Difficulty: MediumTransitions: Addition and Similarity

In studies of marine locomotion, researchers have noted that the undulating motion of a bluefin tuna's caudal fin maximizes thrust while minimizing energy expenditure. ______ observations of bigeye thresher sharks reveal that their elongated caudal fins are structurally optimized to achieve a comparable hydrodynamic efficiency during rapid acceleration.

Which choice completes the text with the most logical transition?

  1. Likewise,Answer
  2. B
    Nonetheless,
  3. C
    Additionally, also,
  4. D
    Consequently,

Answer

Likewise,
The transition 'Likewise' is correct because it logically establishes a relationship of similarity between the two observations. The first sentence describes how the bluefin tuna's caudal fin achieves hydrodynamic efficiency, and the second sentence details how the bigeye thresher shark's caudal fin achieves a similar high efficiency. 'Likewise' appropriately connects these parallel cases of hydrodynamic adaptation.

Step-by-Step Solution

1
Analyze the logical relationship between the first and second sentences of the passage.
The first sentence describes how the caudal fin of a bluefin tuna maximizes thrust and minimizes energy (hydrodynamic efficiency). The second sentence states that thresher sharks possess caudal fins optimized to achieve a comparable hydrodynamic efficiency.
Understanding the connection between the two points is necessary to determine the correct logical relationship.
2
Determine the category of transition needed to connect these two sentences.
Since both sentences describe similar biological adaptations for hydrodynamic efficiency in different marine species, a transition indicating similarity or analogy is required.
Identifying the transition category narrows down the choices to those expressing addition or similarity.
3
Evaluate the choices to find the transition that correctly expresses similarity without creating grammatical or stylistic errors.
The transition 'Likewise' correctly expresses similarity. 'Nonetheless' expresses contrast, 'Consequently' expresses cause-and-effect, and 'Additionally, also' is redundant.
Selecting the grammatically sound transition that fits the logical category leads to the correct answer.
