A Council working group studying qualified-majority voting reform has concluded that reducing the blocking minority threshold from 35% to 28% of EU population would accelerate decision-making. The working group bases this on the observation that under the current threshold, a coalition of just four large Member States can block any proposal. Under the proposed threshold, at least six Member States would need to coordinate to form a blocking minority. Since coordinating six governments is more difficult than coordinating four, legislative gridlock will decrease.
Which of the following is an assumption that is necessary for the working group's conclusion to hold?

Negation test applied: if coordination difficulty is NOT the primary factor determining how frequently blocking minorities form — for example, if ideological alignment or treaty obligations are far more influential — then raising the coordination number from four to six does not necessarily reduce gridlock, and the conclusion fails. Choice A addresses geographic diversity, which is irrelevant to the argument's logic. Choice C introduces motivation for blocking, which the argument does not depend on. Choice D is a factual claim about arithmetic that may or may not be true but is not the logical bridge the argument requires. Choice E introduces democratic legitimacy, which is entirely outside the argument's scope.
