After reading this passage, Jill infers that the character Opa did not understand English very well:

After years of just scraping by in his new homeland, Opa wanted something more. He wanted a better chance at the American Dream. On the day in question, Opa had his first grasp at that better chance: an interview for a full-time position as a music teacher in a swanky private school. Then he got lost. To this day, he insists the school gave him the wrong directions, but my guess is he misunderstood the directions given to him—a familiar habit of his. At any rate, Grandma noticed him wandering lost in her neighborhood. By the time he passed her house for the fifth time, she decided to intervene. They married 18 months later.

What evidence could be added to the passage to support Jill’s inference?

A. the name of Grandma’s neighborhood
B. a quotation from Opa about his experience
C. the text of the directions that Opa was given
D. a brief conversation between Grandma and Opa
