During a chemistry practical, a student uses a color-based test strip to determine the concentration of metal ions in a solution.
They need to compare the color of the strip to a reference chart displayed on a poster on the classroom wall across the room.
The student struggles to match the color hue of the strip to the poster, and they also cannot read the concentration numbers printed on the poster.
Which statement could explain why?
The student is color blind and long-sighted.
The student is short-sighted.
