Zorluk: OrtaMust Be True Questions

Read the following stimulus and evaluate the statement below.

Stimulus: To qualify for a municipal architectural preservation grant, a building must have been constructed prior to 1930 and must retain its original exterior facade. Furthermore, any building that retains its original exterior facade is automatically exempt from the city's modern exterior cladding regulations. The Wellington Building was constructed in 1928 and is exempt from the modern exterior cladding regulations.

Statement: Based on the information provided, it must be true that the Wellington Building qualifies for the municipal architectural preservation grant.

Cevap: Cevap

Cevap

False
The statement is false because the conclusion relies on an illegal reversal. The stimulus establishes that retaining an original facade guarantees an exemption from modern exterior cladding regulations. However, it does not state that the ONLY way to be exempt is to retain the original facade. Since the Wellington Building might be exempt for a different reason, we cannot definitively conclude it retains its original facade, and therefore we cannot conclude it qualifies for the grant.

Adım Adım Çözüm

1
Diagram the first conditional statement regarding the grant.
Grant -> Constructed Before 1930 AND Retains Original Facade
To identify the necessary conditions for a building to qualify for the architectural preservation grant.
2
Diagram the second conditional statement regarding the exemption.
Retains Original Facade -> Exempt from Cladding Regulations
To establish the relationship between the facade and the cladding regulations.
3
Analyze the known facts about the Wellington Building.
Wellington Building = Constructed Before 1930 (1928) AND Exempt from Cladding Regulations.
To see if the known facts satisfy the necessary conditions for the grant.
4
Determine if the Wellington Building must retain its original facade.
We cannot determine this. Being exempt from cladding regulations is a necessary condition of retaining the original facade, but it is not a sufficient condition.
Concluding that the building has its original facade based on its exemption status would be an illegal reversal.
5
Evaluate the final statement.
Because we cannot prove the Wellington Building retains its original facade, we cannot prove it qualifies for the grant.
A 'Must Be True' statement requires 100% certainty based only on the provided premises.
