Final answer:
The approximate percentage of the labor force in the territorial north employed in the tertiary sector in 2019 is not provided, but analogous data from the United States indicates that nearly 80% of its workforce is in the tertiary sector. Hence, the closest approximations, given the options, would be 67% or 85%.
Step-by-step explanation:
The question asks for the approximate percentage of the labor force in the territorial north employed in the tertiary sector in 2019. The tertiary sector generally refers to services including retail, entertainment, financial services, and health care, as opposed to the primary sector which includes agriculture and mining, and the secondary sector which encompasses manufacturing and construction. While specific data for the territorial north in 2019 isn't provided, it's noted that in the United States, nearly 80 percent of the workforce is employed in the tertiary sector. Therefore, among the given options - 2%, 22%, 67%, and 85% - the closest approximation to the U.S. benchmark would likely be 67% or 85%.
However, given that we do not have the specific data for the territorial north in 2019, we should rely on analogous or nearby examples like the U.S. labor distribution. If the labor distribution in the territorial north follows a similar pattern to that of the United States, a figure above 50% would be reasonable. Thus, 67% would be a more conservative estimate, while 85% would suggest an even larger dominance of the sector. Without precise data, we cannot provide an exact percentage but would suggest that the proportion is likely quite high, aligning more closely with either 67% or 85% rather than 2% or 22%.
