Zorluk: OrtaTransitions: Contrast and Concession

In the study of art history, researchers long believed that the vibrant blue pigment used in ancient Maya murals, known as Maya Blue, was highly susceptible to biodegradation over centuries due to its organic dye component, indigo. ________, recent chemical analysis has revealed that the encapsulation of indigo molecules within the crystalline channels of the clay palygorskite creates a highly stable organo-clay complex that is impervious to acids, alkalis, and microbial attack.

Which choice completes the passage with the most logical transition?

  1. A
    Subsequently,
  2. B
    For instance,
  3. However,Cevap
  4. D
    Furthermore,

Cevap

However,
The correct answer is the option stating 'However,'. The first sentence outlines a long-held belief that Maya Blue pigment is vulnerable to biodegradation. The second sentence presents recent chemical findings showing that it is actually highly stable and resistant to damage. This transition of ideas is a direct contrast, which is correctly signaled by 'However,'.

Adım Adım Çözüm

1
Analyze the relationship between the two parts of the passage.
The first sentence notes a historical belief that Maya Blue pigment is fragile and susceptible to biodegradation. The second sentence introduces modern scientific evidence showing that the pigment is extremely stable and resistant to decay.
Understanding the logical connection between the ideas is necessary to determine the correct transition.
2
Determine the type of transition required.
Since the passage moves from a belief of susceptibility to a finding of high durability, a contrast or concession transition is needed to connect these opposing ideas.
This establishes the logical relation that the correct transition must signal.
3
Evaluate the choices based on the identified relationship.
The option stating 'However,' is a contrast transition and fits the context. The option stating 'Subsequently,' signals chronology; the option stating 'For instance,' signals exemplification; and the option stating 'Furthermore,' signals addition. None of these other options express contrast.
Only one option correctly aligns with the contrast relationship established in the passage.
