Zorluk: ZorNecessary Assumption

Sociolinguist: In the isolated community of Vespera, young adults use traditional idioms far less frequently than older adults do. Based on this observation, some researchers conclude that traditional idioms in Vespera are inevitably dying out. This conclusion is unwarranted. Young adults in Vespera are systematically excluded from the Council of Elders, a prestigious governing body where the use of traditional idioms is both expected and heavily utilized during all proceedings.

Which one of the following is an assumption required by the sociolinguist's argument?

  1. At least some of Vespera's current young adults will eventually use traditional idioms upon becoming members of the Council of Elders.Cevap
  2. B
    All young adults in Vespera will eventually be admitted to the Council of Elders and will be required to use traditional idioms.
  3. C
    The researchers who concluded that the idioms are dying out have never observed a proceeding of the Council of Elders.
  4. D
    Traditional idioms are used in Vespera exclusively during the official proceedings of the Council of Elders.
  5. E
    The prestige of the Council of Elders is the primary cause of the older adults' frequent use of traditional idioms in everyday conversation.

Cevap

The correct statement is that at least some of Vespera's current young adults will eventually use traditional idioms upon becoming members of the Council of Elders.
The sociolinguist argues that traditional idioms are not dying out, relying on the fact that the Council of Elders heavily utilizes these idioms and currently excludes young adults. For this premise to guarantee the survival of the idioms after the older generation passes, it must be true that the younger generation will adopt the idioms when they eventually age into the Council. Applying the Negation Test confirms this: if we assume that none of the young adults will ever use the idioms even upon joining the Council, the sociolinguist's evidence becomes irrelevant and the argument collapses.

Adım Adım Çözüm

1
Identify the main conclusion of the sociolinguist's argument.
The conclusion is that the researchers' claim is unwarranted; therefore, traditional idioms in Vespera are not inevitably dying out.
Isolating the conclusion is the first prerequisite for finding the unstated assumption that supports it.
2
Identify the premise used to support this conclusion.
The supporting premise is that young adults are systematically excluded from the Council of Elders, a prestigious body where traditional idioms are mandatory.
The assumption will be the unstated link bridging this supporting evidence to the main conclusion.
3
Locate the logical gap between the premise and the conclusion.
The argument jumps from the premise 'young adults are currently excluded from a council that uses idioms' to the conclusion 'idioms are not dying out.' This requires assuming that these young adults will eventually enter the council and adopt the idioms.
Necessary assumptions always address the missing logical link in the argument's structure.
4
Evaluate the choices using the Negation Test.
Negating the correct statement yields: 'None of the current young adults will ever use traditional idioms upon joining the Council.' This destroys the argument, proving it is the necessary assumption.
The Negation Test is the definitive way to prove whether an assumption is logically necessary for the conclusion to stand.
