following passage.Searching for Guinevere Stories of kings and queens have captivated readers for centuries,and arguably,the tales of King Arthur and Guinevere are among the most enchanting.Arthur ruled the kingdom of Camelot,and Guinevere was his queen.But were they real people or fictional characters?The debate has continued for centuries.Though many scholars have found evidence that the legendary Arthur was,at the very least,based on a real person who lived in Britain roughly between 450 and 1 500 CE.They continue to search for the historical identity of Guinevere.Guinevere first appeared as King Arthurs queen in one of the most widely-studied works of Arthurian literature,2 The History of the Kings of Britain.This book was written by Geoffrey of Monmouth around 1135 CE.Geoffreys historical treatment of the legend is often 3 sited as evidence that the queen of Camelot existed,as the book chronicles the lives of a number of historical rulers.Which choice most effectively combines the sentences at the underlined portion?A)The History of the Kings of Britain,and this bookB)The History of the Kings of Britain,whichC)a book called The History of the Kings of Britain,asthisD)a book called The History of the Kings of Britain,and thisA)NO CHANGEB)insightedC)citedD)incited23222Guinevere is identified by Geoffrey as a noblewoman of Roman descent who met King Arthur in the court of Duke Cador of Cornwall,where she lived as a ward.In this version,Guinevere possesses little if any agency of her own.4 In this second version,Guinevere is an active participant in court politics;her partnership with Arthur is characterized by mutual respect,and he accepts her advice on important issues.As many Arthurian scholars know,the distinction between history and literature was blurred in the Middle Ages.Consequently,the true identity of Guinevere may never be known with certainty.Yet regardless of whether Guinevere was real or fictional,her story 5 had endured for centuriesand through each retelling,she continues to live on in the imaginations of people around the world.Which choice most effectively sets up the portrayal of Guinevere discussed in the rest of the paragraph?A)However,Chrtien de Troyes,a French poetand contemporary of Geoffrey,painted a verydifferent version of the queen.B)Chrtien de Troyes was a French poet who livedin the same century;he wrote many beautiful andmoving poems that involve the knights of KingArthur.C)Many historians believe that the French poetChrtien de Troyes was the original writer tointroduce Lancelots character into the romanceof Arthur and Guinevere.D)In his poem Eric and Enide,the French poetChrtien de Troyes depicts the romance oftwo lesser known characters in the Arthuriantradition.A)NO CHANGEB)was enduringC)would have enduredD)has endured45322A)NO CHANGEB)comets,the distribution of organic compounds inour solar system,C)comets,the distribution of organic compounds inour solar system;D)comets;the distribution of organic compounds inour solar system,3At this point,the writer wants to add accurate information from the graph.Which choice best accomplishes this goal?A)From 1978 to 2014,the number of successfulmissions increased from 28 percent to 72 percent.B)Before 2014,the majority of attempted cometarymissions were considered unsuccessful.C)Between then and 2014,72 percent of thecometary missions were successful.D)Of the missions attempted since then,44 percenthave been successful.1Questions 1-5 are based on the following passage.Cometary Missions:Trajectory for Success Scientists have been launching cometary missions since 1978.The first one,a joint mission by the European Space Agency and the National Aeronautics and Space Administration(NASA),was a“flyby”in which the spacecraft collected data while passing around Comet Giacobini-Zinner.1 The landing of the Rosetta space probe on comet 67P/Churyumov-Gerasimenko in 2014 marked the first time that a probe landed directly on a 2 comet and giving scientists an unprecedented opportunity to study the surface of a comet.In order to continue this valuable research,additional missions are needed;thus,it is critical that more funding be allocated for this purpose.The 2014 Rosetta mission provided a rare opportunity for scientists to test a number of hypotheses regarding the composition of 3 comets;the distribution of organic compounds in our solar system and the origins of life on Earth.Unlike other cometary missions,the Rosetta spacecraft contained a probe,Philae,that was able to land on the surface of a comet.Based on data collected from Philae,scientists were able to conclude that the water vaporA)NO CHANGEB)comet,but it gaveC)comet,yet givesD)comet,giving2224on the comet was substantially different than the water vapor on Earth,suggesting that the water on Earth likely did not originate from comets.In addition,scientists have used the data from Philae 4 to investigate why essential amino acids on Earth exist almost exclusively in one of two possible forms.Claudia Alexander,a project scientist for Rosetta at NASAs Jet Propulsion Laboratory,says that the data collected from 67P will give us a fuller understanding of how substances form to create livable environments.In addition to improving our understanding of life on Earth,an increase in funds for cometary missions would give scientists an opportunity to learn from 5 theyre failures and improve future missions.During the Rosetta mission,for example,the probe bounced and did not fully insert itself into the comet.Luckily,the landing did succeed,but more opportunities for trials would help scientists perfect their methods and aid in the collection of data from different types of comets in our solar system.A)NO CHANGEB)to investigate,whyC)to:investigate whyD)to investigate why:A)NO CHANGEB)theirC)itsD)its45Percentage of Successful Cometary Missions(1978-2014)Source:NASA Current and Past

for a difficult surgery by“operating”on a full-sized,electronically responsive model of a patient.It may seem fantastical,but one engineer is working to make this scenario possible.Dr.Toshio Fukuda is a pioneer in the field of medical robotics.In designing his medical robotic equipment,Dr.Fukuda draws upon a variety of disciplines and skill sets.His work serves as an example of how collaboration across a variety of fields can drive innovation.1 Dr.Fukudas career is a case study in how theinteraction of vastly different fields can produce exciting results.2 He did not begin his career with the goal of developing medical robotics.3 Rather,Dr.Fukuda earned his Ph.D.in mechanical 2 engineeringnot medicine;and his early work focused on finding new ways for robots to move.4 Together,they designed a micro-robot that could be used for clearing blocked arteries and performing other delicate operations.5 Shortly thereafter,Dr.Fukuda was approached by a doctor who asked if he could build a robot that could travel inside a humans blood vessels.3 A)NO CHANGEB)engineeringnot medicine,C)engineering not medicineD)engineeringnot medicineTo make this paragraph most logical,sentence 4 should be placedA)where it is now.B)before sentence 1.C)after sentence 2.D)after sentence 5.23226 Today,Dr.Fukuda has moved from the world of the micro-robot to 4 the macro-robot.He is busy developing full-sized medical models of patients scheduled to undergo complex surgical procedures.These types of surgeries are rarely performed by a single doctor.Rather,a team of specialists works together in close coordination to complete an operation.Dr.Fukudas robots help these teams to train for surgery by giving them the opportunity to rehearse an entire surgical procedure on a full-scale robotic replica of the patient.Working together,5 innovators in robotics and medicine share their expertise to save lives.According to Fukuda,“medical robotics is a very interdisciplinary area.”It draws upon the expertise of surgeons,medical researchers,robotics engineers,and even computer programmers.A)NO CHANGEB)that of the macro-robot.C)those of the macro-robot.D)macro-robots.A)NO CHANGEB)the expertise of innovators in robotics andmedicine is shared to save lives.C)lives are saved by innovators in robotics andmedicine sharing their expertise.D)the sharing of expertise by innovators in roboticsand medicine saves lives.45722A)NO CHANGEB)the purpose of eating.C)when one ate.D)eating1Questions 1-5 are based on the following passage.The Complex History of the Simple Chopstick The origin of chopsticks reaches back to the Shang Dynasty of ancient China.At that time,chopstickswhich were then called“Zhu”were used for cooking rather than 1 to eat.Because the people of ancient China liked to steam or boil their food,chopsticks were originally used to reach deep into boiling pots of water or oil.However,according to Chinese lore,chopsticks later evolved into an eating utensil during the Han Dynasty due to the influence of the Chinese philosopher,Confucius.Both a pacifist and vegetarian,Confucius believed that knives and other sharp utensils were inappropriate for mealtime because they reminded people of violence and warfare.Chopsticks,on the other hand,allowed people to savor their meals in a more relaxed and enjoyable setting.2 At this point,the writer wants to add a sentence that will provide an effective transition from the first paragraph to the second.Which choice best accomplishes this goal?A)Regardless of whether or not the nod toConfucius is accurate,chopsticks becameubiquitous throughout China and much of Asiaafter his death.B)Confucius is also famous for championing thedoctrine,based on his philosophical teachings,“Do not do to others what you do not want doneto yourself.”C)Ironically,though,Confucius did support anumber of rebellions.D)It was during this period that people beganholding chopsticks in their dominant hand andhandling them using their thumb,middle,andring fingers.2228 Since then,the diversity of chopstick styles and uses 3 has quickly expanded.In China,for example,chopsticks are often longer and taper to a blunt end,while in Japan,chopsticks are shorter and taper to a sharp end.In addition to the length of chopsticks,the materials used to make them also vary considerably between cultures.4 In Korea,it is also customary to use spoons for rice and chopsticks for larger,more manageable pieces of food.As different chopstick styles have evolved over centuries,so have a number of cultural traditions and taboos.In China,for example,it is customary to transfer food between relatives as a sign of caring and respect.In Japan,on the other hand,using chopsticks to transfer food and other materials is considered taboo and is reserved solely for funeral rites.Given 5 their importance and prominence in Asian history,chopsticks have become as unique and nuanced as the cultures from which they arose.A)NO CHANGEB)haveC)have beenD)wereWhich choice provides an example that most effectively supports the claim made in the previous sentence?A)In both China and Japan,chopsticks are oftenmade out of wood or bamboo.B)Unlike the chopsticks found in traditional homes,the chopsticks found in Chinese restaurants areoften made out of melamine plastic.C)While chopsticks in China are often made ofwood,those from Korea are often made of metalssuch as brass or silver.D)The material from which chopsticks are made,such as jade,ivory,or porcelain,can also signalones social status.A)NO CHANGEB)their prominence inC)the high historical importance of chopstickswithinD)how important chopsticks prominence is withinthe past of3459221A)NO CHANGEB)their fine robes and jewelry indicatingC)while their fine robes and jewelry indicateD)meaning their fine robes and jewelry indicate2Which choice provides the best transition between the first and second paragraphs?A)This striking and morbid secret image isan example of a painting technique calledanamorphosis.B)Unbeknownst to most viewers,the skullrepresents the ultimate fate and mortality of allmen.C)However,a century earlier,Leonardo da Vincibegan experimenting with perspective in a similarmanner.D)Figures such as this one can be constructed usinga mirror to transform flat,two-dimensionalimages into distorted,three-dimensional ones.3Questions 1-5 are based on the following passage.The Ambassadors:A Meditation on Mortality The Ambassadors,a
