Final answer:
The shock-headed child among the gooseberry bushes was seen by the people passing by the unfrequented cart-road.
Step-by-step explanation:
The shock-headed child among the gooseberry bushes of the old woman's garden was seen by the people passing by the unfrequented cart-road. This detail indicates that these individuals had the opportunity to observe the child while traveling along a road that was not commonly used, suggesting a certain level of isolation for both the child and her grandmother's hovel.
It's also implied that these passersby had only a casual or distant awareness of Jessie-Mary's existence and her connection to the woman living in the mud-wall hovel, highlighting a lack of community engagement or concern for the child's well-being or heritage.
