The captain did his best to _____ a sense of unity among the new recruits. A. skillful B. applications C. billboard D. foster E. turnover F. portfolio G. ingredients H. confident I. contender J. solution

To solve this sentence completion, we need a verb that fits grammatically and logically with "a sense of unity." The context involves a captain trying to develop cohesion among new recruits.

Answer: D. foster

"Foster" means to encourage the development or growth of something, which directly matches the idea of building unity. Other options are either nouns ("applications," "billboard," "turnover," "portfolio," "ingredients," "contender," "solution") or adjectives ("skillful," "confident") that cannot function as the required verb in this sentence structure. The captain's action of nurturing unity makes "foster" the only appropriate choice.
