The passage states:
Regions with a higher density of tech companies tend to have lower unemployment rates.
The presence of tech companies stimulates local economies by creating a high demand for skilled labor.
This demand provides jobs within tech companies and boosts secondary employment in supporting industries.
The government is considering incentives to attract tech companies to economically depressed regions based on these findings.
Now, let's evaluate each option:
(A) Regions without a high density of tech companies will benefit from similar economic stimulation if tech companies are introduced there.
The passage suggests that tech companies stimulate local economies and reduce unemployment, but it does not provide direct evidence that this effect will occur in all regions without a high density of tech companies. This statement is plausible but not necessarily true based on the information given.
(B) Incentives to attract tech companies to economically depressed regions will significantly lower the unemployment rates in those regions.
The passage implies that attracting tech companies to an area with incentives would likely stimulate the local economy and create jobs, suggesting that unemployment rates would decrease. However, it does not guarantee that the decrease will be significant, only that tech companies tend to reduce unemployment where they are present.
(C) Tech companies tend to create more jobs in regions where they are concentrated due to increased demand for skilled labor and supporting industries.
This statement aligns directly with the passage's explanation that tech companies create a high demand for skilled labor and boost secondary employment. It is a logical conclusion based on the information provided.
(D) The overall economy of a region is always improved by the presence of tech companies.
While the passage suggests positive effects on employment and local economies, it does not claim that the overall economy is always improved by the presence of tech companies. There could be other factors influencing the overall economy that are not addressed.
(E) Regions that are economically depressed lack the skilled labor necessary to support the influx of tech companies without government incentives.
The passage does not mention anything about the availability of skilled labor in economically depressed regions or the necessity of government incentives specifically to support skilled labor. This statement is not supported by the given information.
Based on the analysis, the statement that must be true according to the passage is:
(C)
