I'll try to post some good passages under this series...[good = GMAT contender]


Here is the first one...



One proposal for preserving
rain forests is to

promote the adoption of

Line new agricultural technolo-

(5) gies, such as improved

plant varieties and use of

chemical herbicides, which

would increase productivity

and slow deforestation by

(10) reducing demand for new

cropland. Studies have

shown that farmers in

developing countries who

have achieved certain levels

(15) of education, wealth, and

security of land tenure are

more likely to adopt such

technologies. But these

studies have focused on

(20) villages with limited land

that are tied to a market

economy rather than on

the relatively isolated, selfsufficient

communities with

(25) ample land characteristic of

rain-forest regions. A recent

study of the Tawahka people

of the Honduran rain forest

found that farmers with some

(30) formal education were more

likely to adopt improved plant

varieties but less likely to

use chemical herbicides

and that those who spoke

(35) Spanish (the language of

the market economy) were

more likely to adopt both

technologies. Nonland

wealth was also associated

17

(40) with more adoption of both

technologies, but availability

of uncultivated land reduced

the incentive to employ the

productivity-enhancing tech-

(45) nologies. Researchers

also measured land-tenure

security: in Tawahka

society, kinship ties are a

more important indicator of

(50) this than are legal property

rights, so researchers

measured it by a household’s

duration of residence

in its village. They found

(55) that longer residence correlated

with more adoption

of improved plant varieties

but less adoption of

chemical herbicides.



The primary purpose of the passage is to

A. evaluate the likelihood that a particular proposal, if implemented, would

ultimately succeed in achieving its intended result

B. question the assumption that certain technological innovations are the most

effective means of realizing a particular environmental objective

C. discuss the progress of efforts to encourage a particular traditional society to

adopt certain modern agricultural methods

D. present the results of new research suggesting that previous findings concerning

one set of conditions may not be generalizable to another set of conditions

E. weigh the relative importance of three factors in determining whether a particular

strategy will be successful



Q:

According to the passage, the proposal mentioned in line 1 is aimed at preserving rain

forests by encouraging farmers in rain-forest regions to do each of the following

EXCEPT

A. adopt new agricultural technologies

B. grow improved plant varieties

C. decrease their use of chemical herbicides

D. increase their productivity

E. reduce their need to clear new land for cultivation



Q1:



The passage suggests that in the study mentioned in line 27 the method for gathering

information about security of land tenure reflects which of the following pairs of

assumptions about Tawahka society?

A. The security of a household’s land tenure depends on the strength of that

household’s kinship ties, and the duration of a household’s residence in its village

is an indication of the strength of that household’s kinship ties.

B. The ample availability of land makes security of land tenure unimportant, and the

lack of a need for secure land tenure has made the concept of legal property rights

unnecessary.

C. The strength of a household’s kinship ties is a more reliable indicator of that

household’s receptivity to new agricultural technologies than is its quantity of

nonland wealth, and the duration of a household’s residence in its village is a

more reliable indicator of that household’s security of land tenure than is the

strength of its kinship ties.

D. Security of land tenure based on kinship ties tends to make farmers more

receptive to the use of improved plant varieties, and security of land tenure based

on long duration of residence in a village tends to make farmers more receptive to

the use of chemical herbicides.

E. A household is more likely to be receptive to the concept of land tenure based on

legal property rights if it has easy access to uncultivated land, and a household is

more likely to uphold the tradition of land tenure based on kinship ties if it

possesses a significant degree of nonland wealth.

Q4:

The findings of the study mentioned in line 27, if valid for rain-forest regions in general,

suggest that which of the following is an obstacle most likely to be faced by those

wishing to promote rain-forest preservation by implementing the proposal mentioned in

line 1?

A. Lack of legal property rights tends to discourage local farmers from investing the

time and resources required to successfully implement new agricultural

technologies.

B. The ability to evaluate the wider economic ramifications of adopting new

aricultural technologies depends on a relatively high level of formal education.

C. Isolation from the market economy tends to restrict local farmers’ access to new

agricultural technologies that could help them to increase their productivity.

D. Ready availability of uncultivated land tends to decrease local farmers’ incentive

to adopt new agricultural technologies that would reduce their need to clear new

land for cultivation.

E. Traditions of self-sufficiency and reliance on kinship ties tend to diminish local

farmers’ receptivity to new agricultural technologies introduced by people from

outside the local communit
