    A) government spending by $200 billion

    Explanation:

    The government spending multiplier is calculated by dividing 1 by marginal propensity to save.

    marginal propensity to save (MPS) = 1 - MPC = 1 - 0.8 = 0.2

    government multiplier = 1 / 0.2 = 5

    since we need to reduce aggregate demand by $1,000 billion, then we need to decrease spending by:

    spending decrease x multiplier = $1,000 billion

    spending decrease = $1,000 billion / 5 = $200 billion
