Based on the excerpt, what will readers most likely infer about Grampa? He is accepting of his grandson's ignorance. He is irritated by his grandson's impatience. He believes he will not be able to save all the toads. He believes his grandson should not talk back.

A). He is accepting of his grandson's ignorance.

Explanation:

'Birdfoot's Grampa' authored by Joseph Bruchac primarily discusses the significance of all life and living selflessly.

In the given excerpt from the poem, the readers can deduce that Grampa displays an 'accepting attitude towards his grandson's impatience and ignorance.' This embracing and unified nature of Grampa is reflected through 'his smile' which connotes the theme of the poem i. e. 'accept every element of life and living it generously.' Thus, option A is the correct answer.
