Conversion kept only the tape's confirmation pass ("Now check your
sentences...") as RESPONSE clips, so the gap answers were never audible
during the exercise. Add a PROMPT per item carrying the stimulus pass
("Listen and write", ~12-148s of LLA 1C Figure 6): three short sentences
plus the combined sentence, with clips cut from the figure audio and
ASR-verified against the transcript.
