    Why did Naz negate the first condition? Is it because of the either/or rule?

    i thought the word "must" introduced necessary conditions. why is ":must increase productivity 10 percent..." not a necessary condition

    @esther increase productivity 10% is the necessary condition but the reason we are diagramming the way we did is that this is actually an EITHER/OR statement. Either increase 10% or go bankrupt. Hope that helps! Please let us know if you have any other questions.

    Mehran, could you expand on that please? I don't follow how the phrase being an "either/or" statement changes how we write the conditional. Thanks much.

    @rebut I think "either/or" means that the order doesn't matter at all: Either A or B = Either B or A: If Productivity does NOT increase 10% --> Quore will go bankrupt equals If Quore hasn't gone bankrupt --> Productivity must have increased by 10% This is just randomly choosing one of the sides, negating it and making it the sufficient, and letting the other be the necessary. Diagrammed: not 10% Increase --> B or not B --> 10% Increase
