Zorluk: OrtaTransitions: Chronology and Sequence

In 1912, meteorologist Alfred Wegener proposed the theory of continental drift, suggesting that Earth's continents were once joined in a single landmass. Because he could not identify a mechanism for how the continents moved, his ideas were widely dismissed. ______ in the 1950s, researcher Marie Tharp mapped the ocean floor using sonar data, revealing the Mid-Atlantic Ridge and providing the crucial evidence of seafloor spreading. This discovery validated Wegener's concepts, cementing the modern theory of plate tectonics.

Which choice completes the text with the most logical transition?

  1. A
    Conversely,
  2. B
    Previously,
  3. Subsequently,Cevap
  4. D
    Specifically,

Cevap

Subsequently,
The passage describes two chronological events: Alfred Wegener's proposal of continental drift in 1912, followed by Marie Tharp mapping the ocean floor in the 1950s. The transition word 'Subsequently' correctly signals that Tharp's work happened after Wegener's proposal.

Adım Adım Çözüm

1
Analyze the relationship between the ideas in the passage.
The first part of the passage describes Alfred Wegener's proposal in 1912. The second part describes Marie Tharp mapping the ocean floor in the 1950s.
Identifying the chronological relationship between the events is necessary to choose the correct transition word.
2
Determine the temporal order of these events.
The event in the second sentence (1950s) occurs after the event in the first sentence (1912).
This determines that a transition word indicating a subsequent time or chronological progression is needed.
3
Evaluate the choices to find the one that matches this relationship.
'Subsequently' correctly indicates a subsequent event in a sequence.
Selecting the transition that matches the chronological order of the text ensures logical flow.
