I want to know the answer to the following question:
What is the purpose of the critical apparatus?
All the background I'm provided with is that "The critical apparatus presents the author's work in three parts: first, a list or description of the evidence that the editor used (names of manuscripts, or abbreviations called sigla); second, the editor's analysis of that evidence (sometimes a simple likelihood rating),[citation needed]; and third, a record of rejected variants of the text (often in order of preference).[citation needed]". Is that enough to answer the question?
Answer: yes
