Read the excerpt from “Louis Pasteur: Battle with Death.” He found that by letting this tissue stand for a few days it became weak. When a dog received this weak nerve tissue it became sick, yes. But not so sick that it died. The dog got well. And after that, even if injected with the strongest nerve tissue, the dog did not develop rabies. Its body had built up strength against the disease. The dog was “immune.”

The scientist knew that persons bitten by rabid dogs do not show signs of illness until nearly a month later. If resistance could be built up in these people before they showed signs of the disease, perhaps they might not sicken at all! He worked up a course of treatment. It would take fourteen days.

On the first day a dose of a very weak fourteen-day-old nerve tissue was to be given to a person who had been bitten. This was followed on the second day by a thirteen-day-old dose. And so on, until on the last day strong virus was to be given. During this time the person’s body would be building up resistance. Finally, the victim would have so much resistance that he would not get sick.

How do the details in the excerpt support its main idea?

"the children's hour" by henry wadsworth longfellow between the dark and the daylight, when the night is beginning to lower, comes a pause in the day's occupations, that is known as the children's hour. i hear in the chamber above me the patter of little feet, the sound of a door that is opened, and voices soft and sweet. from my study i see in the lamplight, descending the broad hall stair, grave alice, and laughing allegra, and edith with golden hair. a whisper, and then a silence: yet i know by their merry eyes they are plotting and planning together to take me by surprise. a sudden rush from the stairway, a sudden raid from the hall! by three doors left unguarded they enter my castle wall! they climb up into my turret o'er the arms and back of my chair; if i try to escape, they surround me; they seem to be everywhere. they almost devour me with kisses, their arms about me entwine, till i think of the bishop of bingen in his mouse-tower on the rhine! do you think, o blue-eyed banditti, because you have scaled the wall, such an old mustache as i am is not a match for you all! i have you fast in my fortress, and will not let you depart, but put you down into the dungeon in the round-tower of my heart. and there will i keep you forever, yes, forever and a day, till the walls shall crumble to ruin, and moulder in dust away! which literary device does longfellow use most frequently in the poem? a. simile b. metaphor c. repetition d. personification
