Meaning: 'Committed' means being dedicated to a cause or activity, showing a strong willingness to support and engage in change efforts.

Wrong options:

• transmitted: Transmitted means to send or convey something, which does not fit the context of a leader's personal dedication to change.
• admitted: Admitted implies acknowledging something, which does not convey the proactive engagement required in this context.
• compromised: Compromised suggests a weakening or settling of standards, which contradicts the idea of a leader being fully dedicated to change.

Correct answer: however

Explanation: The word 'however' serves as a discourse marker that introduces a contrast or exception, fitting well in the context of emphasizing the importance of actions over mere words. It connects the previous statement about public actions to the subsequent emphasis on significant actions.

Meaning: 'However' means 'nevertheless' or 'on the other hand,' indicating a contrast to what was previously mentioned.

Wrong options:

• wherever: Wherever indicates a location, which does not fit the context of contrasting actions and their significance.
• whereas: Whereas is used to compare two different things, but it does not convey the intended contrast in this context.
• whenever: Whenever refers to time, which does not align with the need for a contrasting statement about actions.

Correct answer: heart

Explanation: The word 'heart' fits grammatically as a noun that signifies the core or essence of one's beliefs and values. In this context, it indicates that the leader is genuinely internalizing and valuing their own ideas, which is essential for modeling change.

Meaning: 'Heart' in this context means to take something seriously or to internalize it, reflecting a deep commitment to one's own principles.

Wrong options:

• change: Change is a noun that does not fit the context of internalizing ideas; it does not convey the personal connection implied here.
• date: Date refers to a specific time and does not relate to the concept of internalizing or valuing ideas.
• use: Use implies application but lacks the emotional depth and personal connection that 'heart' conveys.

Correct answer: jumped

Explanation: The word 'jumped' fits grammatically as a verb that indicates taking immediate action. In this context, it conveys the proactive nature of Robert Iger's involvement in providing hands-on help, aligning with the theme of commitment to change.

Meaning: 'Jumped' means to take action quickly or enthusiastically, suggesting that Iger actively engaged in the process of innovation.

Wrong options:

• bumped: Bumped implies a collision or accidental contact, which does not convey the intended proactive involvement in change.
• eradicated: Eradicated means to eliminate completely, which does not fit the context of providing help or support.
• chimed: Chimed suggests joining in a conversation or activity, but it lacks the strong action-oriented connotation that 'jumped' provides.
