Read the paragraph from Ivanhoe.
"Rebecca," said Ivanhoe, "thou hast painted a hero; surely they rest but to refresh their force, or to
provide the means of crossing the moat-Under such a leader as thou hast spoken this knight to be, there
are no craven fears, no cold-blooded delays, no yielding up a gallant emprise; since the difficulties which
render it arduous render it also glorious. I swear by the honor of my house-I vow by the name of my
bright lady-love, I would endure ten years' captivity to fight one day by that good knight's side in such a
quarrel as this!"
In which sentence is the word arduous used in a similar manner as in the paragraph?
