Difficulty: MediumStatement and Conclusions or Inferences

Read the following statements carefully.

1. All municipal water treatment facilities are classified as critical infrastructure.
2. No critical infrastructure is entirely exempt from federal oversight.
3. Some renewable energy grids are entirely exempt from federal oversight.

Which of the following conclusions logically follow from the given statements? (Select all that apply)

  1. No municipal water treatment facilities are entirely exempt from federal oversight.Answer
  2. Some renewable energy grids are not classified as critical infrastructure.Answer
  3. C
    All critical infrastructure systems are municipal water treatment facilities.
  4. D
    Some municipal water treatment facilities are also renewable energy grids.

Answer

The valid conclusions are that no municipal water treatment facilities are entirely exempt from federal oversight, and some renewable energy grids are not classified as critical infrastructure.
The valid conclusions correctly apply deductive rules. First, a chain of universally quantified statements (All water facilities are critical; No critical infrastructure is exempt) definitively proves that No water facilities are exempt. Second, combining a particular affirmative with a universal negative (Some renewable grids are exempt; No critical infrastructure is exempt) proves that Some renewable grids are not critical infrastructure.

Step-by-Step Solution

1
Analyze the logical relationship between municipal water treatment facilities and federal oversight.
All water treatment facilities are critical infrastructure, and critical infrastructure is never exempt from federal oversight. Therefore, water treatment facilities are never exempt.
This establishes the validity of the first correct conclusion using a standard hypothetical syllogism (All A are B, No B are C, therefore No A are C).
2
Analyze the logical relationship between renewable energy grids and critical infrastructure.
Some renewable energy grids are exempt from oversight, while critical infrastructure is never exempt. Therefore, the specific grids that are exempt cannot possibly be critical infrastructure.
This establishes the validity of the second correct conclusion (Some A are C, No B are C, therefore Some A are not B).
3
Evaluate the remaining options for logical fallacies.
The statement regarding all critical infrastructure being water treatment facilities incorrectly reverses the first premise. The statement linking water treatment with renewable energy assumes an unsupported overlap.
This step ensures that invalid inferences relying on flawed logic or external knowledge are successfully ruled out.
