Difficulty: MediumInference and Logical Deduction

Read the following passage carefully:

Under the 2026 Regional Municipal Waste-to-Energy and Methane Abatement Directive, urban local bodies operating waste incineration facilities are mandated to capture at least 60% of emitted landfill methane gas and convert it into grid-compatible electricity. Facilities that achieve full methane capture compliance are eligible for state-backed green tariff rebates. However, the directive stipulates that any incineration plant receiving operational subsidies must process a minimum of 40% organic waste sourced exclusively from municipal collection drives rather than commercial third-party aggregators. Furthermore, municipal bodies that fail to report quarterly emissions telemetry to the central environmental portal face immediate suspension of their green tariff rebates, regardless of their actual gas conversion rates. A recently audited facility in District X successfully converted 70% of its captured methane into electricity and fulfilled all organic waste sourcing thresholds, yet had its green tariff rebate suspended by the regulatory authority.

Based strictly on the passage above, which of the following statements must be true regarding District X's incineration facility?

  1. The facility failed to submit its quarterly emissions telemetry to the central environmental portal.Answer
  2. B
    The facility sourced more than 60% of its organic waste from commercial third-party aggregators.
  3. C
    The facility experienced technical breakdowns in its methane incineration turbines, causing unrecorded methane leakage.
  4. D
    The central environmental portal is inefficient and improperly penalized compliant waste-to-energy facilities.

Answer

The facility failed to submit its quarterly emissions telemetry to the central environmental portal.
The passage specifies three distinct criteria: converting at least 60% methane, sourcing at least 40% organic waste from municipal drives, and submitting quarterly emissions telemetry. The text notes that missing telemetry leads to immediate rebate suspension regardless of conversion success. Because District X met both the 70% conversion mark and organic sourcing thresholds, its rebate suspension strictly implies that it failed to submit its quarterly emissions telemetry.

Step-by-Step Solution

1
Identify the conditions required for receiving and maintaining green tariff rebates.
Requirements are: (1) Capture and convert at least 60% of emitted methane into electricity, (2) Source at least 40% organic waste from municipal drives, and (3) Report quarterly emissions telemetry to the central portal (failure results in immediate rebate suspension regardless of conversion rate).
Establishing the precise regulatory conditions isolates the possible reasons for suspension.
2
Evaluate the audit findings given for District X's facility.
District X converted 70% of methane (exceeds the 60% threshold) and fulfilled all organic waste sourcing criteria.
Matching the facility's performance against the rules eliminates non-violations.
3
Deduce the mandatory logical cause for the rebate suspension.
Since the facility satisfied both performance metrics, the only remaining clause under the passage rules that causes immediate rebate suspension is the failure to submit quarterly emissions telemetry.
A valid inference must logically follow with absolute necessity strictly from the premises given in the text.
