Zorluk: KolayExclusion Questions (EXCEPT/LEAST/NOT)

Mangrove forests are vital coastal ecosystems that provide a multitude of ecological and economic benefits. One of their most recognized functions is coastal protection; their dense, tangled root systems act as a natural barrier, dissipating wave energy and reducing the impact of storm surges on inland communities. Furthermore, mangroves serve as crucial nursery habitats for numerous marine species, offering juvenile fish and crustaceans shelter from predators before they migrate to open ocean environments. In addition to these physical benefits, mangroves are highly efficient carbon sinks. They sequester significant amounts of carbon dioxide from the atmosphere, storing it in their biomass and the underlying waterlogged soil for millennia. However, despite these benefits, mangrove ecosystems are increasingly threatened by aquaculture expansion, particularly shrimp farming, which requires the clearing of large tracts of coastal land.

According to the passage, the ecological and physical benefits of mangrove forests include all of the following EXCEPT:

  1. A
    acting as a natural barrier against coastal storm surges
  2. B
    providing shelter from predators for juvenile marine species
  3. supplying the primary diet for mature open-ocean predatorsCevap
  4. D
    storing atmospheric carbon dioxide in their soil and biomass
  5. E
    dissipating the energy of incoming waves

Cevap

The option stating that mangroves supply the primary diet for mature open-ocean predators.
The correct answer is the only statement not supported by the passage. The text discusses mangroves providing shelter for juvenile marine species before they migrate, but it never asserts that mangroves provide the primary diet for mature open-ocean predators.

Adım Adım Çözüm

1
Analyze the question stem to identify the task.
The capitalized word 'EXCEPT' indicates that the correct answer will be the only option NOT listed as a benefit in the passage.
Recognizing the exclusion indicator is critical for selecting the right evaluation strategy.
2
Scan the passage for explicitly mentioned benefits and functions of mangrove forests.
Identified benefits include: acting as a natural barrier, dissipating wave energy, reducing storm surge impact, offering shelter for juvenile marine species, and storing carbon dioxide.
Creating a mental or written list of supported details allows for rapid elimination of wrong answers.
3
Evaluate each answer choice against the identified text details.
Four of the choices match the listed benefits. The statement about supplying the primary diet for mature open-ocean predators is completely absent from the text.
Eliminating supported statements reveals the single unsupported, unmentioned claim.
