Question

Difficulty: MediumIdentification of Main Idea and Supporting Details

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

For decades, pastoralist communities in Kenya’s arid northern regions faced severe economic losses due to the rapid spoilage of raw camel milk during transport to urban centers. Traditional gourds offered minimal thermal protection against intense equatorial heat, resulting in up to forty percent of daily yields turning sour before reaching commercial buyers. In response, local women’s cooperatives in Garissa recently pioneered solar-powered chilling hubs equipped with insulated stainless-steel storage containers. This decentralized cold-chain infrastructure enables herdsmen to deposit fresh milk within two hours of milking, thereby preserving its nutritional quality and maintaining low bacterial counts. Consequently, smallholder camel farmers have stabilized their household income, expanded their commercial market distribution into major urban centers like Nairobi, and significantly enhanced regional food security through sustainable trade.

Statement: The central thesis of the passage is that traditional gourds fail to provide adequate thermal protection for camel milk during long-distance transport.

Answer: Answer

Answer

The statement is FALSE. The claim highlights a supporting detail regarding the cause of spoilage rather than encapsulating the main idea of the passage.
The statement is false because the thermal failure of traditional gourds is merely a supporting detail outlining the historical background. The true main idea encompasses the deployment of solar-powered chilling hubs and the resulting economic stabilization for pastoralist communities.

Step-by-Step Solution

1
Analyze the passage structure and overall narrative arc.
The passage moves from presenting an initial challenge (spoilage of camel milk in traditional gourds) to detailing a technological solution (solar-powered chilling hubs) and concluding with its positive socio-economic impacts.
Understanding the passage structure is essential for separating background details from the main thesis.
2
Evaluate the statement's scope against the main message of the text.
The statement isolates the failure of traditional gourds as the main focus of the text.
A main idea must reflect the primary outcome and resolution of the text rather than a single introductory premise.
3
Differentiate between a supporting detail and the primary thesis.
Because the text centers on how solar chilling infrastructure transformed camel dairy distribution and improved pastoralist livelihoods, the inefficiency of traditional gourds is merely a supporting detail.
Confusing a supporting fact with the central point is a common comprehension error.
