Difficulty: EasyIdentifying Conclusions and Main Claims

Many urban planners argue that introducing high-speed rail lines between adjacent metropolitan areas always stimulates economic growth in smaller intermediate towns along the route. However, a recent comprehensive study of regional transit networks over the past two decades demonstrates that such rail links predominantly funnel commerce and skilled labor toward the larger terminal cities. Consequently, rather than revitalizing smaller intermediate municipalities, high-speed rail connections often accelerate their economic decline by facilitating outward commuting and business relocation. Therefore, municipal governments in smaller towns should refrain from heavily subsidizing high-speed rail infrastructure under the assumption of guaranteed local growth.

Which of the following express main claims or conclusions advocated by the author in the passage above? (Select all that apply.)

  1. Municipal governments in smaller towns should avoid heavily subsidizing high-speed rail projects based on the assumption that local growth is guaranteed.Answer
  2. High-speed rail links between major cities frequently hasten the economic decline of smaller intermediate towns along the route.Answer
  3. C
    High-speed rail projects inevitably lead to a sudden decrease in the total commercial activity of larger terminal cities.
  4. D
    Urban planners designed regional transit networks over the past two decades with the explicit goal of harming intermediate municipalities.
  5. E
    High-speed rail lines consistently foster vibrant local economic expansion in every smaller town situated along their path.

Answer

The main claims advocated by the author are that municipal governments in smaller towns should refrain from heavily funding high-speed rail based on assumed growth, and that high-speed rail links often accelerate the economic decline of smaller intermediate municipalities.
The author advocates two main related claims: the final prescriptive conclusion that small-town municipal governments should not heavily subsidize high-speed rail expecting guaranteed local growth, and the supporting main claim that high-speed rail connections often accelerate the economic decline of intermediate towns by directing labor and commerce to terminal cities.

Step-by-Step Solution

1
Analyze the passage structure and identify structural indicator words.
The word 'However' introduces a counter-position to urban planners, 'Consequently' introduces an intermediate finding, and 'Therefore' signals the final main conclusion.
Structural signals clearly separate background opinions from the author's primary argument and main recommendation.
2
Evaluate statements to determine which represent claims endorsed by the author.
The author explicitly asserts that high-speed rail accelerates economic decline in smaller towns and concludes that smaller municipalities should not subsidize such infrastructure based on false growth assumptions.
Both of these claims reflect the author's central thesis and primary recommendation.
