Which one of the following, if assumed, enables the argument's conclusion to be properly drawn?

  1. A
    Every painting displayed on the first floor of the building is part of the permanent collection.
  2. Every painting that is part of the permanent collection must be displayed on the first floor of the building.Cevap
  3. C
    Any painting not considered part of the permanent collection must not be displayed on the first floor of the building.
  4. D
    Most paintings that are considered part of the permanent collection must be displayed on the first floor of the building.
  5. E
    Paintings in the permanent collection are generally more valuable and thus require the security features found on the first floor.

Cevap

The correct assumption is that every painting that is part of the permanent collection must be displayed on the first floor of the building.
The argument provides the premise (A -> B) and draws the conclusion (A -> C). To make this logically valid, we must bridge the gap between B and C with the rule (B -> C). The correct answer explicitly provides this missing rule: if a painting is in the permanent collection, it must be displayed on the first floor.

Adım Adım Çözüm

1
Identify the argument's premise.
If a painting was acquired before 1900, it is part of the permanent collection (Acquired Before 1900 -> Permanent Collection).
This establishes the starting condition of the logic chain.
2
Identify the argument's conclusion.
If a painting was acquired before 1900, it must be displayed on the first floor (Acquired Before 1900 -> First Floor).
This is the final destination the author is trying to prove.
3
Find the logical gap between the premise and the conclusion.
The argument leaps from 'Permanent Collection' in the premise to 'First Floor' in the conclusion without connecting them.
For the conclusion to be 100% guaranteed, there must be no unconnected terms.
4
Formulate the necessary bridge to guarantee the conclusion.
We must state that anything in the permanent collection must go to the first floor (Permanent Collection -> First Floor).
Chaining 'Acquired Before 1900 -> Permanent Collection' with 'Permanent Collection -> First Floor' deductively yields 'Acquired Before 1900 -> First Floor'.
