存在看不见的物质。选项A"Thatthegravitationaleffectsobservedingalaxyclustersweregreaterthanthoseexplainedbyvisiblematter"最准确地概括了他的观察和推断的基础。9.定位：第一段"Observationsshowthattheouterstarsandgasingalaxiesrotatemuchfasterthancanbeexplainedbythegravitationalpullofthevisiblematter.Tomaintainthesehighvelocitieswithoutflyingapart,astronomersconcludethattheremustbeasignificantamountofunseenmassexertingagravitationalforce."外围天体旋转速度快，需要额外的引力（来自暗物质）来束缚它们。选项B"Thatthehighrotationalvelocitiesofstarsandgasingalaxies'outerregionsrequireadditional,unseengravitationalforce"概括了这一点。10.定位：第二段"Darkmatterdoesnotemit,absorb,orreflectlight,makingitinvisibleandundetectablebyconventionalmeans."暗物质不发光、不吸光、不反光，因此无法通过常规方法（如光学望远镜）探测到。选项C"Itslackofinteractionwithelectromagneticradiation,makingitinvisible"指出了核心原因，即不与电磁波相互作用。11.定位：最后一段"Thesearchfordarkmattercontinuestobeamajorfocusofobservationalandexperimentalphysics,drivenbythedesiretouncoveroneofthemostelusivecomponentsofouruniverse...""Elusive"在这里指难以找到、难以理解的。选项C"Hardtofindorunderstand"是最接近的意思。12.定位：第一段"...darkmatterplaysacrucialroleintheformationandstabilityofgalaxyclusters,whicharethelargeststructuresintheuniverseheldtogetherbygravity.Withouttheadditionalgravitationalbindingprovidedbydarkmatter,theseclusterswouldnotformorremainintact."暗物质对于星系团的形成和稳定至关重要，提供了额外的引力束缚。选项A"Itsroleinprovidingthenecessarygravitationalforcetoformandholdtogetherlarge-scalestructureslikegalaxyclusters"概括了其在宇宙大尺度结构中的作用。13.定位：第一段"neuroscientistshavereliedheavilyonanima
