What is 'virtual water'?
- A.
Wastewater generated from domestic activities
- B.
The volume of water used in the production of goods and services
- C.
Water used for irrigation
Correct Answer
B. The volume of water used in the production of goods and servicesExplanation
Virtual water refers to the volume of water that is used in the production of goods and services. It takes into account the amount of water required throughout the entire production process, including the water used to grow crops or raise livestock, as well as the water used in manufacturing and processing. This concept helps to quantify the indirect water footprint of products and understand the water resources embedded in trade and consumption patterns.Rate this question:

'Virtual water' is also known as...
- A.
Freshwater
- B.
Recycled water
- C.
Embedded water
Correct Answer
C. Embedded waterExplanation
'Virtual water' refers to the amount of water that is used to produce a product or service. It includes both the direct water used in the production process and the indirect water used in the production of the inputs. The term 'embedded water' is used to describe this concept, as it represents the water that is embedded or hidden within a product. It helps us understand the water footprint of different products and the impact they have on water resources.Rate this question:

Which type of meat requires the largest amount of water for production per kilogram?
- A.
Pork
- B.
Chicken
- C.
Beef
- D.
Sheep
Correct Answer
C. BeefExplanation
Beef requires the largest amount of water for production per kilogram compared to pork, chicken, and sheep. This is because beef production involves various stages that require significant water usage, such as providing water for the cattle, irrigating the crops they consume, and processing the meat. Additionally, beef cattle typically have a longer lifespan and consume more feed compared to other animals, resulting in a higher overall water footprint for beef production.Rate this question:

The amount of virtual water consumed CANNOT be decreased by reducing the wastage of food.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Reducing the wastage of food can actually decrease the amount of virtual water consumed. Virtual water refers to the water used in the production, processing, and transportation of food. By reducing food wastage, we can minimize the amount of water that goes into producing the wasted food, thus decreasing the overall virtual water consumption. Therefore, the statement is false.Rate this question:

It requires ___ litres of water to produce one kilogram of potatoes.
Correct Answer
900 litresExplanation
The given answer states that it requires 900 litres of water to produce one kilogram of potatoes. This indicates that a significant amount of water is needed for potato production. Potatoes are a water-intensive crop, requiring irrigation throughout their growth cycle. Water is essential for their growth, development, and tuber formation. The high water requirement is due to factors such as evaporation, transpiration, and the need to maintain soil moisture levels. Therefore, 900 litres of water is necessary to produce one kilogram of potatoes.Rate this question:

To produce one apple (100g) requires less water than producing one orange (100g).
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement is false because producing one apple actually requires more water than producing one orange. This is because apple trees require more water throughout their growing season compared to orange trees. Additionally, apple trees have a longer lifespan and require more irrigation, resulting in higher water consumption. Therefore, the statement is incorrect.Rate this question:

Which one of the following products costs the least amount of water to produce?
- A.
A glass of beer - 250ml
- B.
A glass of wine - 250ml
- C.
A cup of tea - 250ml
Correct Answer
C. A cup of tea - 250mlExplanation
The correct answer is a cup of tea - 250ml. Tea is made by steeping tea leaves in hot water, which requires a relatively small amount of water compared to the production processes of beer and wine. Beer is made by fermenting grains, which involves multiple stages and requires a significant amount of water for cleaning and brewing. Wine production involves crushing grapes, fermenting the juice, and aging, which also requires a substantial amount of water. Therefore, compared to beer and wine, a cup of tea requires the least amount of water to produce.Rate this question:
