Final answer:
The sentence 'What a wonder!' is expressed with a rising intonation, indicative of surprise or amazement, which can also be discerned in various literary examples where characters' expressions are marked by strong emotions or questioning.
Step-by-step explanation:
The intonation in the sentence 'What a wonder!' typically would exhibit an uplift or a rise in pitch, reflecting the speaker's expression of surprise or amazement. Intonation involves the variation of pitch while speaking and is used to convey different meanings or emotional nuances. In English, exclamatory sentences such as this one often involve a rising intonation to emphasize the speaker's strong feelings.

In the given examples, words such as 'wonderful' and phrases like 'What do you think?' also suggest exclamatory or inquisitive intonation, reflecting the characters' emotions or rhetorical questioning, respectively.
