Passage 1 [s~JceUyX
In contrast to traditional analyses of minority business, the sociological analysis contends zI:(33
)
that minority business ownership is a group-level phenomenon, in that it is largely dependent upon )s7bJjT0=X
social-group resources for its development. Specifically, this analysis indicates that support q]
px
(
networks play a critical role in starting and maintaining minority business enterprises by providing ~n
WsP}`n
owners with a range of assistance, from the informal encouragement of family members and
Y
%K~w
friends to dependable sources of labor and clientele from the owner’s ethnic group. Such self-help lW
p~t
networks, which encourage and support ethnic minority entrepreneurs, consist of “primary” mj@31YW
institutions, those closest to the individual in shaping his or her behavior and beliefs. They are +0J@y1
characterized by the face-to-face association and cooperation of persons united by ties of mutual Z==!C=SBv
concern. They form an intermediate social level between the individual and larger “secondary” VJDoH
institutions based on impersonal relationships. Primary institutions comprising the support , 9mgY
p2
network include kinship, peer, and neighborhood or community subgroups. 0#QKVZq2>
A major function of self-help networks is financial support. Most scholars agree that minority 4U?<vby
business owners have depended primarily on family funds and ethnic community resources for Pp+~Cir
investment capital. Personal savings have been accumulated, often through frugal living habits (?\?it-
that require sacrifices by the entire family and are thus a product of long-term family financial T"?Y5t`(
behavior. Additional loans and gifts from relatives, forthcoming because of group obligation `FZF2.N
rather than narrow investment calculation, have supplemented personal savings. Individual ;WD,x:>blO
entrepreneurs do not necessarily rely on their kin because they cannot obtain financial backing l-}KmZ]
from commercial resources. They may actually avoid banks because they assume that commercial %x
2uP9
institutions either cannot comprehend the special needs of minority enterprise or charge |O-`5_z$r
unreasonably high interest rates. GAw(mH*
Within the larger ethnic community, rotating credit associations have been used to raise i5"5&r7r
capital. These associations are informal clubs of friends and other trusted members of the ethnic &vkjmiAS
group who make regular contributions to a fund that is given to each contributor in rotation. One l$a?A[M$
author estimates that 40 percent of New York Chinatown firms established during 1900-1950 =A@>I0(7
utilized such associations as their initial source of capital. However, recent immigrants and third +@ MPQv
or fourth generations of older groups now employ rotating credit associations only occasionally to d
yh<pX/$
raise investment funds. Some groups, like Black Americans, found other means of financial XWUP= D~
support for their entrepreneurial efforts. The first Black-operated banks were created in the late >;4!O%F
nineteenth century as depositories for dues collected from fraternal or lodge groups, which p|3b/plZ
themselves had sprung from Black churches. Black banks made limited investments in other Black

enterprises. Irish immigrants in American cities organized many building and loan associations to &nY;=Hv`WY
provide capital for home construction and purchase. They, in turn, provided work for many Irish 7 Wl-n
home-building contractor firms. Other ethnic and minority groups followed similar practices in 83 I-X95
founding ethnic-directed financial institutions. >2b`\Q*<

Passage2 ILGMMA_2
It was once assumed that all living things could be divided into two fundamental and <StN%2WQ1
exhaustive categories. Multicellular plants and animals, as well as many unicellular organisms, are 3j\1S1
eukaryotic—their large, complex cells have a well-formed nucleus and many organelles. On the B} lvr-c#
other hand, the true bacteria are prokaryotic cell, which are simple and lack a nucleus. The Mu+0<>
distinction between eukaryotes and bacteria, initially defined in terms of subcellular structures Qk:Y2mL
visible with a microscope, was ultimately carried to the molecular level. Here prokaryotic and wne,e's}
eukaryotic cells have many features in common. For instance, they translate genetic information Xu%'Z".>:
into proteins according to the same type of genetic coding. But even where the molecular wB.&}p9p
processes are the same, the details in the two forms are different and characteristic of the &5yVxL:
respective forms. For example, the amino acid sequences of various enzymes tend to be typically SLa>7`<Q
prokaryotic or eukaryotic. The differences between the groups and the similarities within each As'=tIro
group made it seem certain to most biologists that the tree of life had only two stems. Moreover, o]4*|ARPs
arguments pointing out the extent of both structural and functional differences between eukaryotes E|iQc8gr&
and true bacteria convinced many biologists that the precursors of the eukaryotes must have .+$Q<L
diverged from the common ancestor before the bacteria arose. 9Z4nAc
Although much of this picture has been sustained by more recent research, it seems ]s<[D$ <,
fundamentally wrong in one respect. Among the bacteria, there are organisms that are 2LF/H$]o5
significantly different both from the cells of eukaryotes and from the true bacteria, and it now .P8&5i)'P,
appears that there are three stems in the tree of life. New techniques for determining the molecular pR=@S>!|
sequence of the RNA of organisms have produced evolutionary information about the degree to G?O1>?4C
which organisms are related, the time since they diverged from a common ancestor, and the X%
t1T4
reconstruction of ancestral versions of genes. These techniques have strongly suggested that F3On?x)
although the true bacteria indeed form a large coherent group, certain other bacteria, the k\5c|Wq|g
archaebacteria, which are also prokaryotes and which resemble true bacteria, represent a distinct 9jM}~XvV
evolutionary branch that far antedates the common ancestor of all true bacteria. KcWN,!G
