When college students were asked about their experiences in childhood, those who remembere

than limit the number of people they hire, trading firms aim to hire all those applicants who are able to be successful and to reject the rest. By this standard Quinsey-Leerheims record is perfect. All of its entry-level hirees over the past decade have become successful commodity traders. Which of the following, if true, would cast the most doubt on the assessment given above of Quinsey-Leerheim s hiring performance?

A．Over the past decade, Quinsey-Leerheim"s trading practices and policies have changed in a way that gives much more responsibility to individual traders.

B．Since the pool of entry-level applicants is mostly the same for all commodity-trading firms, Quinsey-Leerheim often competes with other trading firms for the strongest applicants.

C．Quinsey-Leerheim rejects some entry-level applicants who go on to become extremely successful commodity traders with other trading firms.

D．Commodity trading requires skills that are needed in very few other occupations, so that trading firms" hiring procedures typically differ significantly from those of other financial firms.

E．Commodity trading is very stressful, and even successful commodity traders rarely work as traders for longer than ten years, although they often earn substantial sums in those years.

pends on which of the following?

n which of the following ways?

A．It may furnish a valid account of ore-forming processes, and, hence, can support conceptual models that have great practical significance.

B．It suggests that certain geological formations, long believed to be mineralized, are in fact mineralized, thus confirming current conceptual models.

C．It suggests that there may not be enough similarity across Archean-age gold-quartz vein systems to warrant the formulation of conceptual models.

D．It corrects existing theories about the chemical halos of gold deposits, and thus provides a basis for correcting current conceptual models.

E．It suggests that simple prospecting methods still have a higher success rate in the discovery of gold deposits than do more modern methods.

Native Americans conducted during the nineteenth century was the use of which of the following?

A．Investigators familiar with the culture under study

B．A language other than the informant’s for recording life stories

C．Life stories as the ethnologist’s primary source of information

D．Complete transcriptions of informants’ descriptions of tribal beliefs

E．Stringent guidelines for the preservation of cultural data

At the end of the nineteenth century, a rising interest

in Native American customs and an increasing desire to

understand Native American culture prompted ethnolo-

gists to begin recording the life stories of Native Amer-

(5) ican. Ethnologists had a distinct reason for wanting to

hear the stories: they were after linguistic or anthropo-

logical data that would supplement their own field

observations, and they believed that the personal

stories, even of a single individual, could increase their

(10) understanding of the cultures that they had been

observing from without. In addition many ethnologists

at the turn of the century believed that Native Amer-

ican manners and customs were rapidly disappearing,

and that it was important to preserve for posterity as

(15) much information as could be adequately recorded

before the cultures disappeared forever.

There were, however, arguments against this method

as a way of acquiring accurate and complete informa-

tion. Franz Boas, for example, described autobiogra-

(20) phies as being “of limited value, and useful chiefly for

the study of the perversion of truth by memory,” while

Paul Radin contended that investigators rarely spent

enough time with the tribes they were observing, and

inevitably derived results too tinged by the investi-

(25) gator’s own emotional tone to be reliable.

Even more importantly, as these life stories moved

from the traditional oral mode to recorded written

form, much was inevitably lost. Editors often decided

what elements were significant to the field research on a

(30) given tribe. Native Americans recognized that the

essence of their lives could not be communicated in

English and that events that they thought significant

were often deemed unimportant by their interviewers.

Indeed, the very act of telling their stories could force

(35) Native American narrators to distort their cultures, as

taboos had to be broken to speak the names of dead

relatives crucial to their family stories.

Despite all of this, autobiography remains a useful

tool for ethnological research: such personal reminis-

(40) cences and impressions, incomplete as they may be, are

likely to throw more light on the working of the mind

and emotions than any amount of speculation from an

ethnologist or ethnological theorist from another

culture.
