passage below is followed by questions based on its content.Answer the questions on the basis of what is slated or impliedin each passage and in any introductory material that may be provided.Questions 6-7 are based on the following passage.The critic Edmund Wilson was not a self-consciousletter writer or one who tried to sustain studied mannerisms.Nor did he resort to artifice or entangle himself inLine circumlocutions.The young,middle-aged,and old Wilson5 speaks directly through his letters,which are informal forthe most part and which undisguisedly reflect his changingmoods.On occasion-in response,perhaps,to the miseryof a friend or a public outrage or a personal challengehecan become eloquent,even passionate,but that is not his10 prevailing tone.6.Based on

o(this page is iUegal.J JQuestions 10-18 are based on the following passage.The following passage was written by a physicist in J986.When astronomers point their telescopes io the nearestgalaxy,Andromeda,they see it as it was two million yearsago.That,s about the time Australopithecus*was baskingLine in the African sun.This little bit of time travel is possible5 because light takes two million years to make the trip fromthere to here.Too bad we couldnt turn things around andobserve Earth from some cozy planet in Andromeda.But looking at light from distant objects isnt real timetravel,the in-the-flesh participation in past and future found10 in literature.Ever since Ive been old enough to read sciencefiction.Ive dreamed of time traveling.The possibilitiesare staggering.You could take medicine back to fourteenth-century Europe and stop the spread of plague,or you couldtravel to the twenty-third century,where people take their15 annual holidays in space stations.Being a scientist myself,I know that time travel isquite unlikely according to the laws of physics.For onething,there would be a causality violation.If you couldtravel backward in time,you could alter a chain of events20 with the knowledge of how they would have turned out.Cause would no longer always precede effect.For example,you could prevent your parents from ever meeting.Contemplating the consequences of that will give you aheadache,and science fiction writers for decades have25 delighted in the paradoxes that can arise from travelingthrough time.Physicists are,of course,horrified at the thought ofcausality violation.Differential equations for the waythings should behave under a given set of forces and30 initial conditions would no longer be valid、since whathappens in one instant would not necessarily determinewhat happens in the next.Physicists do rely on a deterministic universe in which to operate,and time travel wouldalmost certainly put them and most other scientists35 permanently out of work.Stilk 1 dream of time travel.There is something verypersonal about time.When the first mechanical cluckswere invented,marking off time in crisp,regular intervals.it must have surprised people to discover that time40 flowed outside their own mental and physiological processes.Body time flows at its own variable rate,obliviousto the most precise clocks in the laboratory.In fact,thehuman body contains its own exquisite timepieces,all withtheir separate rhythms.There are the alpha waves in the45 brain;another clock is the heart.And all the while tick themysterious,ruthless clocks that regulate aging.Recently,I found my great-grandfathers favorite pipe.Papa Joe,as he was called,died more than seventy yearsago,long before I was bom.There are few surviving photo-50 graphs or other memorabilia of Papa J oe.But I do have hispipe,which had been tucked away in a drawer somewherefor years and was in good condition when I found it.I rana pipe cleaner through it.filled it with some tobacco I hadon hand,and settled down io read and smoke.After a cou-55 pie of minutes,the most wonderful and foreign blend ofsmells began wafting from the pipe.All the different occasions when Papa Joe had lit his pipe,all the different placeshe had been that I will never know-all had been lockedup in that pipe and now poured out into the room.1 was60
