Passage 1 k6GQH@y!
In contrast to traditional analyses of minority business, the sociological analysis contends Ux{QYjFE
that minority business ownership is a group-level phenomenon, in that it is largely dependent upon 5|t-CY{?b
social-group resources for its development. Specifically, this analysis indicates that support e=Ib
Em{|
networks play a critical role in starting and maintaining minority business enterprises by providing nD>X?yz2
owners with a range of assistance, from the informal encouragement of family members and zf5%|7o
friends to dependable sources of labor and clientele from the owner’s ethnic group. Such self-help 8wZ
$Hq
networks, which encourage and support ethnic minority entrepreneurs, consist of “primary” 9&<c
)sS&B
institutions, those closest to the individual in shaping his or her behavior and beliefs. They are ,?Vxcr
characterized by the face-to-face association and cooperation of persons united by ties of mutual z|Xt'?9&n
concern. They form an intermediate social level between the individual and larger “secondary” s|
Vs#o.P)
institutions based on impersonal relationships. Primary institutions comprising the support +W8#] u|
network include kinship, peer, and neighborhood or community subgroups. xdY'i0fh
A major function of self-help networks is financial support. Most scholars agree that minority t\!5$P
business owners have depended primarily on family funds and ethnic community resources for 1D
L+=-
investment capital. Personal savings have been accumulated, often through frugal living habits (Ia:>ocE0
that require sacrifices by the entire family and are thus a product of long-term family financial .>PwbZ
behavior. Additional loans and gifts from relatives, forthcoming because of group obligation Z/v )^VR
rather than narrow investment calculation, have supplemented personal savings. Individual e%{7CR'~TD
entrepreneurs do not necessarily rely on their kin because they cannot obtain financial backing 9)j"|5H
from commercial resources. They may actually avoid banks because they assume that commercial s k~7"v{Y.
institutions either cannot comprehend the special needs of minority enterprise or charge j.+,c#hFo
unreasonably high interest rates. Y2N$&]O{
Within the larger ethnic community, rotating credit associations have been used to raise 2"P1I
capital. These associations are informal clubs of friends and other trusted members of the ethnic -(}N-yu
group who make regular contributions to a fund that is given to each contributor in rotation. One -~lrv#5Q
author estimates that 40 percent of New York Chinatown firms established during 1900-1950 irjHPuhcG
utilized such associations as their initial source of capital. However, recent immigrants and third BCd0X. m(
or fourth generations of older groups now employ rotating credit associations only occasionally to !4t%\N6Ib
raise investment funds. Some groups, like Black Americans, found other means of financial t
o#2.
support for their entrepreneurial efforts. The first Black-operated banks were created in the late o(t`XE['<
nineteenth century as depositories for dues collected from fraternal or lodge groups, which *0'{n*>
themselves had sprung from Black churches. Black banks made limited investments in other Black v{\~>1J{
enterprises. Irish immigrants in American cities organized many building and loan associations to g K dNgU
provide capital for home construction and purchase. They, in turn, provided work for many Irish a{?>F&vnU
home-building contractor firms. Other ethnic and minority groups followed similar practices in
$.B}zY{
founding ethnic-directed financial institutions. &N%-.&t'

Passage2 vd9><W
It was once assumed that all living things could be divided into two fundamental and lM5Xw
exhaustive categories. Multicellular plants and animals, as well as many unicellular organisms, are
t3b%f`D
eukaryotic—their large, complex cells have a well-formed nucleus and many organelles. On the R
I"A'/56
other hand, the true bacteria are prokaryotic cell, which are simple and lack a nucleus. The Llk4 =p
distinction between eukaryotes and bacteria, initially defined in terms of subcellular structures cSBYC_LU
visible with a microscope, was ultimately carried to the molecular level. Here prokaryotic and ".eD&oX{
eukaryotic cells have many features in common. For instance, they translate genetic information 0zaE?dA]
into proteins according to the same type of genetic coding. But even where the molecular =LS?:Mhm
processes are the same, the details in the two forms are different and characteristic of the @
Sw[+`
respective forms. For example, the amino acid sequences of various enzymes tend to be typically ^'~+ w3M@
prokaryotic or eukaryotic. The differences between the groups and the similarities within each ayuj)]b
group made it seem certain to most biologists that the tree of life had only two stems. Moreover, ]z,W1Zs?
arguments pointing out the extent of both structural and functional differences between eukaryotes 1_!*R]a q
and true bacteria convinced many biologists that the precursors of the eukaryotes must have Zycu3%JI
diverged from the common ancestor before the bacteria arose. Y6/'gg'&5
Although much of this picture has been sustained by more recent research, it seems X 6/k `J
fundamentally wrong in one respect. Among the bacteria, there are organisms that are YsXP$y]g-
significantly different both from the cells of eukaryotes and from the true bacteria, and it now "*WzoRA={
appears that there are three stems in the tree of life. New techniques for determining the molecular 9Nglt3J[
sequence of the RNA of organisms have produced evolutionary information about the degree to C XZm/^
which organisms are related, the time since they diverged from a common ancestor, and the it!8+hvq9*
reconstruction of ancestral versions of genes. These techniques have strongly suggested that Jeyy Z=
although the true bacteria indeed form a large coherent group, certain other bacteria, the Hm4:m$=p
4
archaebacteria, which are also prokaryotes and which resemble true bacteria, represent a distinct V4}9f5FR
evolutionary branch that far antedates the common ancestor of all true bacteria. G:$wdT(u
1. The passage is primarily concerned with
%lAJ]$m
(A) detailing the evidence that has led most biologists to replace the trichotomous picture of
SEF/D0
living organisms with a dichotomous one
DHJh.Y@H
(B) outlining the factors that have contributed to the current hypothesis concerning the number of c$Js<[1
basic categories of living organisms |_8-3
(C) evaluating experiments that have resulted in proof that the prokaryotes are more ancient than CE:TQzg
had been expected ZkkXITQkPM
(D) summarizing the differences in structure and function found among true bacteria, %p)6m2Sb
archaebacteria, and eukaryotes `UL#g![J
(E) formulating a hypothesis about the mechanisms of evolution that resulted in the ancestors of dX: (%_Mn
the prokaryotes 0#KDvCBJ
2. According to the passage, investigations of eukaryotic and prokaryotic cells at the molecular +.whEw(i
