TOEFL integrated writing: Chevalier de Seingalt

This material addresses the question of the accuracy of the memoir written by Chevalier de Seingalt. The reading passage suggests that some aspects of the book are controversial. The lecturer, on the other hand, refutes this information by stating that the memoir is a reliable historical source.
To begin with, the reading passage highlights that the Chevalier wrongfully considered as a rich person irregardless of the fact that he borrowed money from a merchant. Meanwhile, the professor casts doubt on this and argues that the Chevalier might have needed cash untill his property was sold, and, therefore, he cannot be viewed as a poor person.
Additionally, the article posits that the records related to the conversations between the Chevalier and Volter could not have been reflected accurately since many years had passed from the time they had met. However, the professor advocates a different approach and provides the following details. Namely, she mentions that there is evidence that Chevalier was wrighting down the talks with Voltaire immediately after having them, and later he used that records to write the memoir.
Finally, the author invites attention to the fact that Chevalier could not have escaped from the prison in Venice in the way he described in the book; by making a hole in the ceiling. This goes counter to the information in the listening passage, according to which, official documents were found that contained an indication of the fact that the ceiling after the Chevalier's escape needed repair.
