A factual passage is composed of information about a particular subject in a clear, straightforward, and direct manner. These passages focus completely on details or facts. It gives a comprehensive view on the information provided and may include instructions to do something, a report about new findings, or a description of something. Most often, it also requires the students to study and interpret dues, decipher them, and answer the question given. Example: Head the passage given be Low.


(1) The Sahara sets a standard for dry land, It's the worlds largest desert. Relative humrdrty can drop into the low single digits. There are places where it rains only about once a century. There are people who reach the end of their lives without ever seeing water come from the sky. Yet beneath the Sahara are vast aquifers of fresh warer, enough liquid to fill a small sea. it is fossil water, a treasure laid down in prehistoric times, some of it possibly a million years old. Just years ago, the Sahara was quite a different place, it was green. Prehistoric rock art in the Sahara shows something surprising: hippopotamuses, who need water year round.


(2) We don't have much evidence of a tropical paradise out there, bu t we hod something perfectly livable, says Jennifer Smith, a geologist at Washington University in St Louis. At times when the Northern Hemisphere tilts sharply towards the sun and die planet makes its closest approach, the increased blast of sunlight during the North's summer months can cause the African monsoon fwhrch currently occurs between the Equator and roughly 17*N latitude,) to shift to the North as it did 10,000 years ago, inundating North Africa.


(3) Around 5,000 years ago, the monsoon shifted dramatically southward again. The prehistoric inhabitants of the Sahara discovered that their relatively green surroundings were undergoing something worse than a drought (and perhaps they migrated towards the Nile Walley, where Egyptian culture began to flourish at around the same time).


(4) As the land dried out and vegetation decreased, the soil, lost its ability to hold water when it rair>ed. Fev/er clouds formed from evaporation. When it rained1, the water washed away and evaporated quickly. There was a kind of runaway drying effect. Around 4,000 years ago, the Sahara became what it is today. No one knows how human-driven climate change may alter the Sahara in the future its something scientists can ponder while sipping bottled fossil water pumped from the underground. "Its the best water in Egypt, "Robert Giegengack a University of Pennsylvania geologist, said — clean, refreshing mineral water. If you want to drink something good, try the ancient buried treasure of the Sahara.


Q. Which of the following statements about how the rich underground reserves help Sub- Saharan Africa is correct?

  • a)
    They helped by providing rainfall

  • b)
    They helped through electricity generation

  • c)
    They helped by boosting its economy

  • d)
    They helped by using hydropower to create electricity 

Correct answer is option 'C'. Can you explain this answer?
Verified Answer
A factual passage is composed of information about a particular subjec...
Explanation: The passage describes the vast aquifers of fresh water beneath the Sahara as a valuable resource, referring to it as "fossil water" and a "treasure." Although the passage does not explicitly mention the economic benefits, it implies that access to such a vital resource can significantly impact the region's economy by providing clean, refreshing mineral water. This can support agriculture, industry, and daily life, ultimately boosting the economy.
The other options are incorrect because the passage does not mention rainfall, electricity generation, or hydropower as benefits provided by the underground water reserves.

Understanding the Role of Underground Reserves in Sub-Saharan Africa
The rich underground water reserves in regions like the Sahara have significant implications for the economy and livelihood of Sub-Saharan Africa. Here's how these reserves contribute:
Economic Boost
- Agricultural Support: The availability of underground water allows for irrigation in arid regions, enhancing agricultural productivity. This leads to better food security and income for farmers.
- Job Creation: Increased agricultural output and the development of water-intensive industries create jobs, reducing unemployment rates in the region.
- Trade Enhancement: Agriculture supported by these water reserves can lead to surplus production, which can be traded, further boosting the local economy.
Infrastructure Development
- Access to Clean Water: Underground aquifers provide a source of clean drinking water, improving public health and reducing water-borne diseases that can hinder economic activity.
- Investment Opportunities: The presence of water resources attracts investments in various sectors, including agriculture and tourism, which can stimulate economic growth.
Community Resilience
- Sustainable Practices: Communities can implement sustainable water management practices, ensuring that the underground reserves are used wisely for long-term benefits.
- Climate Adaptation: Access to underground water aids in adapting to climate changes, allowing communities to maintain agricultural practices even during periods of low rainfall.
In conclusion, option 'C' is correct because the underground water reserves in Sub-Saharan Africa provide crucial support for economic growth, enhancing agricultural productivity, creating jobs, and improving overall community resilience.
