Final answer:
Mr. Tushman's character, based on the interaction with August, is best described as kind, although the specific textual evidence provided does not pertain to him.
Step-by-step explanation:
Based on Mr. Tushman's first encounter with August in the text, the most fitting adjective to describe him would be kind. This can be inferred from how the character is introduced and interacts with others in the narrative. The presented textual evidence does not provide sufficient detail about Mr. Tushman, and thus, it would not be accurate to describe him as intimidating, strict, or friendly without the specific text from 'Wonder' by R.J. Palacio. In literature, it is key to refer to the actual text in the book being studied to support character descriptions.
