The correct answer to this open question is the following.
Although the question is incomplete because it does not include excerpts, paragraphs, or statements, we can say the following.
The renewed interest in Wole Soyinka's works could be because he used irony and some humor to criticize social problems in Nigeria, as well as a serious criticism of Nigerian government officials, putting emphasis on military dictators.
Soyinka is a Nigerian writer that has always been interested in the social condition of the people of Nigeria under tough political and economic times. He has written many essays, poems, even plays that have exhibited in his country. That is why so many people in Africa want an anthology that includes all the works of Wole Soyinka.
