Zorluk: KolaySentence-Level Transitions

In 1977, oceanographers exploring the Pacific Ocean made a startling discovery: deep-sea hydrothermal vents spewing mineral-rich water. Prior to this expedition, scientists believed that all life on Earth depended on sunlight for energy. [1] Consequently, these vents supported thriving communities of organisms that lived in complete darkness.

Which choice provides the most logical transition between the two sentences?

  1. A
    NO CHANGE
  2. However,Cevap
  3. C
    Similarly,
  4. D
    For example,

Cevap

However,
The transition 'However' is correct because it establishes a clear contrast between the old scientific belief (that all life requires sunlight) and the new discovery (that these vents support life in complete darkness).

Adım Adım Çözüm

1
Analyze the relationship between the two sentences.
The first sentence describes a belief that all life depends on sunlight. The second sentence describes the discovery of life in complete darkness. This represents a contrast between an expectation and a reality.
Understanding the logical connection between the two ideas is necessary to choose the correct transition.
2
Evaluate the transition category needed.
Since the two sentences express contrasting ideas, a contrast transition (like 'however') is required.
A contrast transition signals to the reader that the second sentence contradicts or qualifies the first.
3
Match the transition category to the options.
'However' is the only transition among the choices that signals contrast, while 'Consequently' (cause-effect), 'Similarly' (similarity), and 'For example' (illustration) do not fit.
Selecting the option that matches the identified logical category ensures the sentence is coherent.

Anahtar Kavram

Selecting the transition word that establishes the correct logical relationship between consecutive sentences.
