Final answer:
The true statement reflects Maslow's hierarchy of needs theory, where one must satisfy basic needs before higher-level needs become motivating factors.
Step-by-step explanation:
The statement, Maslow proposed that we are motivated simultaneously by several needs, but the strongest motivation comes from the lowest unsatisfied need, is true. Abraham Maslow's theory of motivation is encapsulated in his hierarchy of needs, emphasizing the precedence of fulfilling lower-level needs before upper-level needs can become motivating factors. According to Maslow, basic physiological needs for things like food and water must be met before one can be motivated by needs higher up in the hierarchy, such as esteem or self-actualization. Maslow also introduced the concept of self-transcendence, a level beyond self-actualization that revolves around finding higher meaning and purpose.
