It's hard to write good questions. I listened to some podcast about asking people true/false questions. One question was something like "2025 was the hotest year we have records for". The correct answer supposed to be "True" but my first thought was "we have fossil records of much higher tempatures". The person writing the question used a poor question. Maybe they could fix it by saying "written records" but even then someone might think "some scientist wrote down they found 3 billion year old rocks were the temp was 160f". That would fit as a valid answer to some. Maybe writing "hotest on record since 1800" would fix it but you can still get into details (hotest in specific spot vs hotest average). Even if you add those qualifications the person might have skipped them so rather than them answering "false" meaning they didn't know the answer, it rather means they didn't pay attention to the details. The point being, it's hard to write good questions.
