Read the passage. Paragraph 1: A conservation team cleaned a darkened painting to recover the bright colors believed to lie beneath accumulated grime. Paragraph 2: During cleaning, a translucent brown layer dissolved and was initially classified as later varnish. Paragraph 3: Workshop records subsequently described the painter applying a tinted glaze to unify the scene's light. The removed layer was likely part of the intended composition. Paragraph 4: The intervention changed not only the object's appearance but also the evidence available for interpreting the painter's technique. Paragraph 5: The passage uses the case to support reversible testing, staged cleaning, and complete documentation. Restoration is presented as an inquiry that can alter its own source material. Which map most accurately shows how the passage moves from its opening claim through its later developments on painting conservation and lost glaze?
