Which phrase correctly completes this sentence: We will need to __________ additional resources to complete the project on time.

The phrase "allocate additional resources to complete the project on time" is the most appropriate choice because "allocate" specifically means to set aside or assign resources for a particular purpose. In the context of project management, this is often necessary to ensure that all required inputs, such as funds, personnel, or materials, are effectively directed toward the completion of the project within the established timeline.

In contrast, "assess" refers to evaluating or estimating the nature, ability, or quality of something, which does not imply actively providing or assigning resources. "Distribute" suggests spreading resources out to various recipients rather than designating them for a specific project, leading to potential misalignment with the need. Lastly, "reduce" implies cutting down on resources, which would directly contradict the need to gather more resources for timely project completion.
