In addition to conventional galaxies, the universe
contains very dim galaxies that until recently went
unnoticed by astronomers. Possibly as numerous
as conventional galaxies, these galaxies have the
same general shape and even the same
approximate number of stars as a common type of
conventional galaxy, the spiral, but tend to be much
larger. Because these galaxies' mass is spread out
over larger areas, they have far fewer stars per unit
volume than do conventional galaxies. Apparently
these low-surface-brightness galaxies, as they are
called, take much longer than conventional galaxies
to condense their primordial gas and convert it to
stars-that is, they evolve much more slowly.
These galaxies may constitute an answer to the
long-standing puzzle of the missing baryonic mass
in the universe. Baryons-subatomic particles that
are generally protons or neutrons-are the source .
of stellar, and therefore galactic, luminosity, and so
their numbers can be estimated based on how
luminous galaxies are. However, the amount of
helium in the universe, as measured by
spectroscopy, suggests that there are far more
baryons in the universe than estimates based on
galactic luminosity indicate. Astronomers have long
speculated that the missing baryonic mass might
eventually be discovered in intergalactic space or as
some large population of galaxies that are
difficult to detect.

PhishCo runs a number of farms in the arid province of Nufa, depending largely on irrigation. Now, as part of a plan to efficiently increase the farms' total production, it plans to drill down to an aquifer containing warm, slightly salty water that will be used to raise fish in ponds. The water from the ponds will later be used to supplement piped-in irrigation water for PhishCo's vegetable fields, and the ponds and accompanying vegetation should help reduce the heat in the area of the farms.
Which of the following would, if true, most strongly suggest that the plan, if implemented, would increase the overall efficiency of PhishCo's farms?

Human beings, born with a drive to explore and experiment, thrive on learning. Unfortunately, corporations are oriented predominantly toward controlling employees, not fostering their learning. Ironically, this orientation creates the very conditions that predestine employees to mediocre performances. Over time, superior performance requires superior learning, because long-term corporate survival depends on continually exploring new business and organizational opportunities that can create new sources of growth. To survive in the future, corporations must become "learning organizations," enterprises that are constantly able to adapt and expand their capabilities. To accomplish this, corporations must change how they view employees. The traditional view that a single charismatic leader should set the corporation's direction and make key decisions is rooted in an individualistic worldview. In an increasingly interdependent world, such a view is no longer viable. In learning organizations, thinking and acting are integrated at all job levels. Corporate leadership is shared, and leaders become designers, teachers, and stewards, roles requiring new skills: the ability to build shared vision, to reveal and challenge prevailing mental models, and to foster broader, more integrated patterns of thinking. In short, leaders in learning organizations are responsible for building organizations in which employees are continually learning new skills and expanding their capabilities to shape their future.
