When Hana took her first long reading test, she blamed every pause on vocabulary. Her record showed a different pattern. In the first passage, she knew the key words but attached a relative clause to the wrong noun. In the second, she understood each sentence but could not locate the sentence that supported the correct option. In the third, she spent nearly three minutes comparing two choices after she had stopped finding new evidence. Her teacher labeled these pauses structure, evidence, and pacing rather than calling all three vocabulary problems. The next day, Hana recovered the main clause in the first passage without help. Three days later, however, she made the same attachment error in a new sentence. That result showed that remembering an explanation and transferring a reading operation were different achievements. Her winter plan therefore began with short structure practice and delayed retests, while vocabulary review continued only for words that had actually blocked meaning. The diagnosis did not predict a future school grade; it identified the first operation that needed repair.
