Final answer:
The sentence 'Frances has plenty of time to devote to her painting.' includes the infinitive 'to devote'. In the diagnostic sentences, 'convince' replaces 'analysis' and 'frustrated' replaces 'explanation' while also changing the verb structure to maintain correct grammar.
Step-by-step explanation:
To change the italicized group of words into an infinitive and rewrite the sentence: "Frances has plenty of time that she can devote to her painting.", we must transform the phrase 'that she can devote to her painting' into an infinitive phrase. The sentence with the infinitive would then be: "Frances has plenty of time to devote to her painting."
Looking at the examples you provided:
- The mayor's analysis of the issue did not convince journalists.
- Bob's explanation of why he was late frustrated his wife.
For these sentences, we replace the italicized nouns with verbs:
- Character(s): The mayor
- Action(s): Convincing
- Revised: The mayor did not convince the journalists about the issue.
- Character(s): Bob
- Action(s): Explaining
- Revised: Bob's being late frustrated his wife.
