A passage on museum replicas states that replicas make originals less important only if the record also shows that students handled copies to compare tool marks that the original display hid. The author later says that even when that condition is present, replicas can protect originals while expanding study. The passage never says the condition by itself is sufficient. First-pass status: An inference question is narrowed to two choices, one treating the condition as necessary and one treating it as sufficient. A detail question about the author's later point has been answered. The student expects the condition check to take less than a minute and has 10 minutes left.
