Which consequence resulted from lowered humidity during medieval parchment production?

💡 Explanation

Lowered humidity decreased fibril adhesion because water molecules mediate hydrogen bonds within collagen via capillary action bonding; therefore parchment fibers became brittle and susceptible to damage, rather than remaining flexible due to sustained fiber proximity.
