What is the most likely purpose of the following lines? "Half sunk, a shattered visage lies, whose frown,
And wrinkled lip, and sneer of cold command..."

to show that ancient sculptors were superior to modern ones in their ability to capture the "passions"
to emphasize the desolate nature of the desert
to describe the disposition of the person the statue portrays
to show that Ozymandias was a weak leader
none of these

to describe the disposition of the person the statue portrays

Explanation:

These are lines from the poem, ''Ozymandias'' by Percy Bysshe Shelley which speaks of a statue of Ozymandias that has now fallen with the two legs being the only remaining standing feature and the head next to them, half buried in sand.

The lines above relate to the features and expression on the face of the statue and serve to describe the disposition of Ozymandias who, judging by the statue, have a commanding expression about him.

"the sandy walls seemed to collapse in on themselves"

and

"the bloodshot waters seemed to have no bottom"

i would just say something like,

i need to go outside owner to pee, hold on owner let me mark this tree. i'm thirsty now "starts drinking water" now i am tired. what are you eating owner can i have some, you can't refuse my cute puppy eyes.

just make sure you write that in your own words that way you don't get in trouble.
