Final answer:
Without specific context, it's impossible to accurately determine who Danglars insisted was responsible for the scandal. Generally, Danglars is known from Alexandre Dumas's 'The Count of Monte Cristo' where he is behind the scandal of falsely accusing Edmond Dantès.
Step-by-step explanation:
In the context of the question about who Danglars insisted was responsible for the scandal, it is important to identify the specific work of literature and scandal being referred to. However, since the question does not provide sufficient information to pinpoint the exact source material, it is not possible to give a definitive answer.
The characters mentioned (Nora, Danglars, Dupin, Gil-Dong, Émile Zola, and Alcée Laballière) come from different literary works. Without context, we cannot attribute the scandal to any particular character or incident linked to Danglars.
However, Danglars is a character in Alexandre Dumas's The Count of Monte Cristo, and in that novel, he is responsible for creating a scandal by falsely accusing Edmond Dantès of being a Bonapartist traitor, leading to Dantès's imprisonment. This is only an educated guess based on the information typically associated with Danglars.
