This illusion reveals how our perception of size is influenced by the context in which an object is presented.

Correct Answer
C. 3D object

Explanation
The brain can be tricked into thinking that the Necker Cube is a 3D object. This is because the Necker Cube is a two-dimensional drawing that can be perceived as a three-dimensional object due to its ambiguous nature. The brain tries to make sense of the conflicting visual cues and can interpret the cube as a three-dimensional shape, even though it is actually a flat image.

Aristotle believed that our senses can be trusted, as they provide us with information about the world around us. However, he also recognized that our senses can be easily fooled, leading to false perceptions and misunderstandings. This is because our senses can be influenced by various factors such as illusions, biases, and limitations. Therefore, Aristotle's statement highlights the importance of critical thinking and careful examination of sensory information to avoid being deceived by false perceptions.

What does the Ponzo illusion illustrate context is fundamental for?
- A.
  
  Shapes
- B.
  
  Depth perception
- C.
  
  Object sizes
- D.
  
  Lines
Correct Answer
B. Depth perception

Explanation
The Ponzo illusion is a visual phenomenon that demonstrates how our perception of depth is influenced by surrounding context. In this illusion, two converging lines are drawn over two identical horizontal lines, creating the illusion that the top line is longer than the bottom line. This occurs because our brain interprets the converging lines as indicating distance and assumes that the top line is farther away, leading us to perceive it as larger. Therefore, the Ponzo illusion illustrates that context is fundamental for our perception of depth.
