Final answer:
The economic segment analysis includes interest rates, trade deficits or surpluses, and inflation rates, but not the move toward a contingent workforce, which is more related to labor market dynamics.
Step-by-step explanation:
An analysis of the economic segment of the external environment typically includes factors like interest rates, trade deficits or surpluses, and inflation rates. These elements directly affect economic performance, business strategies, and decision-making. However, the option stating 'the move toward a contingent workforce' does not fit within the traditional scope of an economic segment analysis; it is more related to labor market dynamics and business structure than to pure economic indicators such as interest rates, inflation, or trade balances.
Other elements that would fit within the economic segment are issues like the balance of trade concerns, the impact of rapidly growing exports, variations in oil prices, or shifts in the stock market. These economic factors contribute to the overall analysis by indicating potential challenges or opportunities for businesses within the economic environment.
