Final answer:
The evidence that supports the statement 'In our wagon, there was a friend of my father’s, Meir Katz' is that the narrator directly states 'There was a friend of my father’s, Meir Katz.'
Step-by-step explanation:
The evidence that supports the statement 'In our wagon, there was a friend of my father’s, Meir Katz' is d) 'There was a friend of my father’s, Meir Katz.' This statement directly states that there was indeed a friend of the narrator's father named Meir Katz in their wagon. The other options provide additional details about Meir Katz's behavior or role, but d) is the most direct evidence supporting his presence in the wagon.
