Final answer:
In the literary work that Twyla and Roberta are from, it is not possible to categorically state whether they are high school students, college students, elementary school students, or graduate students. The correct option is 1) High school students
Step-by-step explanation:
The question pertains to the characters Twyla and Roberta from a literary work, indicating that they are characters in a story likely analyzed in an English or literature class at the college level. To determine what type of students Twyla and Roberta are based on the given options, we must refer to the context of the story they come from.
However, the information provided does not specify the exact work in which these characters appear; therefore, it is impossible to categorically state whether Twyla and Roberta are high school students, college students, elementary school students, or graduate students without further context.
As Twyla and Roberta are described to be 'inseparable friends at St. Bonny's,' a potential reader might infer that they are school-age characters, but the type of school is not clearly defined in the information provided.
The information about professors from various universities is extraneous and does not contribute to answering the question about the characters' student status. In light of this, an accurate answer cannot be provided without additional details regarding the story or work they are from. The correct option is 1) High school students
