In September 1999, the Mars Climate Orbiter crashed onto the surface of Mars due to a calculation error. (It even happens to NASA scientists!) There was a miscommunication between one team of engineers that was working in English units of pounds per second of thrust, and the rest of the NASA team that was working in metric units of newtons per second of thrust. When the lander approached Mars to go into orbit, it thought the English units were metric units, misjudged how fast it was going, entered the atmosphere too soon, and crashed. Write a real-world problem that gives two different rates that must be converted to unit rates and then compared.

"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
