Zorluk: ZorTransitions: Elaboration and Exemplification

Biologists studying the evolutionary history of flight have identified numerous instances of convergent evolution, wherein unrelated organisms independently develop similar physical traits to adapt to aerial environments. __________ both bats and birds evolved wings capable of powered flight, yet their skeletal structures reveal that these appendages adapted from entirely different ancestral limbs.

Which choice completes the text with the most logical transition?

  1. A
    Conversely,
  2. B
    Subsequently,
  3. For example,Cevap
  4. D
    Consequently,

Cevap

The transition 'For example,' is the correct choice because it logically connects the general statement about convergent evolution in the first sentence to the specific instance of bats and birds in the second sentence.
The first sentence introduces the general concept of convergent evolution, where unrelated organisms develop similar traits. The second sentence provides a specific instance of this phenomenon: bats and birds independently developing wings from different ancestral structures. Therefore, an exemplification transition like 'For example' is required to establish the relationship between a general statement and a specific instance.

Adım Adım Çözüm

1
Analyze the relationship between the first and second sentences.
The first sentence introduces the general concept of convergent evolution (unrelated organisms developing similar traits for aerial environments). The second sentence describes a specific case: bats and birds developing wings from different ancestral structures.
Identifying the logical connection between the sentences is necessary to determine the appropriate transition type.
2
Determine the category of transition required.
Since the second sentence provides a specific instance that illustrates the general statement in the first sentence, an exemplification transition is needed.
This narrows down the choices to transition words or phrases that introduce examples or details.
3
Evaluate the choices to find the one that fits the exemplification category.
'For example,' is an exemplification transition that fits perfectly. 'Conversely,' (contrast), 'Subsequently,' (chronology), and 'Consequently,' (cause-and-effect) do not fit the logical relationship.
Selecting the correct transition completes the passage with logical coherence.
