Answer:
B. “After some hours had passed, the headteacher said to me: ‘The adjoining recitation-room needs sweeping. Take the broom and sweep it.’”
Step-by-step explanation:
As per the question, Michelle can use the second quotation i.e. 'After some hours...sweep it' as evidence to substantiate the validity of her claim as it shows the readers that non-fiction text narrates the real events and experiences. In her claim, she asserts that how Washington displays the impact of various backgrounds or locations on his life and the words by his headteacher to him for doing the smaller tasks like sweeping would have inspired him to be humble and not consider any task as petty. This would not only support but also justify the claim and hence, option B is the correct answer.
