GPT-4o mini · Answer

The statement that is most likely to explain the change in the proportion of green toads increasing from 20% to 50% is:

The environment changed such that green toads can blend into their surroundings better.

This explanation suggests that the environment favored the green coloration, likely due to changes in habitat or vegetation that provide better camouflage for green toads, which would enhance their survival and reproduction compared to brown toads. The other options do not directly support the increase in green toads' proportion in the same way.
