Cuttlefish appear to be surprisingly ____at exercising self-control: in a 2021 study conducted by behavioral ecologist Alexandra Schnell, these cephalopods routinely demonstrated restraint by delaying gratification, waiting for a favorite treat instead of instantly devouring a readily available meal.
Which choice completes the text with the most logical and precise word or phrase?
A. manageable
B. awkward
C. imaginative
D. competent
The correct answer and explanation is:
The correct answer is D. competent.
The sentence describes cuttlefish as capable of “exercising self-control” and delaying gratification in order to wait for a favorite treat. This suggests that the cuttlefish exhibit a high level of skill or ability in controlling their impulses. The word “competent” means having the necessary ability, knowledge, or skill to do something successfully. Therefore, it fits the context of the sentence, where cuttlefish are shown to possess the ability to make thoughtful decisions and demonstrate self-control.
Let’s analyze the other options:
- A. manageable: This term refers to something that can be handled or controlled. It does not convey the idea of a skill or capability, which is what the sentence is implying about the cuttlefish’s behavior.
- B. awkward: “Awkward” means something that is clumsy or difficult to manage. This would not be a fitting description of cuttlefish, as the sentence highlights their ability to demonstrate restraint, not awkwardness.
- C. imaginative: “Imaginative” means having creativity or inventiveness. Although cuttlefish might display problem-solving skills, the focus here is on self-control, not creativity. “Imaginative” would not be the most logical choice to complete the sentence.
Thus, competent is the most logical and precise word, as it aligns with the idea that the cuttlefish are effective in exercising self-control.
