Which two passages in this excerpt from the death of ivan illych does leo tolstoy use to suggest that ivan ilych feels like his life is slipping away from him? "what's the use? it makes no difference," he said to himself, staring with wide-open eyes into the darkness. "death. yes, death. and none of them knows or wishes to know it, and they have no pity for me. now they are playing." (he heard through the door the distant sound of a song and its accompaniment.) "it's all the same to them, but they will die too! fools! i first, and they later, but it will be the same for them. and now they are merry . . the beasts! " anger choked him and he was agonizingly, unbearably miserable. "it is impossible that all men have been doomed to suffer this awful horror! " he raised himself. "something must be wrong. i must calm myself—must think it all over from the beginning." and he again began thinking. "yes, the beginning of my illness: i knocked my side, but i was still quite well that day and the next. it hurt a little, then rather more. i saw the doctors, then followed despondency and anguish, more doctors, and i drew nearer to the abyss. my strength grew less and i kept coming nearer and nearer, and now i have wasted away and there is no light in my eyes.

Read the passage from animal farm. "that was part of the arrangement! " cried squealer. "jones's shot only grazed him. i could show you this in his own writing, if you were able to read it. the plot was for snowball, at the critical moment, to give the signal for flight and leave the field to the enemy. and he very nearly succeeded—i will even say, comrades, he would have succeeded if it had not been for our heroic leader, comrade napoleon. do you not remember how, just at the moment when jones and his men had got inside the yard, snowball suddenly turned and fled, and many animals followed him? and do you not remember, too, that it was just at that moment, when panic was spreading and all seemed lost, that comrade napoleon sprang forward with a cry of 'death to humanity! ' and sank his teeth in jones's leg? surely you remember that, comrades? " exclaimed squealer, frisking from side to side. now when squealer described the scene so graphically, it seemed to the animals that they did remember it. at any rate, they remembered that at the critical moment of the battle snowball had turned to flee. but boxer was still a little uneasy. how does the characterization of squealer support the author’s purpose? squealer's dramatic accusations draw parallels between him and stalin’s propagandists. squealer's uncertainty shows that he is not a reliable ally of napoleon and is ineffective with messaging. squealer's ability to get the animals to listen to him shows that any animal can rise to be a leader in time. squealer's humble interactions with the animals reflect the importance of equality and cooperation.
