Typically the queen honey bee is mother to all the bees in a hive: after
mating with several male drones from other colonies, she lays fertilizedeggs that develop into all-female worker bees and lays
(5) unfertilized eggs that become all-male drones. When a queen dies, workers often lay unfertilized eggs that hatch into drones. Yet workers
rarely reproduce while a queen reigns. According to natural selection theory, a worker (10) would enhance her
fitness- or ability to propagate her genes- by hatching her own eggs inaddition to or in place of the queen's. But a typical worker's fitness wouldbe diminished if other workers' sons, who have less genetic material incommon with the
(15) worker, supplanted the queen's sons (the worker's brothers). Researchers, testing the hypothesis that workers usually somehowblockeach other's attempts to reproduce put unfertilized eggs laid by workers
and by the queen into a hive. Other workers (20) quickly devouredtheworkers' eggs while leaving the queen's eggs alone.

16. The author refers to the experiment described in lines 16-19 in order
to
A explain how worker bees are prevented from mating with drones
B explain how worker bees hatch and nurture the queen's young
C demonstrate the universality of natural selection
D show that worker bees are capable of thwarting each other's attempts to reproduce

Typically the queen honey bee is mother to all the bees in a hive: after
mating with several male drones from other colonies, she lays fertilizedeggs that develop into all-female worker bees and lays
(5) unfertilized eggs that become all-male drones. When a queen dies, workers often lay unfertilized eggs that hatch into drones. Yet workers
rarely reproduce while a queen reigns. According to natural selection theory, a worker (10) would enhance her
fitness- or ability to propagate her genes- by hatching her own eggs inaddition to or in place of the queen's. But a typical worker's fitness wouldbe diminished if other workers' sons, who have less genetic material incommon with the
(15) worker, supplanted the queen's sons (the worker's brothers). Researchers, testing the hypothesis that workers usually somehowblockeach other's attempts to reproduce put unfertilized eggs laid by workers
and by the queen into a hive. Other workers (20) quickly devouredtheworkers' eggs while leaving the queen's eggs alone

17. The passage suggests which of the following about the eggs laidbyworker bees?
A One of the eggs hatches into the next queen.                                                                                                   B The eggs are invariably destroyed by other worker bees.                                                                               C Each worker tries to hide her eggs from the other worker bees                                                                  D The eggs hatch only if the worker has mated with a drone fromanother
hive.

Analyzing the physics of dance can add fundamentally to a dancer's skill. Although dancer seldom see themselves totally in physical terms- as bodymass moving through space under the influence of well-known (5) forcesand obeying physical laws- neither can they afford to ignore the physicsof movement. For example, no matter how much a dancer wishes toleapoff the floor and then start turning, the law of conservation of angular
momentum absolutely prevents such a (10) movement
Some movements involving primarily vertical or horizontal motions of
the body as a whole, in which rotations can be ignored, can be studiedusing simple equations of linear motions in three dimensions. How-
(15) ever, rotational motions require more complex approaches that
involve analyses of the way the body's mass is distributed, the axes of
rotation involved in different types of movement, and the sources of theforces that produce the rotational movement.

18. The primary purpose of the passage is to
A initiate a debate over two approaches to analyzing a field of study                                                          B describe how one field of knowledge can be applied to another field                                                             C point out the contradictions between two distinct theories
D define and elaborate on an accepted scientific principle

Although a historical lack of access to formal
Spanish-language education initially limited the opportunities of someChicanos to hone their skills as writers of Spanish, their bilingual cultureclearly fostered as (5) exuberant and compelling oral tradition. It has thusgenerally been by way of the emphasis on oral literary creativity that
these Chicano writers, whose Englich language works are sometimes
uninspired, developed the powerful and arresting language that
characterized (10) their Spanish-language works. This Spanish-Englishdifference is not surprising. When writing in Spanish, these authors
stayed close to the spoken traditions of their communities where
publication, support, and instructive response would come quicklyinlocal or(15) regional newspapers. Works in English, however, oftenrequired the elimination of nuance or colloquialism, the adoption of aformal tone, and the adjustment of themes or ideas to satisfy the different
demands of national publications.

20. The passage is primarily concerned with doing which of the following?                                                 A Debating the historical value of a literary movement
B Describing and accounting for a difference in literary styles
D Explaining a publishing decision and evaluating its results
D Analyzing the expectations of a particular group of readers

21. The passage suggests that which of the following was probablycharacteristic of the "national publications" mentioned in line 19?
A They primarily presented scholarly material of little interest to a
general audience.                                                                                                                                                     B They sometimes published articles treating controversial themes.                                                          C They encouraged authors to feature local issues in articles in order toincrease circulation.                   D They took a stylistically formal approach to material of interest toageneral audience

While it is true that living organisms are profoundly affected by their
environment, (it is equally important to remember that many organisms
are also capable of altering their habitat significantly, some(5) times
limiting their own growth. The influence of the biological component of
an ecosystem is often greater in fresh waters than in marine or terrestrial
systems, because of the small size of many freshwater bodies. Manyof
the important effects of organisms (10) are related to their physiology, especially growth and respiration. By their growth many species candeplete essential nutrients within the system, thus limiting their owngrowth or that of other species. Land has demonstrated that in Lake
Windermere the algae itself has created. Once a year, in the spring, this
plant starts to grow rapidly in the lake, using up so much silica fromthewater that by late spring there is no longer enough to maintain its oval
growth. The population decreases dramatically as a result.

22. Which of the following is an example of the type of organismdescribed in lines 2-5?
A A kind of ant that feeds on the sweet juice exuded by the twigs of aspecies of thorn tree that grow in dry areas
B A kind of fish that, after growing to maturity in the ocean, returntofresh water
C A kind of flower that has markings distinctly perceptible in ultraviolet
light to the species of bee that pollinates the flowers
D A kind of tree with seeds that germinate readily only in a sunny spot
and then develop into mature trees that shade the area belowthem

The enduring power of certain concepts and beliefs, despite changes intheir outward manifestation, is a testament to their fundamental value. This phenomenon, where core principles transcend their initial structures, accounts for the persistence of certain universal ideas. Rabbi Meir, a
second-century scholar, admonished his disciples to look not at the (5)
**pitcher but at its contents** because, he stated, "Many a newpitcher
has been found to be full of old wine." This was his way of emphasizingthe importance of the distinction between **form and idea** and of
stressing that the **integrity of an idea is more important than the (10)
form of its expression**. Creative ideas not only produce their own instruments of survival as timeand circumstances demand, but permit the substitution of newforms for
old under the pressure of changed circumstances. (15) For example, **democracy**, as an idea, originated in ancient Greece and was carriedfrom there to Western Europe and the Americas. But it did not retaintheancient Greek form: it passed through several reforming processes andexists today in many (20) countries. Democratic governments differ inform because democracy is in principle **dynamic** and has thereforeresponded to local needs.

A Ancient Greece
