Passage 1 S,Y\ox-
In contrast to traditional analyses of minority business, the sociological analysis contends R
4= ~
that minority business ownership is a group-level phenomenon, in that it is largely dependent upon rMV<}C ^
social-group resources for its development. Specifically, this analysis indicates that support E{):zg
networks play a critical role in starting and maintaining minority business enterprises by providing w+^z{3>
owners with a range of assistance, from the informal encouragement of family members and E~[v.3`
friends to dependable sources of labor and clientele from the owner’s ethnic group. Such self-help z8MKGM
networks, which encourage and support ethnic minority entrepreneurs, consist of “primary” d9@Pze">e
institutions, those closest to the individual in shaping his or her behavior and beliefs. They are -XbO[_Wf
characterized by the face-to-face association and cooperation of persons united by ties of mutual 7v{X?86&
concern. They form an intermediate social level between the individual and larger “secondary”
Sj,>O:p
institutions based on impersonal relationships. Primary institutions comprising the support Qp]-:b
network include kinship, peer, and neighborhood or community subgroups. 0 It[Pa qG
A major function of self-help networks is financial support. Most scholars agree that minority >vr!3
business owners have depended primarily on family funds and ethnic community resources for IY* ~df
investment capital. Personal savings have been accumulated, often through frugal living habits {[
E7Cf
that require sacrifices by the entire family and are thus a product of long-term family financial Y6&B%t<bo
behavior. Additional loans and gifts from relatives, forthcoming because of group obligation 1\hh,s
rather than narrow investment calculation, have supplemented personal savings. Individual q? 9x0L
entrepreneurs do not necessarily rely on their kin because they cannot obtain financial backing :!fP~(R'm
from commercial resources. They may actually avoid banks because they assume that commercial *5Mg^}ZC5
institutions either cannot comprehend the special needs of minority enterprise or charge Syf0dp3
unreasonably high interest rates. h2K
x
Within the larger ethnic community, rotating credit associations have been used to raise eD#R4
capital. These associations are informal clubs of friends and other trusted members of the ethnic %T_4n^beFQ
group who make regular contributions to a fund that is given to each contributor in rotation. One }mhD2 ' E
author estimates that 40 percent of New York Chinatown firms established during 1900-1950 P%CNu
utilized such associations as their initial source of capital. However, recent immigrants and third _QS +{
or fourth generations of older groups now employ rotating credit associations only occasionally to RD$"ft]Vc
raise investment funds. Some groups, like Black Americans, found other means of financial MDyPwv\
support for their entrepreneurial efforts. The first Black-operated banks were created in the late ljS~>&
nineteenth century as depositories for dues collected from fraternal or lodge groups, which >3{l"SPU
themselves had sprung from Black churches. Black banks made limited investments in other Black hYj!*P)uV
enterprises. Irish immigrants in American cities organized many building and loan associations to c~bTK"
u
provide capital for home construction and purchase. They, in turn, provided work for many Irish \Y?ByY
home-building contractor firms. Other ethnic and minority groups followed similar practices in D:r+3w:l]
founding ethnic-directed financial institutions. 8M"0o}wx

Passage2 yOQEF\
It was once assumed that all living things could be divided into two fundamental and fho$:S
exhaustive categories. Multicellular plants and animals, as well as many unicellular organisms, are \`MX\OR
eukaryotic—their large, complex cells have a well-formed nucleus and many organelles. On the UyWKE<
other hand, the true bacteria are prokaryotic cell, which are simple and lack a nucleus. The Z
^w5x :
distinction between eukaryotes and bacteria, initially defined in terms of subcellular structures HfN:oww
visible with a microscope, was ultimately carried to the molecular level. Here prokaryotic and 2 ~zo)G0
eukaryotic cells have many features in common. For instance, they translate genetic information j. m(Z}
into proteins according to the same type of genetic coding. But even where the molecular \i
+=tGY
processes are the same, the details in the two forms are different and characteristic of the DKzP)!B "
respective forms. For example, the amino acid sequences of various enzymes tend to be typically
Du*O|
prokaryotic or eukaryotic. The differences between the groups and the similarities within each pH'1be{K
group made it seem certain to most biologists that the tree of life had only two stems. Moreover, 2S{IZ]
arguments pointing out the extent of both structural and functional differences between eukaryotes @NY$.K#]
and true bacteria convinced many biologists that the precursors of the eukaryotes must have c/g"/ICs
diverged from the common ancestor before the bacteria arose. ^&|$&7
Although much of this picture has been sustained by more recent research, it seems .).*6{_
fundamentally wrong in one respect. Among the bacteria, there are organisms that are @Qa)@'u
significantly different both from the cells of eukaryotes and from the true bacteria, and it now fV`R7m.
appears that there are three stems in the tree of life. New techniques for determining the molecular j1LL[+G-"_
sequence of the RNA of organisms have produced evolutionary information about the degree to S(5aJ[7Zm
which organisms are related, the time since they diverged from a common ancestor, and the GsG9;6c+u
reconstruction of ancestral versions of genes. These techniques have strongly suggested that ?D^l&`S
although the true bacteria indeed form a large coherent group, certain other bacteria, the j
(8I+||
archaebacteria, which are also prokaryotes and which resemble true bacteria, represent a distinct &;)6G1X1
evolutionary branch that far antedates the common ancestor of all true bacteria. e?&4;
1. The passage is primarily concerned with kp+\3z_
(A) detailing the evidence that has led most biologists to replace the trichotomous picture of otsINAizgS
living organisms with a dichotomous one 9bpY>ze
(B) outlining the factors that have contributed to the current hypothesis concerning the number of "I|[m%\
basic categories of living organisms Xu1tN9:oE
(C) evaluating experiments that have resulted in proof that the prokaryotes are more ancient than )I`6XG
had been expected O*<,lq 0K
(D) summarizing the differences in structure and function found among true bacteria, ={a8=E!;
archaebacteria, and eukaryotes k($N_XlE
(E) formulating a hypothesis about the mechanisms of evolution that resulted in the ancestors of =a_B' ^`L
the prokaryotes @jE<V=?
2. According to the passage, investigations of eukaryotic and prokaryotic cells at the molecular XG5mfKMt+
level supported the conclusion that IEB|Y
(A) most eukaryotic organisms are unicellular !50Fue^JM
(B) complex cells have well-formed nuclei NA,)FmQjk
(C) prokaryotes and eukaryotes form two fundamental categories | Wrf|%p
(D) subcellular structures are visible with a microscope Q6cF<L`bW
(E) prokaryotic and eukaryotic cells have similar enzymes v:YW[THre
3. According to the passage, which of the following statements about the two-category nKFua l3
hypothesis is likely to be true? \h%/Cp+p
(A) It is promising because it explains the presence of true bacteria-like organisms such as cTKj1)!z?X
organelles in eukaryotic cells. 8"a[W3b
(B) It is promising because it explains why eukaryotic cells, unlike prokaryotic cells, tend to ]F@XGJN
form multicellular organisms. g`jO
(C) It is flawed because it fails to account for the great variety among eukaryotic organisms. t`
R#pQ
(D) It is flawed because it fails to account for the similarity between prokaryotes and eukaryotes. r@3VN~
(E) It is flawed because it fails to recognize an important distinction among prokaryotes. D]9I-|
4. It can be inferred from the passage that which of the following have recently been compared _u^ S[
in order to clarify the fundamental classifications of living things? R4<
