Paragraph 1

Wetlands are unique environments defined by the presence of water, either permanently or seasonally, at or near the surface of the soil. These areas, which include marshes, swamps, and bogs, play an important role in maintaining ecological balance. Covering about 6% of the Earth's surface, wetlands are found on every continent except Antarctica. Their importance goes beyond just variety of life; they provide essential services like water filtration, flood control, and carbon storage. The complex connections of water, soil, and plants in wetlands create a habitat that supports a diverse range of flora and fauna, making them among the most productive environments on the planet.

Factual Information Questions

1. According to paragraph 1, what percentage of the Earth's surface do wetlands cover?
   
   1. 4%
   2. 6%
   3. 8%
   4. 10%

Negative Factual Information Questions

1. The author mentions all of the following as essential services provided by wetlands EXCEPT:
   
   1. Water filtration
   2. Flood control
   3. Soil erosion prevention
   4. Carbon storage

Paragraph 2

The water dynamics of wetlands is a key feature that influences their environmental functions. Water levels in these environments can change due to seasonal shifts, rainfall, and human activities. For example, during heavy rainfall, wetlands can absorb excess water, helping to reduce the risk of flooding in surrounding areas. On the other hand, during dry spells, wetlands can release stored water, maintaining stream flows and supporting aquatic life downstream. This dynamic water management is important for the survival of many species, including migratory birds that rely on wetlands as key stopover points during their long journeys. The ability of wetlands to regulate water flow and quality highlights their importance in both natural and human-altered landscapes.

Inference Questions

1. What can be inferred about the role of wetlands in supporting migratory birds?
   
   1. They provide food sources for migratory birds.
   2. They serve as critical resting points during migration.
   3. They are the primary breeding grounds for migratory birds.
   4. They are less important than other habitats for migratory birds.

Paragraph 3

Despite their ecological importance, wetlands face many threats, mainly from human activities. Urban development, agriculture, and industrialisation have led to the draining and decline of these essential environments. For example, turning wetlands into agricultural land often results in the loss of variety of life and disrupts natural water cycles. Additionally, pollution from agricultural runoff and industrial waste can severely impact water quality, harming wetland habitats. The loss of wetlands not only reduces biodiversity but also decreases the ecosystem services they provide, such as flood protection and water purification. So, the ongoing destruction of wetlands presents an important challenge for conservation efforts, requiring immediate and effective action.

Rhetorical Purpose Questions

1. Why does the author mention the impact of pollution from agricultural runoff in paragraph 3?
   
   1. To illustrate the benefits of wetlands
   2. To highlight the threats wetlands face from human activities
   3. To discuss the economic advantages of agriculture
   4. To suggest alternative land uses for wetlands

Paragraph 4

Conservation strategies for wetlands have changed over the years, reflecting a growing awareness of their importance. Various international agreements, such as the Ramsar Convention on Wetlands, aim to support the sustainable use and conservation of these environments. National and local governments have also implemented policies to protect wetlands through the creation of protected areas and restoration projects. For example, wetland restoration projects often involve re-establishing natural water patterns and reintroducing native plant species. These efforts not only help restore the ecological health of wetlands but also enhance their ability to provide essential services. However, successful conservation requires cooperation among parties involved, including government agencies, non-profit organisations, and local communities, to ensure that diverse interests are represented and addressed.

Vocabulary Questions

1. The word "restoration" in paragraph 4 is closest in meaning to:
   
   1. Improvement
   2. Recovery
   3. Maintenance
   4. Replacement

Paragraph 5

The role of wetlands in climate change reduction is a developing area of research that highlights their global importance. Wetlands act as carbon sinks, capturing large amounts of carbon dioxide from the atmosphere. This process occurs through the buildup of organic matter in waterlogged soils, which slows down decay rates. As a result, wetlands can store carbon for long periods, helping to lessen the impacts of climate change. However, the decline of wetlands can release stored carbon back into the atmosphere, worsening global warming. So, protecting and restoring wetlands is crucial not only for biodiversity but also for climate resilience. The awareness of wetlands as essential parts of climate change strategies is gaining support among decision-makers and conservationists, prompting calls for combined approaches that consider both environmental and economic factors.

Sentence Simplification Questions

1. Which of the sentences below best expresses the essential information in the following text in paragraph 5?
   

   "Wetlands act as carbon sinks, capturing large amounts of carbon dioxide from the atmosphere."

   1. Wetlands are important for capturing carbon dioxide.
   2. Wetlands are the main source of carbon dioxide.
   3. Wetlands do not affect carbon levels in the atmosphere.
   4. Wetlands only capture carbon during certain seasons.

Paragraph 6

In conclusion, wetlands are essential environments that provide a wide range of ecological, economic, and social benefits. Their ability to regulate water flow, filter pollutants, and capture carbon underscores their importance in both local and global contexts. However, the ongoing threats from human activities require urgent conservation efforts to protect these vital habitats. As awareness of the importance of wetlands continues to grow, it is imperative that cooperative strategies are developed to ensure their preservation for future generations. The complex balance of life within wetlands serves as a reminder of the connection between ecosystems and the need for sustainable management practices that respect and protect these invaluable resources. Future research should focus on understanding the long-term impacts of climate change on wetland environments and exploring new solutions for their conservation and restoration.
