The office remains open from 10 AM to 6 PM.

II. Office is closed after 6 PM.

Question

Accepted Answer

1. The statement says the office is open from $10\ 	ext{AM}$ to $6\ 	ext{PM}$.  
2. If it is open only in that time, it is not open before $10\ 	ext{AM}$.  
3. So employees cannot enter before $10\ 	ext{AM}$.  
4. By the same logic, it is not open after $6\ 	ext{PM}$, so the office is closed after $6\ 	ext{PM}$.  
Both conclusions follow.
