Zorluk: OrtaSufficient Assumption

Read the following argument:

Any synthetic chemical compound that bonds effectively with the Z-receptor will inhibit the replication of the delta-virus. The newly synthesized compound, Brivanex, was designed specifically to target the Z-receptor. Therefore, Brivanex will successfully cure patients infected with the delta-virus.

Is the following statement true or false?

The assumption 'Any compound that inhibits the replication of the delta-virus will successfully cure patients infected with it' is sufficient to logically guarantee the argument's conclusion.

Cevap: Cevap

Cevap

False
The correct evaluation is False. A sufficient assumption must leave no logical gaps. While the proposed statement bridges the gap between inhibiting the virus and curing patients, it completely ignores the gap between Brivanex being 'designed to target' the receptor and actually 'bonding effectively' with it. Without bridging both gaps, the conclusion remains unproven.

Adım Adım Çözüm

1
Identify the premises and the conclusion of the argument.
Premise 1: Bonds effectively with Z-receptor → Inhibits replication. Premise 2: Brivanex was designed to target the Z-receptor. Conclusion: Brivanex → Cures patients.
Deconstructing the argument is necessary to map out the existing logical chain and locate missing links.
2
Analyze the proposed assumption to determine its conditional structure.
The proposed assumption translates to: Inhibits replication → Cures patients.
We must understand exactly what logical bridge the assumption provides.
3
Apply the assumption to the premises to test for deductive validity.
Combining Premise 1 and the assumption yields: Bonds effectively → Inhibits replication → Cures patients. However, Premise 2 only states Brivanex was 'designed to target' the receptor.
A sufficient assumption must leave zero ambiguity and force the conclusion to be 100% true based on the premises.
4
Determine if the conclusion is fully guaranteed.
Because 'designed to target' does not deductively guarantee 'bonds effectively,' the chain is broken. The conclusion that Brivanex cures patients is not guaranteed.
If any logical gap remains, the assumption is not sufficient.
