Difficulty: HardMust Be True Questions

Under the new oceanographic regulations, any mining corporation that holds a Deepwater Extraction Permit must submit an annual benthic ecosystem report to the regulatory commission. Any corporation that submits an annual benthic ecosystem report is authorized to operate autonomous dredging vehicles. However, no corporation that is authorized to operate autonomous dredging vehicles can qualify for the marine conservation tax credit. Furthermore, most mining corporations currently operating in the Abyssal Sector hold a Deepwater Extraction Permit.

Based on the regulations above, which of the following statements must be true? (Select all that apply)

  1. Any mining corporation that qualifies for the marine conservation tax credit does not hold a Deepwater Extraction Permit.Answer
  2. Most mining corporations currently operating in the Abyssal Sector do not qualify for the marine conservation tax credit.Answer
  3. C
    Any mining corporation that submits an annual benthic ecosystem report holds a Deepwater Extraction Permit.
  4. D
    Most mining corporations authorized to operate autonomous dredging vehicles currently operate in the Abyssal Sector.
  5. E
    Any mining corporation that does not hold a Deepwater Extraction Permit qualifies for the marine conservation tax credit.

Answer

The correct statements are that any corporation qualifying for the tax credit lacks a permit, and that most corporations in the Abyssal Sector do not qualify for the tax credit.
The correct options are logically proven by the text. The first correct option relies on the contrapositive of the stimulus rules: since holding a permit strictly guarantees losing the tax credit, qualifying for the credit guarantees a corporation does not hold a permit. The second correct option relies on chaining a quantifier with a universal rule: since most Abyssal Sector corporations hold a permit, and all permit holders lose the credit, most Abyssal Sector corporations lose the credit.

Step-by-Step Solution

1
Diagram the universal conditional statements provided in the stimulus.
Permit -> Report; Report -> Vehicles; Vehicles -> NOT Tax Credit.
To establish the formal logical chain linking the distinct corporate requirements and restrictions.
2
Chain the universal conditionals together and form their contrapositive.
Chain: Permit -> Report -> Vehicles -> NOT Tax Credit. Contrapositive: Tax Credit -> NOT Vehicles -> NOT Report -> NOT Permit.
Deductions in Must Be True questions frequently rely on valid conditional chains and their contrapositives.
3
Diagram the quantifier statement and integrate it with the universal chain.
Abyssal Sector -most-> Permit. Linking this to the chain: Abyssal Sector -most-> Permit -> NOT Tax Credit. Therefore, Abyssal Sector -most-> NOT Tax Credit.
Formal logic permits applying a universal conditional to a subset defined by a 'most' statement.
4
Evaluate the answer choices strictly against these proven deductions.
The option stating 'Tax Credit -> NOT Permit' matches the contrapositive chain. The option stating 'Abyssal Sector -most-> NOT Tax Credit' matches the integrated quantifier chain. The remaining options represent classic formal logic errors.
Correct options in standard Must Be True questions must be 100% provable without any outside assumptions.

Key Concept

Chaining formal conditional statements, forming contrapositives, and applying quantifiers to universal rules.
