Question 1a
They only entertain us without providing any real insights.
They reveal underlying complexities in how our brains process visual information.
They are purely results of eye defects.
They can be easily corrected with training.
Question 1b
"Optical illusions have fascinated scientists and artists alike for centuries."
"By understanding how these illusions work, we get a glimpse into the incredible complexity of our perception and the ways our brains can be tricked."
"Our eyes are the first step in this process."
"The neurons in the brain get 'tired' of processing the same input and start to adjust, sharpening perception but also leading to temporary misinterpretations."
Question 2a
Because our eyes are faulty.
Due to the way our brains process visual information.
Because of poor lighting conditions.
Due to the technology used to create images.
Question 2b
It captures light from the environment.
It moves the eyes to adjust focus.
It processes visual information through layers of neurons.
It reflects images directly as they are.
Question 2c
By using color contrast.
By presenting lines of different lengths.
By employing context cues like arrows to interpret depth and distance.
By making objects appear closer than they are.
Question 2d

They demonstrate that perception is a complex process influenced by various factors, making it sometimes inaccurate.
They indicate that visual perception has no link to past experiences.
They reveal that illusions only occur in artificial environments.
Question 3b
Through rapid blinking.
As a result of sensory adaptation and neuron bandwidth limitations.
Because of the brightness of the image.
Due to changes in air pressure.
