Shelly was surprised to learn the dwarf planet pluto used to be considered a planet. what would have had to be true for pluto to remain categorized as a planet?

pluto would need to have an atmosphere.
pluto would need to clear the neighborhood of its orbit.
pluto would need to have a larger moon.
pluto would need to have water or ice.

Consider a file currently consisting of 200 blocks. assume that the file control block (and the index block in the case of indexed allocation) is already in memory. calculate how many disk i/o operations are required for contiguous, linked, and indexed (single-level) allocation strategies, for each of the conditions listed below. in the contiguous-allocation case, assume that there is not room to grow at the beginning but there is room to grow at the end. also assume that the block information to be added is stored in memory.
