Read the following article and select the best answer. Article: Celebrities are more in love with themselves than the average person,according to a new study. In case anyone needed proof, a new study supports the widely held perception:Famous people are more narcissistic ,which means they are more in love with themselves than the average person is.That is the conclusion drawn by Drew Pinsky and S.Mark Young of the University of Southern California,whose study of 200 celebrities will appear in the Journal Of Research in Personality. It is not the entertainment industry that turns stars into narcissists,the study found.Rather, it suggests,the self-adoring people seek jobs in show business.The study, whose subjects were a11 celebrities from Pinsky's'Loveline'radio show, found that reality TV stars were the most narcissistic of all celebrities.Female stars were also more likely than the male stars to exhibit narcissistic characteristics. It's "common sense" that celebrities are narcissists,said Jeremy Ritzlin,a longtime Hollywood psychologist who has not seen the study."Everyone knows famous people are really in love with themselves,"he said."So it would be natural for narcissists to be attracted toward the stage and spotlight,where other people will also think highly of them." Pinsky, an assistant clinical professor of psychiatry at USC'S Keck School of Medicine,said narcissists desire attention,are overconfident,behave strangely and lack sympathy."However, they are easily-liked,especially on first meeting,are outgoing and perform well in public," added Pinsky, who has hosted the radio show"Loveline"for 20 years. Celebrity guests appearing on the program were randomly chosen to participate in the study.They anonymously took the Narcissistic Personality Inventory test.which rates self-love levels based on seven components:superiority, exhibitionism,entitlement,vanity,authority, exploitativeness,and self-sufficiency. Question: How were the celebrities surveyed in the study? - They were interviewed by Drew Pinsky and S.Mark Young. - They were invited to the University of Southern California. - They appeared on Pinsky's'Loveline'radio show. - They took the Narcissistic Personality Inventory test.
They took the Narcissistic Personality Inventory test.

Read the following article and select the best answer. Article: If, for some reason, you had 2,010 empty plastic bottles, what would you do? You'd probably sell them cheaply, right? But Xia Yu collected 2,010bottles and built a boat with them, As you read this, Xia is, in fact, on a river somewhere in Anhuai, slowly going towards his destination: the Expo Garden in Shanghai.2,010 plastic bottles was to celebrate Expo 2010 Shanghai.On the opening day of the Expo, Xia, together with five friends, went on a 1,500 - km journey from Xiangtan to the Expo Garden, in spite of the doubt whether they'll make it.After all, the boat they are on can hardly be called a boat.It cost only 2,000 yuan to build in a month. What's keeping Xia going is a major cause behind the trip."We are examining water pollution through our journey and trying to promote a low - carbon lifestyle.Before we started, no one believed we could sail the boat to the Dongting Lake.But we made it." But as they expected, the journey has not always been smooth.Of the six from Xiangtan, four gave up.As of the press time , only Xia and his friend Huang Ying were on the boat.Huang suffered from a disease when they reached Jiujiang, Jiangxi province, Xia said, "There are so many things that can stop up from making it to Shanghai, like the weather, health, and sometimes swift rive water." "The boat was produced in a factory according to our design, and perhaps it's not in a very good condition.But," Xia said, "we are wearing life jackets"."Some boats passing by offered help." What is more of a reward for Xia and Huang is that the Yangtze Rive truned out much cleaner than they had expected.Although Xia and Huang are uncertain about the journedy ahead, they are "quite happy" with what they have already achieved."After all, it's not the destination that counts.It's always the course that matters the most." Question: Xia Yu doubts the success of the journey because of _ . - such a 1ong journey on the river - the poor boat and the bad weather - few people taking part in the journey - the seriously polluted river in some parts
(Answer)
the poor boat and the bad weather

Ques: Read the following article and select the best answer. Article: Mars appears to be flowing with small streams of salty water,at least in the summer,scientists reported Monday."It suggests that.it would be possible for there to be life today on Mars,"NASA's science mission chief,John Grunsfeld,said at a news conference on September 28,2015. The streams are about 12 to 15 feet wide and 300 feet or more long,scientists said."What we're dealing with is wet soil.thin layers of wet soil,not standing water,"said Aifred McEwen of the University of Arizona at Tueson!the principal scientist for the Mars Reconnaissance Orbiter's high-resolution imaging experiment. Because liquid water is essential to life,the findings could have major implications for the possibility of Martian life.The researchers said further exploration is needed to determine whether microscopic life exists on the planet. The presence of liquid water could also make life easier for astronauts visiting or living on Mars.Water could be used for drinking and for creating oxygen and rocket fuel.NASA's goal is to send humans there in the 2030s. The evidence of flowing water consists largely of dark,narrow streaks on the surface that tend to appear and grow during the warmest Martian months and fade the rest of the year. Mars is extremely cold even in summer,and the streaks are in places where the temperature is as low as minus 10 degrees Fahrenheit.But salt can lower the freezing point of water and melt ice. The source of the water is a mystery.Scientists noted it could be melting ice.It could be an underground aquifer,which is rock or sand that can hold water.It is possibly water vapor from the thin Martian atmosphere,Or it may be a combination Michael Meyer,lead scientist for NASA's Mars exploration program,said the only definitive way for now to determine whether there's life on Mars is to collect rocks and soil for analysis on Earth - something a U.S.lander set for lift-off in 2020 will do. Question: According to John Grunsfeld,there seems to be _ on Mars. - salty water - standing water - rocket fuel - human beings
Ans:
salty water
