Zorluk: Çok zorCannot Be True Questions

Under the revised zoning laws of Oakhaven, any developer who constructs a high-density residential complex must secure a municipal waiver. Securing a municipal waiver requires the developer to allocate at least 20 percent of the units for low-income housing, unless the developer has received a historical preservation tax credit. However, no developer who receives a historical preservation tax credit is eligible to apply for the state urban revitalization grant. According to city records, every developer currently constructing a high-density residential complex in Oakhaven has been awarded the state urban revitalization grant.

Based on the information provided, it could be true that there is a developer currently constructing a high-density residential complex in Oakhaven who has not allocated at least 20 percent of the units for low-income housing.

Cevap: Cevap

Cevap

The statement is false. It is logically impossible for a developer in this scenario to avoid allocating at least 20 percent of the units for low-income housing.
The correct evaluation is false. The stimulus establishes that every developer constructing a high-density residential complex has the state urban revitalization grant. Because having a historical preservation tax credit precludes a developer from receiving this grant, none of these current high-density developers have the historical tax credit. To secure the required municipal waiver without possessing the historical tax credit, a developer is strictly required by the 'unless' clause to allocate at least 20 percent of the units for low-income housing. Therefore, the scenario described in the statement is a logical impossibility.

Adım Adım Çözüm

1
Translate the first and final premises regarding high-density developers.
High-Density -> Municipal Waiver, and High-Density -> Revitalization Grant.
To establish the baseline mandatory conditions for all developers currently building high-density complexes.
2
Translate the exclusionary premise and apply its contrapositive.
Historical Credit -> NOT Revitalization Grant. Contrapositive: Revitalization Grant -> NOT Historical Credit.
To connect the developers' known grant status to their eligibility for the tax credit.
3
Translate the 'unless' conditional regarding the municipal waiver.
Municipal Waiver -> Low-Income Allocation OR Historical Credit. This is logically equivalent to: If NOT Historical Credit, then Low-Income Allocation must be met.
'Unless' introduces a necessary condition that must be fulfilled if the alternative condition is absent.
4
Chain the deductions together to determine what must be true.
High-Density developers have the Revitalization Grant. Therefore, they do NOT have the Historical Credit. Because they must have a Municipal Waiver and lack the Historical Credit, they MUST provide the Low-Income Allocation.
To form a complete deductive chain proving that High-Density -> Low-Income Allocation.
5
Evaluate the given statement against the deduced rule.
The statement claims a high-density developer could fail to provide the low-income allocation. Since we proved they absolutely must provide it, the statement describes a scenario that cannot be true, making the statement false.
To answer the prompt based on strict logical necessity.
