Answer:
A) blunt and polemical
Step-by-step explanation:
In this remark, the author both affirms that children are right to question the material they are expected to learn and criticizes teachers for failing to appreciate the deeper implications of students’ questions. Her tone is blunt (direct and verging on rude) in that she delivers her criticism frankly without any euphemisms or apologies to soften it. Her tone is also polemical (combative) in that she openly challenges those who see children’s questions as illegitimate or insolent. The author’s word choice and syntax (arrangement of words) contributes to this blunt and polemical tone: by describing the children’s questions as not just “legitimate” but “perfectly legitimate” and by piling up several interpretations of the children’s questions that “[do] not occur” to the teachers, the author forcefully emphasizes the extent of the teachers’ misunderstanding.
