Question

Which choice uses a colon correctly?

Answer 1

The first answer, "The library opens at 10:00 a.m Saturday." When using time, there should always be a colon between the hours and the minutes.

Answer 2

The answer is the first choice, "The library opens at 10:00 a.m. Saturday."

The colon in the second choice is misplaced. The colon should be placed between the 5 and the 0 in 500.

The colon after the word library in the third choice is not needed.

Instead of a colon being used to display the time in the fourth choice, a semi-colon is used, which is incorrect.
