　　In the 1980&aposs,astronomer BohdanPaczynski proposed a way of determining whether the enormousdark haloconstituting the outermost part of the Milky Way galaxy is composed ofMACHO&aposs(massive compact halo objects), which are astronomical objects too dimto bevisible. Paczynski reasoned thatifMACHO&aposs make up this halo, a MACHO would occasionally drift in front of astarin the Large Magellanic Cloud, a bright galaxy near the Milky Way. The gravity of a MACHO that had sodrifted,astronomers agree, would cause the star&aposs light rays, which wouldotherwisediverge, to bend together so that, as observed from Earth, the starwouldtemporarily appear to brighten, a process known as microlensing. Because many individual stars areofintrinsically variable brightness, some astronomers have contended that thebrighteningof intrinsically variable stars can be mistaken formicrolensing. However, whereas thedifferent colors oflight emitted by an intrinsically variable star are affecteddifferently whenthe star brightens, all of a star&aposs colors are equally affectedbymicrolensing. Thus, if a MACHOmagnifiesa star&aposs red light tenfold, it will do the same to the star&aposs bluelight andyellow light. Moreover, it ishighlyunlikely that a star in the Large Magellanic Cloud will undergomicrolensingmore than once, because the chance that a second MACHO would passin front ofexactly the same star is minuscule.

　　It can be inferredfrom the passagethat which of the following would constitute the strongestevidence of themicrolensing of a star in the Large Magellanic Cloud? 选D

　　(A) The brightnessof such a staris observed to vary at irregular intervals.

　　(B) The brighteningof such a staris observed to be of shorter duration than the brightening ofneighboringstars.

　　(C) The red lightof such a star isobserved to be brighter than its yellow light and its bluelight.

　　(D) Thered light, yellow light,and blue light of such a star are observed to bemagnified temporarily by thesame factor.

　　(E) The red lightof such a star isobserved to have increased tenfold.

　　Question #56. 639-04 (23927-!-item-!-188;#058&000639-04)

　　According to thepassage,Paczynski&aposs theory presumes that if MACHO&aposs constituted the Milky Way&apossdarkhalo, occasionally a MACHO would 选B
