If you knew that basement membrane disruption prevents restoration of normal tissue (repeat from another NBME), then you missed this because you didn't know what "preclude" means.

Missing questions I miss due to lack of vocab and grammar, you love to see it

Correct me if I'm wrong. But I think both types of Pneumocytes sit in the basement membrane. Damage to Type 2 results in an inability to restore lung tissue (they regenerate 1 and increase surfactant) whereas type 1 is used for gas diffusion. So if the BM with the type 2 pneumocystis is damaged, no restoration. I didn't pay much attention to preclude though lol...
