Hi, your job is to interpret a function f(x) that is implemented in the ./temp0/function.py script. f(x) takes word inputs, and applies a rule to the input word. 
The goal is to find a good simple description of f(x) that explains the function behavior on 10 inputs the user provides. Do not test any additional inputs.
After testing these 10 inputs, your description of the function should have two parts. 
[DESCRIPTION]: Describe in language the rule applied by the function.
[DOMAIN]: Is there part of the domain where the rule the function normally applies, does not hold? If so, describe that corruption. If not, describe the domain of the function where the rule applies.
Test the function on the following words: ["Marco Rubio", "Zircon", "South Korea", "The Grapes of Wrath", "The Barber of Seville", "Portugal", "Bear", "Tokyo"] by running the command COMMAND: PYTHON(./temp0/function.py "input1" "input2" ...). Replace "input1", "input2", ... with the words you want to test.
assistant:
COMMAND: PYTHON(./temp0/function.py "Marco Rubio" "Zircon" "South Korea" "The Grapes of Wrath" "The Barber of Seville" "Portugal" "Bear" "Tokyo")

Response: Function input - output pairs: (Marco Rubio, undefined) (Zircon, undefined) (South Korea, South Korea) (The Grapes of Wrath, undefined) (The Barber of Seville, undefined) (Portugal, Portugal) (Bear, undefined) (Tokyo, undefined) 

assistant:
Based on the provided input-output pairs, here is a description of the function f(x):

[DESCRIPTION]: The function f(x) seems to return the input word unchanged if it consists of two words which both start with a capital letter. If the input doesn't meet this criterion, the output is undefined.

[DOMAIN]: The function applies the rule to input words that are composed of two words, both starting with a capital letter. The rule does not hold for inputs that do not meet this criterion (either one-word inputs, two or more words with lowercase letters, or inputs with special characters), and the function simply returns 'undefined' for them.

To test the remaining 2 inputs, please provide them in the following format: COMMAND: PYTHON(./temp0/function.py "input1" "input2"). Replace "input1" and "input2" with the words you want to test.
