Explanation:
The answer is the first option or "candles." In ancient times the people would lit candles and place them in difference places in their homes, temples, etc... to produce light.

Hope this helps.
Answer:
Because there is too smooth
Since acceleration is constant
So the distance moved in constant acceleration will be given as
as we know that
t = 17 s
so distance moved is given by
so distance moved will be 170 m
