Passage 1 '_dzcN,z
In contrast to traditional analyses of minority business, the sociological analysis contends piOXo=9H.
that minority business ownership is a group-level phenomenon, in that it is largely dependent upon 'Hw4j:pS
social-group resources for its development. Specifically, this analysis indicates that support JQ@fuo %
networks play a critical role in starting and maintaining minority business enterprises by providing t|V0x3X
owners with a range of assistance, from the informal encouragement of family members and *XbI#L%>
friends to dependable sources of labor and clientele from the owner’s ethnic group. Such self-help ][d,l\gu+s
networks, which encourage and support ethnic minority entrepreneurs, consist of “primary” |9Yi7.
institutions, those closest to the individual in shaping his or her behavior and beliefs. They are !"Q}R p
characterized by the face-to-face association and cooperation of persons united by ties of mutual fj>C@p
concern. They form an intermediate social level between the individual and larger “secondary” Ri#H.T<'
institutions based on impersonal relationships. Primary institutions comprising the support O oSb>Y/4
network include kinship, peer, and neighborhood or community subgroups. 2 -Xdoxw
A major function of self-help networks is financial support. Most scholars agree that minority cu&,J#r%
business owners have depended primarily on family funds and ethnic community resources for <YFY{VC(
investment capital. Personal savings have been accumulated, often through frugal living habits <
?h%k"5
that require sacrifices by the entire family and are thus a product of long-term family financial }CDk
9Xk
behavior. Additional loans and gifts from relatives, forthcoming because of group obligation AW,OHSXh6
rather than narrow investment calculation, have supplemented personal savings. Individual "&~
0T#
entrepreneurs do not necessarily rely on their kin because they cannot obtain financial backing e-5?p~>
from commercial resources. They may actually avoid banks because they assume that commercial bU54-3Ox*
institutions either cannot comprehend the special needs of minority enterprise or charge G{9X)|d
unreasonably high interest rates. [xb]Wf
Within the larger ethnic community, rotating credit associations have been used to raise x9W(cKB'S
capital. These associations are informal clubs of friends and other trusted members of the ethnic O
5Nb
group who make regular contributions to a fund that is given to each contributor in rotation. One ,#]t$mzbQ(
author estimates that 40 percent of New York Chinatown firms established during 1900-1950 ^Q+i=y{W
utilized such associations as their initial source of capital. However, recent immigrants and third J#2!ZQE
3
or fourth generations of older groups now employ rotating credit associations only occasionally to qTQ!jN
raise investment funds. Some groups, like Black Americans, found other means of financial B>y9fI
support for their entrepreneurial efforts. The first Black-operated banks were created in the late }/P5>F<H[
nineteenth century as depositories for dues collected from fraternal or lodge groups, which ]aryV?!
6
themselves had sprung from Black churches. Black banks made limited investments in other Black kcie}Be
enterprises. Irish immigrants in American cities organized many building and loan associations to 2[fN\e{
provide capital for home construction and purchase. They, in turn, provided work for many Irish f.B>&%JRZ
home-building contractor firms. Other ethnic and minority groups followed similar practices in A@*:<Hs%
founding ethnic-directed financial institutions. '3IC*o"

Passage2 Zfyo-Wk
It was once assumed that all living things could be divided into two fundamental and s+Q~~]HJM
exhaustive categories. Multicellular plants and animals, as well as many unicellular organisms, are r3>i+i42
eukaryotic—their large, complex cells have a well-formed nucleus and many organelles. On the F{UP;"8'
other hand, the true bacteria are prokaryotic cell, which are simple and lack a nucleus. The p1vp8p
distinction between eukaryotes and bacteria, initially defined in terms of subcellular structures @'|)~,"bx
visible with a microscope, was ultimately carried to the molecular level. Here prokaryotic and $ibuWb"a
eukaryotic cells have many features in common. For instance, they translate genetic information / 4lvP
into proteins according to the same type of genetic coding. But even where the molecular f"St&q>[s
processes are the same, the details in the two forms are different and characteristic of the @WI2hHD
respective forms. For example, the amino acid sequences of various enzymes tend to be typically {Lm~r+
U
prokaryotic or eukaryotic. The differences between the groups and the similarities within each 8HP6+c%
group made it seem certain to most biologists that the tree of life had only two stems. Moreover, N2w"R{) j\
arguments pointing out the extent of both structural and functional differences between eukaryotes {6}eN|4~#
and true bacteria convinced many biologists that the precursors of the eukaryotes must have HcqfB NM
diverged from the common ancestor before the bacteria arose. A*um{E+
Although much of this picture has been sustained by more recent research, it seems xe*aC
fundamentally wrong in one respect. Among the bacteria, there are organisms that are q=#}
yEG
significantly different both from the cells of eukaryotes and from the true bacteria, and it now &SrO)
appears that there are three stems in the tree of life. New techniques for determining the molecular :duo#w"K
sequence of the RNA of organisms have produced evolutionary information about the degree to T8HF|%I
which organisms are related, the time since they diverged from a common ancestor, and the xl#LrvxI
reconstruction of ancestral versions of genes. These techniques have strongly suggested that [h,Q Bz
although the true bacteria indeed form a large coherent group, certain other bacteria, the )4&cph';
archaebacteria, which are also prokaryotes and which resemble true bacteria, represent a distinct h}xeChw]
evolutionary branch that far antedates the common ancestor of all true bacteria. %wSj%>&-R
1. The passage is primarily concerned with 4vwTs*eB`
(A) detailing the evidence that has led most biologists to replace the trichotomous picture of IEzaK
living organisms with a dichotomous one FD8N"p
(B) outlining the factors that have contributed to the current hypothesis concerning the number of WASU0
basic categories of living organisms +9")KQT
(C) evaluating experiments that have resulted in proof that the prokaryotes are more ancient than 9F*+YG!
had been expected `3hSLR
(D) summarizing the differences in structure and function found among true bacteria, o5Q{/
archaebacteria, and eukaryotes /<]{KI
(E) formulating a hypothesis about the mechanisms of evolution that resulted in the ancestors of $]/Zxd
the prokaryotes Ba/Yl
2. According to the passage, investigations of eukaryotic and prokaryotic cells at the molecular `4~H/'%QB
