The table summarizes the following list of 20 numbers: 1, 1, 1, 2, 2, 2, 2, 3, 3, 3, 5, 6, 7, 8, 8, 8, 9, 10, 10, 10. If a set of numbers is listed in increasing order, the median is the middle number (if the set contains an odd number of elements) or the average of the two middle terms (if the set contains an even number of elements). The median of a set of 20 numbers, therefore, is the average of the 10th and 11th terms. Since the 10th number is 3 and the 11th number is 5, the median is (3 + 5)/2 = 4.

The recent precipitous decline of print journalism as a viable profession has exacerbated long-held concerns about the state of investigative reporting in the United States.2. Facing lower print circulation and diminished advertising revenue, many major newspapers have reduced or eliminated investigative resources.3. Newspapers, the traditional nurturing ground for investigative journalism, have been hit especially hard by the widespread availability of free news online.4. To survive, investigative journalism must continue to adapt to the digital age. (1)It is not difficult to understand why a cash-strapped, understaffed publication might feel pressure to cut teams of investigative (2) reporter’s—their work is expensive and time-consuming. (3) Taking on the public interest, investigative journalism involves original, often long-form reporting on such topics as (4) illegal activities, street crime, corporate wrongdoing, and political corruption. An investigative story involves one or more experienced journalists dedicating their full energy and the resources of the publisher to a piece for a prolonged period of time. Expensive legal battles may ensue. The results of this work, though costly, havehelped keep those in power accountable. The exposure by Washington Post reporters Bob Woodward and Carl Bernstein of government misconduct in the Watergate scandal resulted in the resignation of President Richard Nixon in 1974. More recently, Seymour Hersh, reporting for the New Yorker in 2004, helped publicize the mistreatment of Iraqi prisoners by US personnel at Abu Ghraib during the Iraq War. (5) In these and other cases, exposure from reporters has served as an important (6) blockade to or scolding of malfeasance.While worrisome, the decline of traditional print media (7) could not entail the end of investigative journalism. (8) Although many newsrooms have reduced their staff, some still employ investigative reporters. Nonprofit (9) enterprises such as the Organized Crime and Corruption Reporting Project have begun to fill the void created by staff losses at newspapers and magazines. Enterprising freelance reporters, newly funded by nonprofits, make extensive use of social media,including blogs and Twitter, to foster a public conversation about key issues. The Help Me Investigate project, (10) for example, solicited readers to submit tips and information related to ongoing stories to its website. Far from marking the end of investigative journalism,(11) cooperation among journalists and ordinary citizens has been facilitated by the advent of the digital age through an increase in the number of potential investigators.Q.

Question based on the following passage and supplementary material.This passage is adapted from John Bohannon, "Why You Shouldnt Trust Internet Comments." ©2013 by American Association for the Advancement of Science.The “wisdom of crowds” has become a mantra ofthe Internet age. Need to choose a new vacuumcleaner? Check out the reviews on online merchantAmazon. But a new study suggests that such online(5) scores don’t always reveal the best choice. A massivecontrolled experiment of Web users finds that suchratings are highly susceptible to irrational “herdbehavior”—and that the herd can be manipulated.Sometimes the crowd really is wiser than you. The(10) classic examples are guessing the weight of a bull orthe number of gumballs in a jar. Your guess isprobably going to be far from the mark, whereas theaverage of many people’s choices is remarkably closeto the true number.(15) But what happens when the goal is to judgesomething less tangible, such as the quality or worthof a product? According to one theory, the wisdomof the crowd still holds—measuring the aggregate ofpeople’s opinions produces a stable, reliable(20) value. Skeptics, however, argue that people’sopinions are easily swayed by those of others. Sonudging a crowd early on by presenting contraryopinions—for example, exposing them to some verygood or very bad attitudes—will steer the crowd in a(25) different direction. To test which hypothesis is true,you would need to manipulate huge numbers ofpeople, exposing them to false information anddetermining how it affects their opinions.A team led by Sinan Aral, a network scientist at(30) the Massachusetts Institute of Technology inCambridge, did exactly that. Aral has been secretlyworking with a popular website that aggregates newsstories. The website allows users to make commentsabout news stories and vote each other’s comments(35) up or down. The vote tallies are visible as a numbernext to each comment, and the position of thecomments is chronological. (Stories on the site get anaverage of about ten comments and about three votesper comment.) It’s a follow-up to his experiment(40) using people’s ratings of movies to measure howmuch individual people influence each other online(answer: a lot). This time, he wanted to know howmuch the crowd influences the individual, andwhether it can be controlled from outside.(45) For five months, every comment submitted by auser randomly received an “up” vote (positiv e); a“down” vote (negative); or as a control, no vote at all.The team then observed how users rated thosecomments. The users generated more than(50) 100,000 comments that were viewed more than10 million times and rated more than 300,000 timesby other users.At least when it comes to comments on newssites, the crowd is more herdlike than wise.(55) Comments that received fake positive votes from theresearchers were 32% more likely to receive morepositive votes compared with a control, the teamreports. And those comments were no more likelythan the control to be down-voted by the next viewer(60) to see them. By the end of the study, positivelymanipulated comments got an overall boost of about25%. However, the same did not hold true for negativemanipulation. The ratings of comments thatgot a fake down vote were usually negated by an up(65) vote by the next user to see them.“Our experiment does not reveal the psychologybehind people’s decisions,” Aral says, “but anintuitive explanation is that people are moreskeptical of negative social influence. They’re more(70) willing to go along with positive opinions from otherpeople.”Duncan Watts, a network scientist at MicrosoftResearch in New York City, agrees with thatconclusion. “[But] one question is whether the(75) positive [herding] bias is specific to this site” or truein general, Watts says. He points out that thecategory of the news items in the experiment had astrong effect on how much people could bemanipulated. “I would have thought that ‘business’ is(80) pretty similar to ‘economics,’ yet they find a muchstronger effect (almost 50% stronger) for the formerthan the latter. What explains this difference? If we’regoing to apply these findings in the real world, we’llneed to know the answers.”(85) Will companies be able to boost their products bymanipulating online ratings on a massive scale?“That is easier said than done,” Watts says. If peopledetect—or learn—that comments on a website arebeing manipulated, the herd may spook and leave(90) entirely.Mean score: mean of scores for the comments in each category, with the score for each comment being determined by the number of positive votes from website users minus the number of negative votesAdapted from Lev Muchnik, Sinan Aral, and Sean J. Taylor, “Social Influence Bias: A Randomized Experiment.” ©2013 by American Association for the Advancement of Science.Q.Over the course of the passage, the main focus shifts from a discussion of an experiment and its results to

Adapted from Common Diseases of Farm Animals by R. A. Craig (1916, 2nd ed.)The common bot-fly of the horse (G. equi) has a heavy, hairy body. Its color is brown, with dark and yellowish spots. The female fly can be seen during the warm weather, hovering around the horse, and darting toward the animal for the purpose of depositing the egg. The color of the egg is yellow, and it adheres firmly to the hair. It hatches in from two to four weeks, and the larva reaches the mouth through the animal licking the part. From the mouth, it passes to the stomach, where it attaches itself to the gastric mucous membrane. Here it remains until fully developed, when it becomes detached and is passed out with the feces. The third stage is passed in the ground. This takes place in the spring and early summer and lasts for several weeks, when it finally emerges a mature fly.The bot-fly of the ox (H. lineat

Question based on the following passage.This passage is adapted from Joshua Foer, Moonwalking with Einstein: The Art and Science of Remembering Everything. ©2011 by Joshua Foer.In 2000, a neuroscientist at University CollegeLondon named Eleanor Maguire wanted to find outwhat effect, if any, all that driving around thelabyrinthine streets of London might have on(5)cabbies’ brains. When she brought sixteen taxidrivers into her lab and examined their brains in anMRI scanner, she found one surprising andimportant difference. The right posteriorhippocampus, a part of the brain known to be(10)involved in spatial navigation, was 7 percent largerthan normal in the cabbies—a small but verysignificant difference. Maguire concludedthat all of that way-finding around London had physicallyaltered the gross structure oftheir brains. The more(15)years a cabbie had been on the road, the morepronounced the effect.The brain is a mutable organ, capable—withinlimits—of reorganizing itself and readapting to newkinds of sensory input, a phenomenon known as(20)neuroplasticity. It had long been thought that theadult brain was incapable ofspawning newneurons—that while learning caused synapses torearrange themselves and new links between braincells to form, the brain’s basic anatomical structure(25)was more or less static. Maguire’s study suggested theold inherited wisdom was simply not true.After her groundbreaking study of Londoncabbies, Maguire decided to turn her attention tomental athletes. She teamed up with Elizabeth(30)Valentine and John Wilding, authors of the academicmonograph Superior Memory, to study tenindividuals who had finished near the top of theWorld Memory Championship. They wanted to findout if the memorizers’ brains were—like the London(35)cabbies’—structurally different from the rest of ours,or if they were somehow just making better use ofmemory abilities that we all possess.The researchers put both the mental athletes and agroup of matched control subjects into MRI scanners(40)and asked them to memorize three-digit numbers,black-and-white photographs of people’s faces, andmagnified images of snowflakes, while their brainswere being scanned. Maguire and her team thought itwas possible that they might discover anatomical(45)differences in the brains of the memory champs,evidence that their brains had somehow reorganizedthemselves in the process of doing all that intensiveremembering. But when the researchers reviewed theimaging data, not a single significant structural(50)difference turned up. The brains of the mentalathletes appeared to be indistinguishable from thoseof the control subjects. What’s more, on every singletest of general cognitive ability, the mental athletes’scores came back well within the normal range. The(55)memory champs weren’t smarter, and they didn’thave special brains.But there was one telling difference between thebrains of the mental athletes and the control subjects:When the researchers looked at which parts of the(60)brain were lighting up when the mental athletes werememorizing, they found that they were activatingentirely different circuitry. According to thefunctional MRIs [fMRIs], regions of the brain thatwere less active in the control subjects seemed to be(65)working in overdrive for the mental athletes.Surprisingly, when the mental athletes werelearning new information, they were engagingseveral regions of the brain known to be involved intwo specific tasks: visual memory and spatial(70)navigation, including the same right posteriorhippocampal region that the London cabbies hadenlarged with all their daily way-finding. At firstglance, this wouldn’t seem to make any sense.Why would mental athletes be conjuring images in(75)their mind’s eye when they were trying to learnthree-digit numbers? Why should they be navigatinglike London cabbies when they’re supposed to beremembering the shapes of snowflakes?Maguire and her team asked the mental athletes(80)to describe exactly what was going through theirminds as they memorized. The mental athletes saidthey were consciously converting the informationthey were being asked to memorize into images, anddistributing those images along familiar spatial(85)journeys. They weren’t doing this automatically, orbecause it was an inborn talent they’d nurtured sincechildhood. Rather, the unexpected patterns of neuralactivity that Maguire’s fMRIs turned up were theresult of training and practice.Q.The main purpose of the fifth paragraph (lines 57-65) is to
