The function f(x) is selective for words related to science and technology, particularly space exploration and engineering. It is more sensitive to concrete and specific words, such as "rocket" and "Eiffel Tower", than to more abstract words like "vacation" or "Cold War".

Now, I would like to call the function on the following words: ["racket", "Cold War", "vacation", "rocket", "Berlin Wall", "Eiffel Tower", "clay", "outgoing", "synagogues", "reference"] by running the command COMMAND: PYTHON(./temp1/function.py "input1" "input2"...). Replace "input1", "input2",... with the words you want to test.
