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

The Hadejia-Nguru wetlands, situated in the Yobe-Kano basin of northern Nigeria, constitute an ecological zone of international significance. Formed by the inundation of the Hadejia and Jama'are rivers, these wetlands cover approximately 3,500 square kilometres during peak flooding seasons. The ecosystem provides crucial wintering grounds for millions of migratory birds travelling along the West African-Eurasian flyway. Beyond its ecological role, the area supports over 1.5 million people who rely on rice cultivation, recession agriculture, and artisanal fishing. However, upstream dam construction—specifically the Tiga and Challawa Gorge dams—has significantly reduced seasonal river inflow, threatening the wetland's natural hydrological cycle and the livelihoods of surrounding rural communities.

Statement: The Hadejia-Nguru wetlands were artificially created as a direct result of constructing the Tiga and Challawa Gorge dams.

Answer: Answer

Answer

False
The statement is false because the passage explicitly states that the wetlands were formed by the natural overflow of the Hadejia and Jama'are rivers. The Tiga and Challawa Gorge dams are described as upstream structures that reduced water flow, rather than creating the wetlands.

Step-by-Step Solution

1
Analyze the statement's claim about the origin of the Hadejia-Nguru wetlands.
The statement asserts that the wetlands were artificially created by the Tiga and Challawa Gorge dams.
To verify whether the text explicitly corroborates this causal relationship.
2
Locate explicit passage evidence regarding the formation of the wetlands and the role of the dams.
The passage confirms the wetlands were 'Formed by the inundation of the Hadejia and Jama'are rivers' and notes that the dams 'reduced seasonal river inflow'.
Direct fact retrieval reveals the dams threatened and reduced inflow to an already existing natural wetland, contradicting the statement.
