Cohesion refers to the linguistic elements that link sentences together, while coherence relates to the underlying logical connection of ideas. Analyze the following excerpt: "John arrived late. This annoyed his boss. He had missed the meeting." and identify the specific cohesive devices employed.

I. "This" is an example of reference, specifically referring back to the entire preceding clause ("John arrived late").
II. "He" is an example of anaphora, referring back to the antecedent "John".
III. The connection between the sentences relies on lexical repetition rather than pronominal reference. 

It is correct what is stated
