What the author of this poem supportive abolitionist movement evidence suggests for dbq4?

In the poem, the author expresses their support for the abolitionist movement by calling for the immediate emancipation of enslaved people and an end to the oppression and violence they face.

For example, the author writes:

```

No longer shall the slave be bound—

Let freedom's light upon him shine;

No longer shall his soul be ground

Beneath oppression's galling chain.

```

These lines clearly and strongly advocate for immediate emancipation. In the first line, the author demands that the slave "be bound no longer," thus expressing the desire to break the literal chains that physically constrain slaves.

In the second line, the author highlights the importance of enlightening the slaves with the "light" of freedom, metaphorically symbolizing their journey from their dark state of bondage to the glorious world of liberty.

Additionally, the use of imagery of "oppression's galling chain" in the third line strongly communicates the author's disapproval of the way enslavers use chains, which represents the oppressive system designed to control enslaved people.
