Passage 1 `TM[7'
In contrast to traditional analyses of minority business, the sociological analysis contends kKV`9&dZe
that minority business ownership is a group-level phenomenon, in that it is largely dependent upon 1M|DaAI
social-group resources for its development. Specifically, this analysis indicates that support -r9G5Z
!|n
networks play a critical role in starting and maintaining minority business enterprises by providing QRs!B!Fn0
owners with a range of assistance, from the informal encouragement of family members and 9/rX%
friends to dependable sources of labor and clientele from the owner’s ethnic group. Such self-help ;?/v}$Pa
networks, which encourage and support ethnic minority entrepreneurs, consist of “primary” %&L]k>n^
institutions, those closest to the individual in shaping his or her behavior and beliefs. They are Z
h?1+Sz&
characterized by the face-to-face association and cooperation of persons united by ties of mutual k<xiP@b{y
concern. They form an intermediate social level between the individual and larger “secondary” \;w+_<zE5{
institutions based on impersonal relationships. Primary institutions comprising the support :NL.#!>/
network include kinship, peer, and neighborhood or community subgroups. k T$yHB #
A major function of self-help networks is financial support. Most scholars agree that minority rz c}2I
business owners have depended primarily on family funds and ethnic community resources for 'H0b1t1S%
investment capital. Personal savings have been accumulated, often through frugal living habits w$~|/UrLf
that require sacrifices by the entire family and are thus a product of long-term family financial 0ad -4
behavior. Additional loans and gifts from relatives, forthcoming because of group obligation 4qtjP8Zv[
rather than narrow investment calculation, have supplemented personal savings. Individual -ec~~95
entrepreneurs do not necessarily rely on their kin because they cannot obtain financial backing qGtXReK
from commercial resources. They may actually avoid banks because they assume that commercial 9QaEUy*,
institutions either cannot comprehend the special needs of minority enterprise or charge 5b9v`6Kq
unreasonably high interest rates. H
R$\jJ
Within the larger ethnic community, rotating credit associations have been used to raise vmI]N
capital. These associations are informal clubs of friends and other trusted members of the ethnic Fx']kn9
group who make regular contributions to a fund that is given to each contributor in rotation. One k$nQY
author estimates that 40 percent of New York Chinatown firms established during 1900-1950 lc/q0
utilized such associations as their initial source of capital. However, recent immigrants and third = :rR%L!a
or fourth generations of older groups now employ rotating credit associations only occasionally to DXj_\ R(}
raise investment funds. Some groups, like Black Americans, found other means of financial
KQ<pQkhv
support for their entrepreneurial efforts. The first Black-operated banks were created in the late `X8AM=
nineteenth century as depositories for dues collected from fraternal or lodge groups, which \HFeEEKH
themselves had sprung from Black churches. Black banks made limited investments in other Black (q+U5Ls6
enterprises. Irish immigrants in American cities organized many building and loan associations to ~ g$Pb[V
provide capital for home construction and purchase. They, in turn, provided work for many Irish BBy"qkTe
home-building contractor firms. Other ethnic and minority groups followed similar practices in hPt(7E2ke~
founding ethnic-directed financial institutions. PdG:aGQ>

Passage2 vqDd][ n
It was once assumed that all living things could be divided into two fundamental and q))rlMo
exhaustive categories. Multicellular plants and animals, as well as many unicellular organisms, are ]Q-*xho
eukaryotic—their large, complex cells have a well-formed nucleus and many organelles. On the $< &N#
other hand, the true bacteria are prokaryotic cell, which are simple and lack a nucleus. The P:,@2el
distinction between eukaryotes and bacteria, initially defined in terms of subcellular structures zi M~V'
visible with a microscope, was ultimately carried to the molecular level. Here prokaryotic and 0 8*bYJu
eukaryotic cells have many features in common. For instance, they translate genetic information I6!~(ND7
into proteins according to the same type of genetic coding. But even where the molecular
fX"cQ&
processes are the same, the details in the two forms are different and characteristic of the aYc*v5QN3
respective forms. For example, the amino acid sequences of various enzymes tend to be typically Xtv^q>!
prokaryotic or eukaryotic. The differences between the groups and the similarities within each AG?cI@',
group made it seem certain to most biologists that the tree of life had only two stems. Moreover, ;jC}.]
_)w
arguments pointing out the extent of both structural and functional differences between eukaryotes zF'LbQz0[
and true bacteria convinced many biologists that the precursors of the eukaryotes must have tS|gQUF17
diverged from the common ancestor before the bacteria arose. \C<|yD
Although much of this picture has been sustained by more recent research, it seems [N]5)n
fundamentally wrong in one respect. Among the bacteria, there are organisms that are PL*Mz(&bf
significantly different both from the cells of eukaryotes and from the true bacteria, and it now %#5yC|o9Pn
appears that there are three stems in the tree of life. New techniques for determining the molecular prJ]uH,
sequence of the RNA of organisms have produced evolutionary information about the degree to -%R3YU3
which organisms are related, the time since they diverged from a common ancestor, and the hsYS<]
reconstruction of ancestral versions of genes. These techniques have strongly suggested that L;jzDng<
although the true bacteria indeed form a large coherent group, certain other bacteria, the Yi?X|"\`
archaebacteria, which are also prokaryotes and which resemble true bacteria, represent a distinct v D"4a
w
evolutionary branch that far antedates the common ancestor of all true bacteria. \9r1JP0
1. The passage is primarily concerned with `XT8}9z!
(A) detailing the evidence that has led most biologists to replace the trichotomous picture of ST'eJ5P7!5
living organisms with a dichotomous one LmCr[9/
(B) outlining the factors that have contributed to the current hypothesis concerning the number of K=S-p3\g
basic categories of living organisms VTM*=5|c
(C) evaluating experiments that have resulted in proof that the prokaryotes are more ancient than ^tp6G
had been expected :.2Tcq
(D) summarizing the differences in structure and function found among true bacteria, _SVIY@K

archaebacteria, and eukaryotes hh%fmc
(E) formulating a hypothesis about the mechanisms of evolution that resulted in the ancestors of h`{agWB
the prokaryotes >d/DXv

2. According to the passage, investigations of eukaryotic and prokaryotic cells at the molecular |DB7o+4
level supported the conclusion that ^v5v7\!
(A) most eukaryotic organisms are unicellular WR5@S&fU`
(B) complex cells have well-formed nuclei yaDK_fk
(C) prokaryotes and eukaryotes form two fundamental categories roiUVisq*
(D) subcellular structures are visible with a microscope (L{>la!

3. According to the passage, which of the following statements about the two-category #Qir%\*V
hypothesis is likely to be true? q:iB}ch5R
(A) It is promising because it explains the presence of true bacteria-like organisms such as .zm/GtOV@
organelles in eukaryotic cells. ON.1'Wk?
(B) It is promising because it explains why eukaryotic cells, unlike prokaryotic cells, tend to pUp&eH
form multicellular organisms. lMn1e6~K
(C) It is flawed because it fails to account for the great variety among eukaryotic organisms. S)n+E\c
