Difficulty: HardTransitions: Addition and Similarity

In the early 1990s, art restorers began utilizing laser ablation to clean fragile marble sculptures, a technique that vaporizes surface contaminants without damaging the underlying stone. This method offered unprecedented precision, allowing conservators to target micro-layers of soot that traditional chemical solvents could not safely remove. _______ the laser's thermal energy could be carefully calibrated to accommodate varying levels of stone degradation, ensuring that even structurally compromised sections of a sculpture remained undisturbed during the cleaning process.

Which choice completes the passage with the most logical transition?

  1. A
    Conversely,
  2. B
    Subsequently,
  3. Furthermore,Answer
  4. D
    Additionally, also,

Answer

Furthermore,
The correct answer is 'Furthermore,'. The passage describes two distinct advantages of using laser ablation for cleaning fragile marble sculptures: its high precision in targeting soot layers and its calibratable thermal energy that prevents damage to degraded stone. The transition 'Furthermore' logically signals that the second point is an additional benefit building upon the first.

Step-by-Step Solution

1
Analyze the relationship between the sentence before the blank and the sentence containing the blank.
The sentence before the blank describes one benefit of laser ablation (precision in removing soot), while the sentence with the blank describes another benefit (calibratable thermal energy that protects degraded stone).
Understanding how the two ideas connect is necessary to choose the correct transition.
2
Identify the type of logical relationship needed.
An addition relationship is needed because the second benefit builds upon and adds to the first benefit.
Selecting the correct relationship category helps narrow down transition options.
3
Evaluate the choices and select the one that correctly and concisely establishes this relationship.
The word 'Furthermore' is a standard addition transition that fits the context perfectly and is grammatically correct.
Choosing the best option requires matching the identified relationship to a grammatically correct and appropriate transition.
