Read the passage below carefully and evaluate the statement that follows.

Passage:
In the dry, rugged highlands of Konso in southern Ethiopia, generations of farmers built an intricate system of stone-walled terraces to trap scarce rainfall and prevent topsoil erosion along steep hillsides. During the late twentieth century, state-sponsored modern agricultural extension programs heavily encouraged replacing these traditional stone bunds with uniform chemical-intensive monoculture. However, the unexpected intensification of erratic weather patterns over the past decade triggered severe landslides and widespread crop failures across the modernized plots, whereas the few remaining terraced farms maintained structural stability and modest yields. Recognizing this resilience, local agricultural cooperatives recently began restoring the neglected stone terraces while reintroducing indigenous drought-hardy sorghum strains. Although initial labor investments for constructing and repairing stone retaining walls are notoriously high, participating households have already recorded lower input costs due to reduced reliance on imported synthetic fertilizers. Moreover, the deep root systems of traditional sorghum cultivars have helped stabilize the terraced soil beds during intense downpours. Consequently, neighboring communities are increasingly abandoning modern monocultural techniques in favor of integrated indigenous soil conservation practices.

Statement:
The resurgence of traditional Konso terracing is primarily driven by its long-term cost-efficiency and ecological adaptability compared to modern monocultural farming.

Cevabı ve açıklamayı göster

Cevap: True

Cevap

True
The statement is logically sound because the text demonstrates that traditional terracing outperforms modern monoculture in environmental stability during extreme weather and reduces financial expenditure on artificial inputs.

Adım Adım Çözüm

1
Identify key evidence regarding ecological performance in the passage.
The text notes that modern monoculture plots suffered landslides and crop failures under erratic weather, while terraced farms retained structural stability and yields.
This establishes the ecological adaptability of the traditional terracing system.
2
Analyze economic input indicators mentioned in the text.
Households recorded lower overall input costs because traditional systems reduced reliance on expensive imported synthetic fertilizers.
This demonstrates long-term cost-efficiency despite high initial labor for wall repairs.
3
Synthesize the findings to evaluate the statement.
Combined evidence confirms that both ecological resilience and economic savings motivate the shift away from modern monoculture.
The statement logically captures the core deductive conclusion supported by the text.

Read the passage below carefully and answer the question that follows:

In the savanna belt of northern Ghana, women's shea cooperatives have traditionally relied on solar-drying harvested nuts on open concrete mats before mechanical extraction. Recently, unseasonal rainfall during the early harvest months forced several federations to adopt biomass-fueled hot-air dryers. While this technological shift halved processing times and protected the nuts from mould infestation during wet spells, it significantly increased operational costs due to the rising price of sustainably sourced firewood. Surprisingly, premium international cosmetics buyers began offering higher purchase contracts to these specific cooperatives. This commercial advantage arose not from the faster turnaround time, but because the controlled thermal environment of the biomass dryers consistently yielded unfermented kernels with lower free fatty acid levels—a key quality metric for luxury skincare formulations. Consequently, nearby independent processors who lacked capital for mechanical dryers began renting off-peak shift hours from the cooperatives, turning the drying facilities into a vital secondary revenue stream for the women.

Based on the passage, what can be logically inferred about the international cosmetics buyers' decision to offer higher contracts?

Cevabı ve açıklamayı göster

Cevap: They prioritized the superior chemical purity of the processed kernels over the reduced processing duration.

Cevap

The international buyers offered higher purchase contracts because they prioritized the improved chemical quality (lower free fatty acid levels) of the kernels over the speed of processing.
The text directly links the premium purchase contracts to the low free fatty acid levels achieved through controlled drying, while explicitly ruling out processing speed as the driver of this commercial benefit. Therefore, it is logically deduced that buyers valued product quality parameters above time savings.

Adım Adım Çözüm

1
Analyze the passage to locate the cause of the premium contracts offered by international buyers.
The text notes that international buyers offered higher purchase contracts to cooperatives using biomass dryers.
Identifying the target evidence line is necessary to deduce the buyers' underlying rationale.
2
Synthesize the contrast presented regarding processing speed versus product quality.
The passage explicitly clarifies that the commercial advantage 'arose not from the faster turnaround time, but because... dryers consistently yielded unfermented kernels with lower free fatty acid levels'.
Distinguishing between what the text rules out (speed) and what it highlights (chemical quality) isolates the valid deduction.
3
Match the synthesized textual evidence with the correct inference option.
The correct option accurately reflects that buyers valued kernel quality metrics over turnaround efficiency.
Ensures logical alignment between textual deduction and option meaning.
