Question

To determine which conclusions logically follow from the given statements, let's analyze them step-by-step:

**Statements:**  
1. No keyboard is a mouse.  
2. All mice are computers.  
3. All computers are laptops.

**Conclusions:**  
1. **All mice are laptops.**  
2. **All computers can never be keyboards.**

Accepted Answer

#### **Conclusion I: All mice are laptops**  
- From Statement 2: *All mice are computers*.  
- From Statement 3: *All computers are laptops*.  
- By transitivity, **all mice must be laptops** (since mice → computers → laptops).  
- **Conclusion I logically follows**.

#### **Conclusion II: All computers can never be keyboards**  
- Statement 1 says *No keyboard is a mouse*, but it does **not** state that keyboards cannot be computers or laptops.  
- While all computers are laptops, keyboards could theoretically belong to the "computer" category (as long as they are not mice). The statements do **not** explicitly prohibit this relationship.  
- Syllogistically, combining *No keyboard is a mouse* (E-type) and *All mice are computers* (A-type) only allows the conclusion *Some computers are not keyboards* (particular negative), **not** the universal claim *All computers can never be keyboards*.  
- **Conclusion II does not logically follow**.

### Final Answer:  
**(1) Only conclusion I follows**
