The speaker in "Birches" compares the boy's climbing to a forest full of spiderwebs.

The speaker in "Birches" compares the boy's climbing to girls drying their hair, sweeping up broken glass, a forest full of spiderwebs, and filling a cup to the top.

To determine the correct comparison in the poem "Birches" by Robert Frost, we need to examine the text. In the poem, the speaker describes watching a boy climbing up and swinging down birch trees. In one particular section, the speaker states:

"So was I once myself a swinger of birches.
And so I dream of going back to be.
It's when I'm weary of considerations,
And life is too much like a pathless wood
Where your face burns and tickles with the cobwebs
Broken across it, and one eye is weeping
From a twig's having lashed across it open."

From this context, we can conclude that the speaker compares the boy's climbing to a forest full of spiderwebs. The cobwebs mentioned in the lines represent the obstacles and challenges that the boy encounters while climbing. The image of spiderwebs suggests a sense of entanglement and difficulty, similar to the boy's experience in the birch trees.

Therefore, the correct answer is "a forest full of spiderwebs."
