Read the poem given below and answer the questions that follow by selecting the correct/most appropriate options :

I think that I shall never see
A poem lovely as a tree. A tree whose hungry mouth is prest
Against the earth’s sweet flowing breast; A tree that looks at God all day,
And lifts her leafy arms to pray; A tree that may in Summer wear
A nest of robins in her hair; Upon whose bosom snow has lain;
Who intimately lives with rain. Poems are made by fools like me,
But only God can make a tree.

The word, ‘mouth’ in line 3 refers to the ________ of the tree.

The correct answer is roots.

Step-by-step Explanation:

1. Analyze the Poem's Context:
In lines 3 and 4 of the poem, the speaker describes a tree as:
"A tree whose hungry mouth is prest
Against the earth’s sweet flowing breast;"

2. Understand the Metaphor:
The poem uses personification to describe the tree. The phrase "hungry mouth is prest against the earth’s sweet flowing breast" metaphorically represents how the tree absorbs water, nutrients, and nourishment directly from the earth/soil.

3. Identify the Botanical Part:
The part of a tree that is physically situated in the ground/soil and drinks water or absorbs nourishment from the earth is the roots. Therefore, the word "mouth" refers to the tree's roots.
