After running these experiments, it seems that the function f(x) is selective for words that are related to animals or nature. The function returns a high value for words like "dog" and "cat" that are clearly associated with animals, and a lower value for words like "apple" that are not directly related to animals or nature. The function also returns a moderate value for words like "tree" that are related to nature but not necessarily animals.

[DESCRIPTION]: The function f(x) appears to be selective for words related to animals or nature, returning high values for words directly associated with animals and lower values for words not related to animals or nature.

Can you think of any other words that might be related to animals or nature that we could test with the function?
