Which activity is most likely a result of a sudden, unexpected change in the
environment?

well, i believe that the answer is 2. : 3

i do believe the correct answer would be the third one. location c, because earth is tilted away from the sun at this time

hope this

explanation:

the sun shines white and black light to our planet. the white light has all the colors in it. in our upper atmosphere, we have dust particles and oxygen molecules. the white light meaning all of the colors in a rainbow shines through the upper levels of the atmopshere and the blue light scatters across the entire planet. that is why our sky is blue.
