review text: The authors provide a positive answer to the first question proposed by \textit{W. Guo} [Linear Algebra Appl. 266, 261--270 (1997; Zbl 0903.15003)] on a nonnegative inverse eigenvalue problem, in the case that the realizing matrix is symmetric nonnegative circulant or left circulant. The authors also show that there exist symmetric realizability criteria, for which Guo's first question has an affirmative answer. Two examples are provided.
