You will be given a definition of a task first, then some input of the task.
In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: The ballad speaks of the Wabash River, which flows through Indiana, and reminisces about events that occurred there. The song has two verses and a chorus. The first verse is about the narrator's childhood on a farm and his love for his mother. The second verse is about his lost love, Mary. While the subjects of the verses are connected, the narrative of the chorus is detached from the verses as it seemingly reminisces nostalgically.Without speaking directly of death, both verses indicate the absence of a loved one, and the narrator's sadness and inability to cope with the grief. In the second verse, the narrator cannot bring himself to come near to his lost love's grave. The effort to avoid the subject of death and the focus on fond memories is typical of songs and societal sensibilities at the time.The melody of the song is a memorable tune made easy to learn because of its combination of harmonic repetition and contrast—elements that make music easy to remember while avoiding monotony. The recurrence and dissimilarity within the melody is similar to the patterns in many popular folk songs. Dresser, however, avoided the common 19th-century practice of using a portion of the refrain's melody in the verse. With little formal training in music theory, it is unlikely that Dresser purposefully made any methodical calculations when he composed the melody.Written for piano, guitar, and mandolin, the music begins in the key of G major with an Andante Moderato tempo. The verses follow a chord progression of G–C–G. The chorus transitions to B minor, and progresses as B–E–E, before returning to G–C–G in its final bars. Although the melody of the chorus is unique within the piece, it is in harmonic unity with the verses. An upbeat version played at a Andantino tempo was also adapted for play by small orchestras and big bands.
Output:
Which verses of the ballad about the Wabash River talk about missing a loved one?
