Most likely passage for the test:
His broad clear brow in sunlight glowed,
On burnished hooves his war-horse trode;
From underneath his helmet flowed
His coal-black curls as on he rode,
As he rode down to Camelot.
From the bank and from the river
He flashed into the crystal mirror,
"Tirra lirra," by the river
Sang Sir Lancelot
Context: Based off Elaine from Authurian romances, the Lady of Shalott is this character who has been cursed to never look down at Camelot. So she interacts with the world by instead looking through a mirror at whatever images pass through. Unfortunately, she is tempted to look down upon Camelot as the comely Sir Lancelot passes by. Her fate is sealed by this classic fault of her sex: lust or temptation (the viewpoint of the poem, not the test-taker's opinions). She writes her name on the boat and sails down to Camelot, dying along the way. Lancelot comments that the dead woman has a lovely face.
