Answer:
The Sun will not rise before 6 o'clock.
In this sentence, the appropriate preposition to fill in the blank is "before."
The word "before" is used to indicate that the Sun's rising will occur prior to the specified time, which in this case is 6 o'clock. It implies that the Sun will rise at a time earlier than 6 o'clock.
Here's an example to illustrate this:
If someone says, "I need to leave before 6 o'clock to catch my flight," it means that the person needs to depart earlier than 6 o'clock in order to reach the airport on time.
In the given sentence, "before" is used in a similar way to indicate that the Sun's rising will happen earlier than 6 o'clock.
