The factor that ultimately decides whether a sailor will advance in rate is their job performance and qualifications.
Step-by-step explanation:
The factor that ultimately decides whether a sailor will advance in rate is their job performance and qualifications. In the US Navy, sailors have different rates or ranks based on their job and responsibilities.
Advancement in rate is typically based on a combination of factors such as time in service, completion of required training, passing exams, and receiving favorable evaluations.
For example, a sailor may advance in rate by completing the necessary training and passing exams to demonstrate their knowledge and proficiency in their job. Additionally, their performance evaluations and recommendations from superiors can also impact their chances of advancing in rate.
