Final answer:
Military time, or the 24-hour clock, helps to not mix up AM and PM, by using a single continuous count up to 2359 hours, eliminating the need for separate morning and afternoon designations.
Step-by-step explanation:
Using military time helps to not mix up which two things? The correct answer is b) AM and PM. In military time, also known as the 24-hour clock, time is measured in a continuous 24-hour cycle. Instead of two sets of twelve hours as used in the 12-hour clock system, military time starts at midnight (0000 hours) and counts up to 2359 hours. This format helps to avoid confusion between morning and afternoon times which can occur with the AM and PM designations.
In the 12-hour clock system, each hour of the day is represented twice - once in the AM (ante meridiem, before midday) and once in the PM (post meridiem, after midday). For example, 7:00 in the morning is 7:00 AM and 7:00 in the evening is 7:00 PM. Using military time, 7:00 AM is simply 0700 hours and 7:00 PM is 1900 hours.
