Which detail from the passage is evidence that douglas has
few material possessions while he is enslaved?
mrs. lucretia had told me i must get all the dead skin off
my feet and knees
the people in baltimore were very cleanly, and would
laugh at me if i looked dirty.
the thought of owning a pair of trousers was great
indeed!
i went at it in good earnest, working for the first time with
the hope of reward.

The thought of owning a pair of trousers was great  indeed!

Explanation:

In order to be able to affirm the claim that Douglas has few material possessions, we need to look for a sentence in which he refers to what he owns.

In the first two sentences, he speaks of his looks and hygiene. The last one expresses his hopes for a reward, so, no current possessions yet.

The thought of owning a pair of trousers was great  indeed!

Although it doesn't strike us at first, Douglas speaks of owning a pair of trousers. And he does it in such a way that we reckon that it is probably all he has. It makes him so proud to think he owns a single pair of trousers, as proud as a rich man would have been, speaking of his infinite possessions.
