I want to know the answer to the following question:
Whose two commentaries were incorporated into Virgil's biography by Suetonius?
All the background I'm provided with is that "Although the commentaries no doubt record much factual information about Virgil, some of their evidence can be shown to rely on inferences made from his poetry and allegorizing; thus, Virgil's biographical tradition remains problematic.". Is that enough to answer the question?
Answer: no
