Meaning: 'Undermine' means to weaken or damage something gradually, often in a subtle way, which in this context refers to diminishing one's confidence.

Wrong options:

• navigate: Navigate means to find one's way through a situation, which does not fit the context of negatively affecting confidence.
• illuminate: Illuminate means to clarify or make something clear, which is the opposite of what imposter syndrome does to confidence.
• fertilize: Fertilize refers to enriching soil or making something more productive, which does not relate to the context of confidence being negatively impacted.

Correct answer: some

Explanation: The word 'some' is appropriate here as it indicates an unspecified but limited number of adults, which fits the context of the statement about the prevalence of imposter syndrome. It is grammatically correct and contextually relevant, as it suggests that not all adults experience this phenomenon.

Meaning: 'Some' refers to an unspecified amount or number, indicating that a portion of adults experience imposter syndrome at various points in their lives.

Wrong options:

• such: Such is used to refer to something previously mentioned, which does not fit the context of quantifying adults experiencing imposter syndrome.
• every: Every implies all individuals without exception, which contradicts the idea that only a portion experiences imposter syndrome.
• all: All suggests totality, which is inaccurate in this context as it does not apply to every adult.

Correct answer: competitive

Explanation: The word 'competitive' fits grammatically as an adjective describing environments that foster pressure and expectations. Contextually, it aligns with the idea that competitive settings can exacerbate feelings of inadequacy associated with imposter syndrome.

Meaning: 'Competitive' refers to an environment where individuals strive against each other, often leading to heightened pressure and expectations.

Wrong options:

• deluded: Deluded means having false beliefs, which does not accurately describe the nature of environments affecting imposter syndrome.
• penitent: Penitent refers to feeling regret for one's sins or mistakes, which is unrelated to the context of competitive environments.
• innate: Innate means existing from birth, which does not fit the context of describing external environments that influence behavior.

Correct answer: attribute

Explanation: The word 'attribute' is a verb that means to regard something as being caused by someone or something. It fits grammatically and contextually, as it describes how individuals with imposter syndrome explain their successes.

Meaning: 'Attribute' means to assign a cause or source to something, in this case, attributing accomplishments to external factors rather than personal abilities.

Wrong options:

• trace: Trace means to follow or discover the course of something, which does not fit the context of explaining accomplishments.
• apply: Apply means to put something into operation, which does not relate to the context of explaining or attributing success.
• credit: Credit means to acknowledge someone for something, which is not the same as attributing accomplishments to external factors.

Correct answer: acknowledging

Explanation: The word 'acknowledging' fits grammatically as a gerund that serves as the subject of the action to overcome imposter syndrome. Contextually, it aligns with the idea of recognizing one's own expertise and achievements as a step towards overcoming feelings of inadequacy.

Meaning: 'Acknowledging' means recognizing or admitting the existence or truth of something, in this case, one's own skills and accomplishments.

Wrong options:

• excusing: Excusing means to justify or overlook something, which does not contribute to overcoming imposter syndrome.
• craving: Craving refers to a strong desire for something, which is unrelated to the process of overcoming feelings of fraudulence.
• weaving: Weaving means to create something by interlacing materials, which does not fit the context of recognizing one's achievements.
