A researcher designs a test to measure 'critical thinking ability' in college students using 40 multiple-choice questions. Items 1–20 use clear, simple language and straightforward problem-solving scenarios. Items 21–40 use dense academic prose, complex sentence structures, and discipline-specific jargon—but require the same critical thinking skills. After administering the test, the researcher finds that non-native English speakers score ~15 points lower on items 21–40 than items 1–20, while native English speakers show minimal difference. Which statement best describes a validity concern?
