ANSWER: [a] 23.5°

EXPLANATION: The tropic of cancer is positioned at 23.5° north of the equator, which is because earth is tilted at 23.5 degrees. Earth's rotational axis is an imaginary straight line which runs through north and south pole and earth's actual rotational axis tilt ranges between 22.3 and 24.5 degrees.

QUESTION: The sun is never directly overhead at noon in Urbana, IL
