Article: Another objection is that it is not always possible to demonstrate falsehood definitively, especially if one is using statistical criteria to evaluate a null hypothesis. More generally it is not always clear, if evidence contradicts a hypothesis, that this is a sign of flaws in the hypothesis rather than of flaws in the evidence. However, this is a misunderstanding of what Popper's philosophy of science sets out to do. Rather than offering a set of instructions that merely need to be followed diligently to achieve science, Popper makes it clear in The Logic of Scientific Discovery that his belief is that the resolution of conflicts between hypotheses and observations can only be a matter of the collective judgment of scientists, in each individual case.

Question: What kind of criteria frequently used in science complicates the definitiveness of some hypotheses' falsification?
Ans: statistical

Article: Mexico City, being the seat of the powers of the Union, did not belong to any particular state but to all. Therefore, it was the president, representing the federation, who used to designate the head of government of the Federal District, a position which is sometimes presented outside Mexico as the "Mayor" of Mexico City.[citation needed] In the 1980s, given the dramatic increase in population of the previous decades, the inherent political inconsistencies of the system, as well as the dissatisfaction with the inadequate response of the federal government after the 1985 earthquake, residents began to request political and administrative autonomy to manage their local affairs.[citation needed] Some political groups even proposed that the Federal District be converted into the 32nd state of the federation.

Question: If Mexico City was declared a state, how many states would be in the federation?
Ans:
32
