A word you have used your whole life can have one exact meaning in the code, and that meaning is what the question is really asking about.
Most questions people get wrong are not maths. They read a familiar word, used the everyday meaning, and answered a different question than the one on the page.
The pattern is always the same: a question hinges on one word. You think you know what it means. You pick the answer that matches your everyday meaning. The defined meaning is narrower, and the correct answer was the other one. Looking the word up takes fifteen seconds and changes the answer.
Check yourself: A question uses a term you are completely familiar with. Do you still look it up?
Answer: Yes -- especially then.
Familiarity is exactly what makes the trap work. You look up words you do not know anyway; the ones that cost you marks are the ones you were sure about.
