Final answer:
Evie's statement reveals that the wand is located at the Museum of Cultural History and expresses surprise that their method for locating it is successful.
Step-by-step explanation:
Based on the statement given by Evie, '...Anyway! The wand is at the Museum of Cultural History, 2.3 miles away. Wow, it works!' We can interpret that the correct answer to the student's inquiry is b) The wand is at a museum. Evie's expression, 'Wow, it works!' indicates a sense of satisfaction or surprise that the plan or method used to locate the wand is effective. This suggests that option d) (Evie is surprised the plan is working) is also correct. There is no indication that the location of the wand is unknown or that Evie doubts the wand's power, so options a) and c) are not supported by the text.
