Model input

User/Human

Who does "he" refer to in the last sentence? Only return the name.

Tom and Jerry were playing in the yard. Spike, the dog, was watching them from his kennel. Suddenly, he started barking loudly.

Model response

Spike 

The last sentence's "he" refers to the most recently introduced male entity capable of the action (barking), which is the dog explicitly named and described with a kennel in the prior sentence. Pronoun resolution follows standard discourse rules prioritizing recency, grammatical gender match, and semantic plausibility (dogs bark; a cat or mouse in the Tom & Jerry franchise do not).
