Difficulty: MediumTransitions: Elaboration and Exemplification

Environmental scientists often employ bioremediation strategies that utilize specialized microorganisms to break down pollutants, converting hazardous chemicals into non-toxic byproducts. ________, researchers frequently deploy the marine bacterium *Alcanivorax borkumensis* during ocean oil spill cleanups because it produces unique enzymes that consume hydrocarbons, effectively transforming the contaminants into harmless fatty acids.

Which choice completes the text with the most logical transition?

  1. A
    Subsequently,
  2. Specifically,Answer
  3. C
    Conversely,
  4. D
    Furthermore,

Answer

Specifically,
The correct transition is 'specifically' because it logically introduces a particular example (the marine bacterium *Alcanivorax borkumensis* degrading oil) that illustrates the general statement in the preceding sentence (the use of specialized microorganisms in bioremediation).

Step-by-Step Solution

1
Analyze the relationship between the two sentences.
The first sentence introduces the general concept of bioremediation using microorganisms. The second sentence introduces a specific bacterium and its role in cleaning up oil spills.
Identifying how the ideas connect is necessary to determine the category of transition needed.
2
Determine the appropriate category of transition.
Since the second sentence provides a detailed example of the general concept in the first sentence, an elaboration or exemplification transition is required.
The transition must signal that the second sentence details or illustrates the first.
3
Evaluate the choices to find the transition that fits the category.
The transition 'specifically' signals elaboration, whereas 'conversely' signals contrast, 'furthermore' signals addition, and 'subsequently' signals chronology.
Selecting the option that matches the identified category ensures logical flow.
