14. Given the words influence, fluid, and fluctuate, what does the root flu mean?

Answer: D

Explanation:

The root flu means flow.

The root "flu" is derived from Latin, where it is associated with the concept of flowing. In this context, it indicates movement or the act of flowing, which aligns perfectly with the word "flow."

A) through

While "through" can imply a sense of movement, it does not capture the essence of the root "flu." This choice does not reflect the meaning related to flowing or movement of a liquid.

B) in

The term "in" denotes a position or state but does not convey the idea of movement or flow. Thus, this option fails to represent the root "flu" accurately.

C) pass

The word "pass" can imply movement, but it lacks the specific connotation of flowing associated with "flu." Therefore, it does not adequately define the root meaning.

D) flow

This option directly corresponds to the meaning of the root "flu." It signifies the action of moving steadily and continuously, which is the fundamental essence of the root.

Conclusion

The root "flu" is definitively tied to the concept of flow, making option D the correct choice. The other options do not encapsulate the meaning of "flu," as they relate to different aspects of movement or position rather than the specific action of flowing.
