Worked practice questions

Into how many periods does the 12-hour clock divide a day?

  1. Three
  2. Six
  3. Four
  4. Two
Show answer and solution

Correct answer: D. Two

1. The 12-hour clock splits the 24 hours of a day into a.m. and p.m. 2. That gives exactly two periods of 12 hours each. 3. Three, four or six periods describe other schemes, such as the four Roman night watches. _Source: Wikipedia, 12-hour clock, Lead section_

The abbreviation a.m. comes from Latin words meaning what?

  1. After midday
  2. Midnight hour
  3. Before midday
  4. Morning meal
Show answer and solution

Correct answer: C. Before midday

1. a.m. stands for ante meridiem. 2. Ante means before, so the phrase means before midday. 3. After midday is p.m. (post meridiem), so that option is the other period. _Source: Wikipedia, 12-hour clock, Lead section_
