Metals: Conductivity Rule
The question starts with a general statement about metals:
- Premise 1: All metals are good conductors of electricity. This means that if something is a metal, it definitely has the property of conducting electricity well.
Copper: Metal Status
Next, the question provides specific information about copper:
- Premise 2: Copper is a metal. This places copper into the category defined in the first premise.
Conclusion: Copper's Conductivity
Now, we need to combine these two pieces of information to find the logical conclusion.
Since all metals are good conductors (Premise 1), and copper is confirmed to be a metal (Premise 2), we can apply the general rule to the specific case of copper.
Therefore, the conclusion that logically follows is that copper must also be a good conductor of electricity.
Let's look at the options provided:
- Option 1: Copper is not a conductor - This is incorrect because copper is a metal, and all metals are conductors.
- Option 2: Copper is a metal only - This statement might be true in other contexts, but it doesn't follow logically from the given premises regarding conductivity.
- Option 3: Copper is a poor conductor - This contradicts the first premise, which states all metals are *good* conductors.
- Option 4: Copper is a good conductor - This is the correct conclusion derived directly from applying the general rule (all metals are good conductors) to the specific instance (copper is a metal).
The logical deduction is straightforward: If a group (metals) has a specific characteristic (being good conductors), and an individual item (copper) belongs to that group, then the individual item must also possess that characteristic.
