There are many structural and thematic similarities between Piers Plowman by Langland (1330-1400) and House of Fame by Chaucer (1342-1400), two Middle English poems relating dream visions. Some critics have argued that because a number of the shared elements are uncommon in Middle English poetry, and because Langland’s poem probably predates Chaucer’s by a few years, Chaucer was most likely influenced by Piers Plowman when writing House of Fame.
Which of the following, if true, most seriously weakens the critics’ argument?
A. Piers Plowman is one of Langland’s major works, whereas House of Fame is a minor work of Chaucer’s.
B. House of Fame survives in only three manuscript copies, substantially fewer than the number of manuscript copies that exist of Piers Plowman.
C. Because Piers Plowman became a well-known work in its day, it is likely that the similarities between it and House of Fame were detected by many of the people who read House of Fame soon after Chaucer wrote it.
D. Many of the themes and structures of Piers Plowman are also found in Latin, Italian, French works with which Chaucer could well have been familiar.
E. There is no evidence that Chaucer and Langland ever met or that they corresponded with each other about literary topics.
Conclusion -> Chaucer was most likely influenced by Piers Plowman(written by Langland) when writing House of Fame.
Now i have to weaken by saying it wasn't the influence of Langland's book but something else is the reason for that influence.
I thought on these lines , they could be working together on some project, something else influenced Langland's book.
A. Piers Plowman is one of Langland’s major works, whereas House of Fame is a minor work of Chaucer’s.
This is nowhere questioning the conclusion, Irrelevant
B. House of Fame survives in only three manuscript copies, substantially fewer than the number of manuscript copies that exist of Piers Plowman.
There is no relationship between survival of manuscripts and influence.
C. Because Piers Plowman became a well-known work in its day, it is likely that the similarities between it and House of Fame were detected by many of the people who read House of Fame soon after Chaucer wrote it.
this is a mild strengthener.
D. Many of the themes and structures of Piers Plowman are also found in Latin, Italian, French works with which Chaucer could well have been familiar.
This correctly gives us the different reason for the influence.
E. There is no evidence that Chaucer and Langland ever met or that they corresponded with each other about literary topics
Meeting has no relationship between getting and not getting influenced by somebody's work.
