Responsible, involved, and helped are effective action words to create a power statement.

The assertion that responsible, involved, and helped are effective action words for creating a power statement is false. Power statements are typically characterized by dynamic and impactful verbs that convey a strong sense of accomplishment and agency. Words like "achieved," "executed," or "led" carry a more authoritative presence and depict active contributions that emphasize results or initiatives taken.

In contrast, "responsible," "involved," and "helped" tend to imply a more passive or less assertive role. They suggest a level of participation but lack the strong, decisive connotation that is often essential for a power statement, which should ideally inspire confidence and highlight leadership or significant achievement. Thus, the correct understanding is that to craft effective power statements, one should focus on using more vigorous and assertive language.
