The odd item from the list is "Things fall Apart."
The other three items in the list, "Night Rain," "Stanley Meets Mutesa," and "Nightfall in Soweto," are all titles of literary works that refer to a specific time or event. "Night Rain" and "Nightfall in Soweto" both refer to a specific time of day, while "Stanley Meets Mutesa" refers to a specific event.
On the other hand, "Things fall Apart" is a title that does not refer to a specific time or event. Rather, it is a more abstract phrase that can be interpreted in many different ways. This makes it different from the other titles, which all have a more concrete reference point.
"Things fall Apart" is also the title of a novel by Chinua Achebe, which tells the story of a Nigerian village and its people's struggles to maintain their way of life in the face of colonialism. So not only is it different from the other titles in terms of its abstractness, but it also has a different theme and genre compared to the others, which are more focused on specific times and events.
