4. What is paragraph 2 f the text mainly abut? A. The methds f estimatin. B. The underlying lgic f the effect. C. The causes f peple’s errrs. D. The design f Galtn’s experiment.
Para1: On March 7, 1907, the English statistician Francis Galtn published a paper which illustrated what has cme t be knwn as the "wisdm f crwds" effect. The experiment f estimatin he cnducted shwed that in sme cases, the average f a large number f independent estimates culd be quite accurate.Para2: This effect capitalizes n the fact that when peple make errrs, thse errrs aren't always the same. Sme peple will tend t verestimate, and sme t underestimate. When enugh f these errrs are averaged tgether, they cancel each ther ut, resulting in a mre accurate estimate. If peple are similar and tend t make the same errrs, then their errrs wn't cancel each ther ut. In mre technical terms, the wisdm f crwds requires that peple's estimates be independent. If fr whatever reasns, peple's errrs becme crrelated r dependent, the accuracy f the estimate will g dwn.

5. What did the fllw-up study fcus n? A. The size f the grups. B. The dminant members. C. The discussin prcess. D. The individual estimates.
Para3: But a new study led by Jaquin Navajas ffered an interesting twist (转折) n this classic phenmenn. The key finding f the study was that when crwds were further divided int smaller grups that were allwed t have a discussin, the averages frm these grups were mre accurate than thse frm an equal number f independent individuals. Fr instance, the average btained frm the estimates f fur discussin grups f five was significantly mre accurate than the average btained frm 20 independent individuals.Para4: In a fllw-up study with 100 university students, the researchers tried t get a better sense f what the grup members actually did in their discussin. Did they tend t g with thse mst cnfident abut their estimates? Did they fllw thse least willing t change their minds? This happened sme f the time, but it wasn't the dminant respnse. Mst frequently, the grups reprted that they "shared arguments and reasned tgether". Smehw, these arguments and reasning resulted in a glbal reductin in errr.
