Zorluk: OrtaTransitions: Contrast and Concession

Axolotls possess an extraordinary ability to regenerate complex body parts, leading scientists to long assume that their cellular mechanisms were entirely distinct from those of mammals. ______ genomic analyses have recently revealed that the key signaling pathways involved in axolotl limb regeneration are also present and active in mammalian genomes, though they remain dormant in humans.

Which choice completes the text with the most logical transition?

  1. A
    Consequently,
  2. However,Cevap
  3. C
    In addition,
  4. D
    Specifically,

Cevap

However,
The correct answer is 'However,' because the first sentence outlines a traditional assumption (that axolotl regeneration mechanisms are completely distinct from mammalian ones) and the second sentence introduces a counter-finding (that they actually share key signaling pathways). A contrast transition is required to logically connect these two ideas.

Adım Adım Çözüm

1
Analyze the relationship between the two sentences.
The first sentence describes a long-held scientific assumption: axolotl regenerative mechanisms are completely different from mammalian ones. The second sentence presents recent genomic evidence showing these pathways are actually shared, which directly contradicts the initial assumption.
Identifying the logical relationship between the sentences is necessary to determine the correct transition category.
2
Determine the required transition type.
Since the second sentence contradicts or presents a counter-argument to the first, a contrast or concession transition is needed.
Matching the identified relationship to a transition type allows us to narrow down the choices.
3
Evaluate the choices based on the transition type.
The word 'however' indicates a contrast relationship. The other choices ('consequently', 'in addition', and 'specifically') represent cause-and-effect, addition, and elaboration relationships, respectively.
Selecting the option that correctly implements the contrast relationship yields the correct answer.
