1. The factors that have contributed most to water shortages in cities such as Cape Town are B. drought conditions and D. rapid population growth.
2. The strategy that will most decrease the number of people sickened by water-borne diseases is D. better sanitation systems.
3. The statement that describes a struggle over water rights between Egypt and Ethiopia over the Nile River is C. Both countries want more control over the flow of the river for irrigation and electricity production.
1. To determine the factors that have contributed most to water shortages in cities such as Cape Town, we need to carefully evaluate each option:
A. Lack of wastewater treatment: Wastewater treatment plays a crucial role in recycling and reusing water. If there is a lack of proper treatment facilities, it can lead to water wastage and scarcity. However, it may not be one of the primary factors contributing to water shortages.
B. Drought conditions: Drought is a significant factor that often leads to water shortages in cities. It occurs when there is an extended period of below-average precipitation. Drought conditions can significantly reduce water availability.
C. Use of recycled water: The use of recycled water, also known as reclaimed water, can help alleviate water scarcity to some extent. By treating wastewater and reusing it for non-potable purposes like irrigation or industrial processes, cities can reduce pressure on freshwater sources. However, it may not be one of the primary factors contributing to water shortages.
D. Rapid population growth: The rate at which a city's population grows can strain its water resources. As more people require water for various purposes, the demand increases, potentially leading to water shortages.
E. Increase in water pollution: Water pollution can have detrimental effects on water availability. Contamination of water sources, such as rivers or aquifers, can render the water unusable or require extensive treatment processes. However, it may not be one of the primary factors contributing to water shortages.
Considering all the options, the two factors that have likely contributed most to water shortages in cities like Cape Town are:
B. Drought conditions
D. Rapid population growth
2. To determine the strategy that will most decrease the number of people sickened by water-borne diseases, let's analyze the options:
A. Increased use of solar power: While transitioning to renewable energy sources, such as solar power, can have several environmental benefits, it may not directly impact the number of people sickened by water-borne diseases.
B. Improved agriculture: Enhancing agricultural practices can indirectly contribute to reducing water-borne diseases. Implementing proper irrigation methods, reducing pesticide and fertilizer runoff, and promoting sustainable farming practices can help minimize water pollution, thereby improving water quality and reducing the risk of water-borne diseases. However, it may not be the most effective strategy listed.
C. Increased use of fungicides: Fungicides are chemicals used to kill or inhibit the growth of fungi. However, water-borne diseases are generally caused by bacteria, viruses, or parasites, not fungi. Therefore, increased use of fungicides may not be an effective strategy for decreasing the number of people sickened by water-borne diseases.
D. Better sanitation systems: Improving sanitation systems is crucial for minimizing water-borne diseases. Effective sewage treatment, proper waste management, and access to clean, safe drinking water are essential in reducing contamination and preventing the transmission of water-related illnesses. Therefore, the most effective strategy among the options provided is:
D. Better sanitation systems
3. To understand the struggle over water rights between Egypt and Ethiopia over the Nile River, let's evaluate each statement:
A. Each country wants the other country to sign the Nile Waters Agreements: This statement does not accurately capture the ongoing water rights struggle between Egypt and Ethiopia. The Nile Waters Agreements refer to agreements that have been signed by multiple countries, including Egypt, but not by Ethiopia. Thus, both countries do not want each other to sign these agreements.
B. Both countries want to ensure that the flow of the Nile is steady in all of the countries it passes through: This statement does not accurately reflect the struggle between Egypt and Ethiopia. While both countries have concerns about the Nile's flow, the focus of their dispute revolves more around specific upstream projects impacting water availability downstream rather than ensuring a steady flow for all countries.
C. Both countries want more control over the flow of the river for irrigation and electricity production: This statement accurately depicts the struggle over water rights between Egypt and Ethiopia. Both countries have economic interests dependent on the Nile's waters, particularly for agriculture and electricity generation. They desire control over the water flow to meet their respective needs, leading to tensions and negotiations.
D. Each country wants the other country to be responsible for wastewater treatment along the river: This statement does not accurately represent the struggle between Egypt and Ethiopia. The dispute primarily revolves around water rights and control of the Nile's flow, rather than wastewater treatment responsibilities.
Thus, the statement that describes the struggle over water rights between Egypt and Ethiopia over the Nile River is:
C. Both countries want more control over the flow of the river for irrigation and electricity production.
