Correct Answer: D

Rationale: The word 'disconfirmed' can be understood by breaking down 'disconfirm,' where 'dis' indicates 'not' and 'confirm' means 'to prove.' Therefore, 'disconfirmed' means 'not proven,' which aligns with the meaning of 'disproven.' In the given passage, it is mentioned that evidence can disprove a hypothesis, not necessarily prove it. This supports the synonymity between 'disconfirmed' and 'disproven.' Choice A ('proven') is incorrect because 'proven' is the opposite of 'disconfirmed.' Choice B ('dissipated') is incorrect as it means to disappear or scatter, not related to disproving a hypothesis. Choice C ('distilled') is incorrect as it means to purify a liquid through heating and cooling, not related to proving or disproving hypotheses.

Rationale: The main idea of the passage is that studying a foreign language should be a compulsory requirement for high school graduation. This is emphasized due to its increasing importance for the global economy, college acceptance rates, and job market competitiveness. The passage argues for states to amend their requirements to reflect this necessity, highlighting the benefits of studying a foreign language. Choice A is incorrect because while the passage mentions job market competitiveness, the main focus is on the requirement for high school graduation. Choice C is incorrect as while understanding other cultures is a benefit of studying a foreign language, it is not the primary message of the passage. Choice D is incorrect as the passage does not solely focus on the necessity of studying a foreign language for college acceptance; rather, it advocates for its inclusion as a high school graduation requirement.
