book-4 L3 & L4: lead topics with sentences, not word lists

Regenerated with a stronger guide rule: never open a part with a
bare-word drill — lead with a sentence-based presentation, cassette
word-drills follow as reinforcement. Also fixed a heard-stimulus
defect (duplicate PROMPT instead of PROMPT+RESPONSE) in the dictation
and demonstrative cloze. Both 100% cassette coverage.
