　　The primary purpose of the passage is to

　　A. describe a phenomenon and consider its scientific significance

　　B. contrast two phenomena and discuss a puzzling difference between them

　　C. identify a newly discovered phenomenon and explain its origins

　　D. compare two classes of objects and discuss the physical properties of each

　　E. discuss a discovery and point out its inconsistency with existing theory

　　--------------------------------------------------------------------------------

　　GWD-4-Q36:

　　The author mentions the fact that baryons are the source of stars’ luminosity primarily in order to explain

　　A. how astronomers determine that some galaxies contain fewer stars per unit volume than do others

　　B. how astronomers are able to calculate the total luminosity of a galaxy

　　C. why astronomers can use galactic luminosity to estimate baryonic mass

　　Baryons—subatomic particles that are generally protons or neutrons—are the source of stellar, and therore galactic, luminosity, and so their numbers can be estimated based on how luminous galaxies are.

　　D. why astronomers’ estimates of baryonic mass based on galactic luminosity are more reliable than those based on spectroscopic studies of helium

　　E. how astronomers know bright galaxies contain more baryons than do dim galaxies

　　GWD-4-Q37:

　　It can be inferred from the passage that which of the following is an accurate physical description of typical low-surface-brightness galaxies?

　　A. They are large spiral galaxies containing fewer stars than do conventional galaxies.

　　B. They are compact but very dim spiral galaxies.

　　C. They are diffuse spiral galaxies that occupy a large volume of space.

　　the spiral, but tend to be much larger.

　　Because these galaxies’ mass is spread out over larger areas,

　　D. They are small, young spiral galaxies that contain a high proportion of primordial gas.

　　E. They are large, dense spirals with low luminosity.
