Why is light important? Please respond in 1–2 complete sentences using your best grammar.
Your Answer:
Light is important because we could not see God’s creation of color without it.
What are the characteristics of sound? Please respond in 1–2 complete sentences using your best grammar.
Your Answer:
Some characteristics of sound include how it can travel through a medium, and without this medium, it would be like we were in space where there is no sound.
