The lines which demonstrate a manner of speaking appropriate are lines 408 to 412.
Answer: Option 4.
Step-by-step explanation:
The context has been taken from "The Nun's Priest's Tale". It is a narrative poem which was composed in the early time period of 1390s. This poem is a mock epic and beast fable. This poem is based on an incident that took place in the Reynard cycle. The poet of this poem is Geoffrey Chaucer who was a poet of the Middle English.
The lines in the poem which demonstrate a manner of speaking more appropriate to a far more serious and tragic content are the lines from 408 to 412 out of the 626 lines in the poem.
