Passage:
In industrial ecology, eco-industrial parks (EIPs) are designed so that the waste products of one facility serve as raw material inputs for another, creating closed-loop systems. A primary challenge in establishing stable EIPs lies in the contractual alignment between co-dependent firms. While traditional bilateral supply contracts rely on flexible delivery schedules and market-indexed pricing to cushion external demand shocks, inter-firm byproduct exchanges require rigid physical synchronicity: if a primary manufacturing facility halts production due to a market downturn, its adjacent downstream recipient immediately loses its primary thermal energy or feedstock source.

To mitigate this vulnerability, early EIP designs favored anchoring networks around large, highly stable anchor tenants—typically municipal utility plants or petroleum refineries—whose continuous operations guaranteed an uninterrupted supply of waste heat and chemical byproducts. However, recent economic analyses demonstrate that over-reliance on a single anchor tenant creates a systemic vulnerability known as 'monopsonistic inertia.' If the anchor tenant restructures, upgrades to a zero-waste technology, or faces regulatory curtailment, all secondary facilities tied to its waste stream suffer severe operational disruptions. Consequently, modern EIP frameworks increasingly advocate for multi-node modular networks, wherein secondary facilities maintain auxiliary, secondary connections to regional utility grids, even though operating these backup systems incurs higher baseline overhead costs.

Based on the passage, which of the following can be logically inferred regarding secondary facilities operating within modern multi-node modular eco-industrial parks?

  1. They incur higher baseline operating expenses than they would if they relied exclusively on a primary anchor tenant's byproduct stream.Answer
  2. B
    They are completely immune to operational disruptions caused by zero-waste technology upgrades at neighboring facilities.
  3. C
    They prefer market-indexed pricing contracts over physical synchronicity agreements when negotiating byproduct exchanges with municipal utilities.
  4. D
    They primary rely on petroleum refineries rather than municipal utility plants to maintain continuous feedstock streams.
  5. E
    They eliminate the risk of monopsonistic inertia by replacing all physical synchronicity requirements with flexible delivery schedules.

Answer

Secondary facilities operating in modern multi-node modular networks incur higher baseline operating expenses than they would if they relied exclusively on a primary anchor tenant's byproduct stream.
The passage states that modern multi-node modular networks involve secondary facilities maintaining auxiliary grid connections as backup systems, and explicitly confirms that 'operating these backup systems incurs higher baseline overhead costs.' It directly follows that facilities maintaining these backup systems incur higher baseline operating expenses than they would if relying solely on an anchor tenant without such backup systems.

Step-by-Step Solution

1
Identify the premises regarding modern multi-node modular networks in the passage.
The final paragraph notes that modern EIP frameworks advocate for multi-node modular networks where secondary facilities maintain auxiliary connections to regional utility grids.
Understanding the specific operational features of modern multi-node modular networks is necessary to evaluate the options.
2
Analyze the stated economic consequence of maintaining these auxiliary connections.
The passage explicitly states that 'operating these backup systems incurs higher baseline overhead costs.'
Direct premise statements dictate what logically must be true about the overhead expenses of facilities with backup systems.
3
Deduce the logical inference.
Because operating auxiliary backup systems adds baseline overhead costs compared to relying solely on a primary anchor tenant without backup systems, operating within the modern framework increases baseline operating expenses.
An inference on GMAT Reading Comprehension must strictly follow from the explicit statements in the passage without external assumptions.
