Sentence Elimination- Wetlands

  1. Coastal wetlands can even grow in height as sea level rises, protecting communities further inland.
  2. Salt marshes and mangrove forests store flood waters and protect coasts from hurricanes and storms.
  3. Continuously removing and storing atmospheric carbon, wetlands act as 'carbon sinks' that help mitigate climate change.
  4. In addition, wetlands make ecosystems and human communities more resilient in the face of climate change.

 

  • Correct Answer
    Choice C

Detailed Solution

Option A states that coastal wetlands help protect communities inland by growing in height as the sea level rises. Option B, too, talks of wetlands such as marshes and mangrove forests. These help to protect coasts from hurricanes and storms by storing flood waters. The common thread between A and B is that wetlands help to protect coastal communities from hurricanes, storms and sea level rise.

Options C and D talk of climate change. C states that wetlands help to mitigate climate change acting as carbon sinks, while D explains that wetlands make ecosystems and human communities more resilient in the face of climate change.

Let us look for an idea that overlaps AB and CD.

Like A and B, option D talks of the impact of wetlands on human communities. D states that wetlands make these communities more resilient in the face of climate change—an idea that is substantiated by examples in A and B. DBA makes a cogent paragraph.

On the other hand, C talks of how wetlands help to mitigate or reduce the impact of climate change. This is a slightly different idea. So, C is the sentence to be eliminated.

Correct Answer: Choice (C)
