Explanation:

For the first question about the scientist's prediction in "Alien Contact", based on the documentary's content, the scientist predicted we would get a signal or sign of extraterrestrial life by 2025. For the second question about when a message from across the Milky Way was sent, given the vastness of the galaxy and the speed of light, a message from across the Milky Way would have been sent billions of years ago (note: the option has a typo, likely "billions of years ago").

Answer:

First Question: C. By 2025
Second Question: B. billion of years ago (assuming the intended option is "billions of years ago")
