Definition: In this task, you're given a statement and three sentences as choices. Your job is to determine the neutral choice based on your inference from the statement and your commonsense knowledge. The neutral choice is a sentence that neither agrees nor disagrees with the statement. Indicate your answer as '1', '2', or '3', corresponding to the choice number of the selected sentence. If sentence X agrees with sentence Y, one's correctness follows from the other one. If sentence X disagrees with sentence Y, they can not be correct at the same time.
Input: Statement: Their subtlety of colour, liveliness of posture, and strong, lifelike faces record a last remarkable flowering of Byzantine art before its descent into decadence. Choices: 1. The names of many of these Byzantine artists have been forgotten. 2. Byzantine art was already in decline at this point, and the downfall only accelerated from here. 3. Byzantine art went through one last heyday before it fell into decadence.
