondhand smoke can be just as dangerous for nonsmokers as smoking is for smokers, but now there's fresh evidence quantifying just how hazardous the after-burn from cigarettes can be, and how quickly it affects your body. Scientists at the Oregon Department of Health documented for the first time an hourly buildup of a cancer- causing compound from cigarette smoke in the blood of nonsmokers working in bars and restaurants in the state.
Reporting in the American Journal of Public Health, the researchers found that waitstaff and bartenders working a typical night shift gradually accumulated higher levels of NNK, a carcinogen in cigarette smoke, at the rate of 6% each hour they worked. NNK is known to be involved in inducing lung cancer in both lab rats and smokers.
"We were somewhat surprised by the immediacy of the effect and the fact that we could measure the average hourly increase," says Michael Stark, the lead author of the study and a principal investigator at the Mulmomah County Health Department in Oregon.
The authors are confident that the increases in NNK in the workers they tested most likely came from their exposure to smoke—the study included a control group of similar subjects in restaurants where no smoking was allowed. "There is experimental evidence from studies where you put nonsmokers in a room, blow smoke into the room and measure their artery function, that you see the platelets get sticky, which can cause clots and lead to a heart attack, and the ability of the arteries to dilate decreases very rapidly," says Dr. Matthew McKenna, director of the office on smoking and public health for the Centers for Disease Control.
All of which could mean more time loitering outside buildings and in alleyways for smokers intent on grabbing a puff. Thirteen states now prohibit smoking in restaurants altogether (most of these include bars as well), and while 11 states still put no restrictions on lighting up, individual cities within those states—such as Austin in Texas, for example have passed legislation banning smoking in eating establishments and other public areas.
It's just getting harder to refute the scientific evidence; in a study done in Scotland several months after that nation instituted a ban on smoking in public places, researchers found that following the ban, bar patrons showed stronger lung capacity and reduced levels of inflammation (a red flag for a number of chronic diseases, including heart disease and asthma). "We made it pretty clear that the science on this is pretty irrefutable," says McKenna. And if smokers have fewer places to smoke, that message may finally get heard.
According to the passage, the scientists carried out their researches on______.

A. smokers from different parts of the world
B. smokers from different states in the United States
C. actors and actresses who smoke a lot
D. waitstaff and bartenders
