Security notice analysis: "Beware of dogs, our dogs do not bark but distinguish guests from intruders" — determine which assumption is implicit about danger to intruders

Given data

• Statement: Beware of dogs; our dogs do not bark but are trained to distinguish genuine guests from intruders.
• Assumption I: Barking dogs bite rarely.
• Assumption II: These dogs could be dangerous for intruders.

Concept/Approach

A 'beware' warning is meaningful only if there is potential danger to intruders. The barking frequency is irrelevant because the dogs are said not to bark.

Step-by-Step reasoning
1) Warning implies risk to intruders ⇒ II is implicit.2) I is a general statement about barking behavior; the text does not depend on it ⇒ I is not implicit.

Verification/Alternative

Even if barking dogs often bite, these dogs do not bark; the key is that they can act against intruders.

Common pitfalls

• Overgeneralizing about canine behavior instead of focusing on the specific trained function stated.

Final Answer
Only assumption II is implicit.
