The function f(x) seems to be selective for the concepts related to geology and the color blue as it gives higher values for words like "rocks", "minerals", "ocean", and "blue". The values indicate a stronger association with geology (rocks and minerals) than with the color blue (ocean and blue). Other concepts such as diving, France, classical music, outgoing personality, rhyming, and light receive significantly lower values, implying that the function is not selective for these concepts.
