summarize three theories about origin of an old book and the opposite opinions on these theories

While The reading is talking about three theories that determine the stem of Voynich manuscript, the lecture has a different point of view. First, the reasing mentions that the writer of this mysterious manscrip is a physycian called Ascham's. However, the lecture states that a simple physician like him could not write such a manuscript that included powerful information in it. The lecturer also mentions that Ascham's botany book was simple and does not have anything in common with elaborated Voynich manuscript. Second, the readin expresses that the manuscript is made by Edward Kelley in pupose of earning money from rich people of society. This contradicts the lecture which states on Voynich manuscript vast codes are available and writing them needed huge time and work. Edward was a really smart person in tricking people, but people back then were easy to fool, so, he did not need to put a huge effort to write this complex book to defraud nobles and writing an unadorned book would help him to seel his book to others. Third, the passage mentions that since, Wilfrid M. Voynich had enough knowledge about ancient manuscripts, he created this book by himself to sell it to someone. However, the lecture argues that the book was dated by modern technology and its ink and the vellum are 400 years old. Therefore, it is not possible that Voynich had access to a very old vellum to write on it and it is less likely that the book was fake.
