Zorluk: KolayTransitions: Contrast and Concession

Neptune's moon Triton is one of the coldest objects in our solar system, with surface temperatures hovering around a frigid minus 390 degrees Fahrenheit. Because of this extreme cold, scientists once expected Triton to be a completely dormant, ice-locked world. ______ data from the Voyager 2 spacecraft revealed that Triton exhibits active cryovolcanism, spewing nitrogen gas and dust plumes miles into its thin atmosphere.

Which choice completes the text with the most logical transition?

  1. A
    Therefore,
  2. B
    Moreover,
  3. However,Cevap
  4. D
    Specifically,

Cevap

However,
The correct transition is 'However' because it logically signals a contrast between the expectation that Triton is a dormant, ice-locked world and the actual discovery of active cryovolcanism.

Adım Adım Çözüm

1
Analyze the relationship between the two parts of the text.
The first part of the text states that Triton was expected to be a completely dormant, ice-locked world due to its extreme cold. The second part presents findings from Voyager 2 showing that Triton actually exhibits active geological activity (cryovolcanism).
Understanding the logical connection between the ideas is necessary to select the correct transition.
2
Determine the type of transition required.
A contrast transition is needed to link the expectation of a dormant world with the reality of active volcanism.
Since the two ideas present opposing information, a transition signaling contrast or concession is appropriate.
3
Evaluate the choices to find the contrast transition.
The transition 'However' indicates a contrast relationship, whereas 'Therefore' indicates cause/effect, 'Moreover' indicates addition, and 'Specifically' indicates elaboration.
Only 'However' logically fits the context of showing a contrast between expectations and observations.
