Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph ismarked with a letter.

Are nursing homes as bad as people fear, or is that anout-modedstereotype（固定看法)? Can doing one’s homework really steer families to thebest places? It is genuinely hard to know.[C] I am about to make things more complicated by suggesting that what kind of facility an olderperson lives in may matter less than we have assumed. And that the characteristics adultchildren look for when they begin the search are not necessarily the things that make adifference to the people who are going to move in. I am not talking about the quality of care,let me hastily add. Nobody flourishes in a gloomy environment with irresponsible staff and apoor safety record. But an accumulating body of research indicates that some distinctionsbetween one type of elder care and another have little real bearing on how well residents do.[D] The most recent of these studies, published inThe journal of Applied Gerontology, surveyed150 Connecticut residents of assisted living, nursing homes and smaller residential carehomes（known in some states as board and care homes or adult care homes). Researchersfrom the University of Connecticut Health Center asked the residents a large number ofquestions about their quality of life, emotional well-being and social interaction, as well asabout the quality of the facilities.[E] “We thought we would see differences based on the housing types,” said the lead author of thestudy, Julie Robison, an associate professor of medicine at the university. A reasonableassumption—don’t families struggle to avoid nursing homes and suffer real guilt if theycan’t?[F] In the initial results, assisted living residents did paint the most positive picture. They wereless likely to report symptoms of depression than those in the other facilities, for instance,and less likely to be bored or lonely. They scored higher on social interaction.[G] But when the researchers plugged in a number of other variables, such differences disappeared.It is not the housing type, they found, that creates differences in residents’ responses. “It isthe characteristics of the specific environment they are in, combined with their own personalcharacteristics—how healthy they feel they are, their age and marital status,” Dr. Robisonexplained. Whether residents felt involved in the decision to move and how long they hadlived there also proved significant.[H] An elderly person who describes herself as in poor health, therefore, might be no lessdepressed in assisted living（even if her children preferred it) than in a nursing home. Aperson whohad input into where he would move and has had time to adapt to it might do aswell in a nursing home as in a small residential care home, other factors being equal. It is aninteraction between the person and the place, not the sort of place in itself, that leads to betteror worse experiences. “You can’t just say, ‘Let’s put this person in a residential care homeinstead of a nursing home—she will be much better off,’” Dr. Robison said. What matters,she added, “is a combination of what people bring in with them, and what they find there.”[I] Such findings, which run counter to common sense, have surfaced before. In a multi-state studyof assisted living, for instance, University of North Carolina researchers found that a host ofvariables—the facility’s type, size or age；whether a chain owned it；how attractive theneighborhood was—had no significant relationship to how the residents fared in terms ofillness, mental decline, hospitalizations or mortality. What mattered most was the residents’physical health and mental status. What people were like when they came in had greaterconsequence than what happened once they were there.[J] As I was considering all this, a press release from a respected research firm crossed my desk,announcing that the five-star rating system that Medicare developed in 2008 to help familiescompare nursing home quality also has little relationship to how satisfied its residents or theirfamily members are. As a matter of fact, consumers expressed higher satisfaction with theone-star facilities, the lowest rated, than with the five-star ones.（More on this study and thestar ratings will appear in a subsequent post.)[K] Before we collectively tear our hair out—how are we supposed to find our way in a landscapethis confusing?—here is a thought from Dr. Philip Sloane, ageriatrician（老年病学专家)atthe University of North Carolina:“In a way, that could be liberating for families.”[L] Of course, sons and daughters want to visit the facilities, talk to the administrators andresidents and other families, and do everything possible to fulfill their duties. But perhapsthey don’t have to turn themselves into private investigators or Congressional subcommittees.“Families can look a bit more for where the residents are going to be happy,” Dr. Sloane said.And involving the future resident in the process can be very important.[M] We all have our own ideas about what would bring our parents happiness. They have theirideas, too. A friend recently took her mother to visit an expensive assisted living/nursinghome near my town. I have seen this place—it is elegant, inside and out. But nobody greetedthe daughter and mother when they arrived, though the visit had been planned；nobodyintroduced them to the other residents. When they had lunch in the dining room, they satalone at a table.[N] The daughter feared her mother would be ignored there, and so she decided to move her into amore welcoming facility. Based on what is emerging from some of this research, that mighthave been as rational a way as any to reach a decision.
