Depending on how far the source where the signal is coming from is, radio waves travel at the speed of light. If the civilization lives in a star system that is 20 light years away from us, the signal would take 20 light years to reach us.

(1 light year = 1 normal year but traveling or moving at the speed of light).

Why was silk production eventually ended and cotton production started instead?
Ymorist [56]

According to historical accounts, silk production eventually ended and cotton production started instead because:

"Georgia’s climate was not good for silkworms but was good for growing cotton."

  • This is evident in the fact that silkworms are very susceptible to tough Georgia temperatures.

  • Silk production was profitable around the middle of the 18th century, and England decided to enter the market and compete with other Europeans such as French and Italian.

Hence, in this case, the correct answer is option B. "Georgia’s climate was not good for silkworms but was good for growing cotton."
