Question

Which line from Chaucer’s “General Prologue" to The Canterbury Tales is a reference to the feudal social structure of medieval England?
Full worthy was he in his liege-lord's war,
And therein had he ridden (none more far)
As well in Christendom as heathenesse,
And honoured everywhere for worthiness.
At Alexandria, he, when it was won;

Answer 1

The answer is  A: Full worthy was he in his liege-lord's war. The word liege means 1. loyal; faithful. 2. a feudal superior. The Feudal System was a system in the Middle Ages by which lesser lords, called vassals, held in trust large landed estates from more important lords, being bound in return to fight for these lords in times of war. Feudal was the loyalty of a vassal to his lord.

Answer 2

I'd say the answer is the first line, 'Full worthy was he in his liege-lord's war', because a liege-lord was a title in the feudal society, a person of great wealth who had many servants and a lot of land.
