Final answer:
The couples in these narratives discover hidden and surprising secluded places, ranging from mysterious valleys with houses to cleverly designed defenses to protect cliff-dweller communities.
Step-by-step explanation:
In these excerpts from various narratives, the couples find astonishing hidden places in the clefts of the mountains. These secret spots often include unexpected, secluded territories, such as the mysterious valley with over two hundred good houses surrounded by high and inaccessible mountains, which was found behind a movable stone door.
Additionally, in another narrative, the cliff-dwellers had fashioned a balancing stone for defense, ready to dislodge and block the passage to their secluded habitat, indicating yet another hidden and fortified space. In each case, these discoveries signify aspects of wonder, surprise, and sometimes the necessity of survival and protection.
