One important outcome of the work on the expression of genes in developing embryos is sure to
be knowledge that can help preventing birth defects. Just as promising (26)


is the possibility of unraveling the complicated writing (27)


of the brain. A mechanic gets valuable insight how an (28)


automobile
works
by
rebuilding
car
engines;
similarly,
neuroscientists
can
learn
how
the
brain functions from (29)


the way it is put together. The next step pursuing the (30)


goal is to find out how the blueprint genes, the home box genes, control the expression of
other
genes
that
create
the
valves
and
piston
of
the
working
cerebral
engine.
The
protein
encoded by the latter genes could change the (31)


stickiness
of
the
cell
surface,
the
shape
of
the
cell
or
its
metabolism
to
create
the
characteristic peculiar to, say, neurons or neural-crest cell. Surface proteins may be the (32)


mechanism,
whereby
similar
programmed
cells
stick
together
to
form
specific
structures;
they might also sense (33)


the local environment to help the cell decide what is to do. Clarifying those mechanisms will
engage the best talents in (34)


embryology and molecular biology for some times to come. (35)


What is perhaps the most intriguing question of all is if the brain is powerful enough to solve
the puzzle of its own creation.

Vitamins, like minerals, are chemicals. There is absolutely not difference in the chemical structure
(26)


of the nature vitamin C and the chemical structure (27)


of the synthetic vitamin C. Also, while most sub- stances are harmless at very low level of
intake, all (28)


substance -- even the elements that are essential to life -- can be dangerous if you overdo
them. Take water for example. Six or eight glasses a day will keep your body in good fluid balance.
But you can also be drown (29)


in it. Some people argue that individuals vary greatly (30)


in their need for nutrients, it cannot necessarily be stated any given amount is too much;
that is all (31)


relative.
But
since
there
is
little
solid
information
on
what
is
the
optimal
intake
of
any
essential nutrient in healthy individuals, it would be impossible to give guidelines that take these
proportional needs into the (32)


account. Just as with other drugs, the relation to (33)


different vitamin dosages varies, with some people better able than others to tolerate large
amounts. While we do know that very specifically what the toxic level (34)


is
for
vitamins
A
and
D,
we
are

about

The telephone system is a circuit-switched network. For much of the history of the system, when
you placed (26)


a call, you were renting a pair of copper wires that ran continuously from your telephone to
the other party’s phone. You had excluding use of those wires during the (27)



call; when you hung up, they were rented to someone else. Today the transaction is more
complicated. ( your call may well possess a fiber-optic cable or a satellite with hundreds of other
calls), but more conceptually the system (28)


still
works
the
same
way.
When
you
dial
the
phone,
you
get
a
private
connection
of
one
other party. This is an alternative network architecture called (29)


packet switching, in which all stations are always connected to the network, but they receive
only the messages addressed to them. It is as if your telephone was always tuned in to (30)


thousands of conversations going on the wire, but you (31)


heard only the occasional word intended to you. Most (32)


computer
networks
employ
packet
switching,
because
it
is
more
efficient
than
circuit
switching when traffic is heavy. It seems reasonable the existing packet-switched (33)


network will grow, and new one may be created; they could (34)


well absorb traffic that would otherwise go to the telephone system and thereby reduce the
need for telephone numbers. (35)

The
German
poet
and
polymath
Johann
Wolfgang
von
Goethe
pondered
the
question
of
how
organisms develop in his scientific studies of form and structure immature plants and animals, a
field he found and named morphology. His search for a single basic body plan (26)


across all life-forms led him to think about the prevalence of repeating (27)


segments in body structures. The spinal columns of fish, reptiles, (28)


birds and mammals, for instance, all are made of long strings of (29)


repeated vertebrae. Among invertebrates the growth of virtually identical segments is how
striking: in earthworms, for example, even (30)


internal
organs
are
repeated
in
serial
segments.
Likewise,
the
abdomen
of
flies
and other
insects are segmented, as are the (31)


successive
wormlike
articulations
in
crabs,
shrimps
and
other
crustaceans.
To
Goethe
the
evidence suggested that nature takes a building-block approach to generate life, repeating a basic
element (32)


again and again to arrive at a complicated organism. The only glaring (33)


hole he could see in the theory was the apparent lack of sort of (34)


segmentation in the vertebrate heads. In 1790 he hypothesized that (35)


spinal vertebrate is modified during the development to form the skull.

Literature is a means by which we know ourselves. By it we (26)


meet
future
selves,
and
recognize
past
selves;
against
it
we
match
our
present
self.
Its
primary
function
is
to
validate
and
re-create
the
self
in
all
its
individuality
and
distinctness.
In
doing so, it cements a sense of relationship between the self and the otherness of the book, and
allows us a notion of ourselves as sociable. Its shared knowledge is vicarious experience; by this
means we enlarge our understandings (27)


of what it means to be human, of the corporate and independent (28)


nature of human society. The act of reading the book marks both our difference in and our
place in the human fabric. The more we read, (29)


the more we are. In the act of reading silently we are alone from the (30) book, separate
from ones own immediate surroundings. Yet in the (31)


act of reading we enter other minds and other places, enlarge our (32)


dialogue with the world. Thus paradoxically, while disengaging from the immediate we are
increasing its scope. In silence, reading activates a deeply creative function of consciousness. We
are deeply committed to the narrative which we coexist while engaged in (33)


reading. All kinds of present physical discomfortness may be (34)


unnoticed
while
we
are
reading,
and
actual
time
is
replaced
by
narrative
time.
To
imaginatively enter a fictional world by reading it (35)


is then both a liberation from self and an expansion of self.

Because
the
air
in
the country
is
really
clean,
we ought
to
live
there
much
as
is
possible.
Since, however, a great deal of the worlds (26)


work must be done indoor in cities, it is important that we take every (27)


precaution
to
ventilate
our
houses
properly.
Some
people
have
thought
that
night
air
is
injurious. But careful study shows that night air is identical with that which we breath during the
day. In face the (28)


proper ventilation of a bedroom is one of the first necessity for good (29)


health. Since the exhaled air is usually warmer and lighter than the inhaled air, it rises to the
top of the room. Therefore it is better to open a window both at the top to let the warm up air
out and also at (30)


the bottom to admit the fresh air in. Of course, this does not mean (31)


that one should sleep in a strong draft. In many places it is feasible to sleep out-of-the-doors
on a sleeping porch and so to secure perfect (32)


ventilation.
In
recent
years
we
have
seen
steady
progress
made
in
the
development
of
equipments to supply proper conditioned air not only in large (33)


auditoriums, class-rooms, and factories, but also in railroad trains and in private homes. This
