Passage 2　　(1) A one-month survey results indicate that smoking, alcohol and marijuana use increase among residents of Manhattan during the five to eight weeks after the terrorist attacks on the World Trade Center which took place on September 11, 2001. Almost one-third of the nearly 1000 persons interviewed reported an increased use of alcohol, marijuana, or cigarettes following the September 11 attacks. About one-fourth of the respondents said they were drinking more alcohol in the weeks after September 11; about one tenth reported an increase in smoking, and 3.2% said they had increased their use of marijuana.　　(2) The investigators found survey participants by randomly dialing New York City phone numbers and screened potential respondents for Manhattan residents living in areas close to the World Trade Center. Interviews were conducted with 988 individuals between October 16 and November 15, 2001. Participants were asked about their cigarette smoking, alcohol drinking, and marijuana use habits before and after September 11. During the week prior to September 11, 2001, 22.6% of the participants reported smoking cigarettes, 59.1% drinking alcohol, and 4.4% using marijuana. After September 11, 23.4% reported smoking cigarettes, 4.4% drinking alcohol, and 5.7% smoking marijuana. Among those who smoked, almost 10% reported smoking at least an extra pack of cigarettes a week and among those who drank alcohol, more than 20% reported imbibing at least one extra drink a day.　　The researchers found that people who reported an increase in substance abuse were more likely to suffer from post-traumatic stress disorder (PTSD) and from depression (3) people who reported an increase in cigarette smoking or marijuana use were also more likely to have both PTSD and depression, while those people who reported an increase in alcohol use were more likely to have depression only. (4) Persons who were living closer to the World Trade Center were more likely to increase their cigarette smoking, but other factors such as being displaced from one’s home, losing possessions during the attacks, or being involved in the rescue efforts were not consistently associated with increased substance use. Symptoms of panic attack were associated with an increase in the use of all substances.　　Increase in substance abuse did not differ significantly between men and women or among racial or ethnic groups. (5) Demographic factors such as age, marital status, and income seemed tip play a more critical role in determining if the events of September 11 led to an increase in substance use.

Statistics issued in New Jersey suggested that ______.

Which of the following about the New Jersey study is TRUE?

A set of golden lights hovering silently in the night sky in a “V” formation stopped traffic on the New Jersey Turnpike, but were the drivers seeing visitors from outer space or just a set of military flares flaming out?At least 15 people contacted police to report seeing strange lights in the New Jersey sky over the weekend. More than a dozen people, including two Carteret, N.J., police officers, saw the lights last weekend, and several of the witnesses described a sense of serenity that seemed to emanate from the celestial display. The gold lights hovered for awhile, according to the witnesses, and then disappeared.To some, the description sounded very much like the so-called Phoenix Lights, another V formation that appeared in the sky near Phoenix in March 1997. Like the apparition in New Jersey, the Phoenix lights were caught on videotape. The formation also matches reports of unexplained lights in the sky from all across the United States, as well as England and Europe.
