Final answer:
The percentage of incoming first-year multicultural students from 2018 cannot be determined without specific data for that year. The provided reference information does not supply the needed statistics; hence a definitive answer cannot be given based on the available information.
Step-by-step explanation:
To determine what the percentage of incoming first-year multicultural students from 2018 was, we would need specific data relating to the demographics of the freshman class of that year. None of the information provided directly answers the question about the percentage of incoming first-year multicultural students from 2018. Instead, we have data on various topics such as the likelihood of a student not living within five miles of a community college, attitudes of different ethnic groups towards intermarriage, and workforce diversity projections.
However, based on the data provided about racial and ethnic diversity, we can infer that the multicultural student population in any educational environment is likely to be reflective of broader societal trends. Given the data about historical diversity in the US workforce and projections for the future, it is plausible to assume that the percentage of multicultural students was significant. Still, without exact figures for the year 2018, we cannot definitively select any of the options provided in the question (A) 20%, (B) 30%, (C) 40%, or (D) None of the above.
In conclusion, to accurately answer the specific question posed, data specifically related to incoming first-year multicultural student percentages for the year 2018 would be necessary.
