Final answer:
Leaders use various styles to guide their groups toward success, with each style having its own benefits and challenges.
Step-by-step explanation:
Leaders and other group members indeed move their groups toward success and/or the completion of their tasks by tapping into various types of power, making the original statement true. Different leadership styles such as democratic, authoritarian, and laissez-faire play unique roles in guiding the group toward its goals. Democratic leaders encourage participation and consensus, which can be effective but slow. Authoritarian leaders issue orders and focus on results, which can be efficient but potentially alienating. Laissez-faire leaders are hands-off, allowing for autonomy, but risking a lack of progress without self-motivation and clear goals within the group.
