Question

Transcribed Image Text:**Tarski World Exploration**
**Instructions:**
Refer to the Tarski world illustrated below. The domain of all variables consists of all the objects in this world. For each statement, indicate whether it is true or false by analyzing the positions, shapes, and colors of the objects.
**Diagram Key:**
The grid presented contains a structured arrangement of various shapes, identified by individual labels:
- **Shapes**: Triangles, squares, and circles.
- **Colors**: Blue, black, and gray.
- **Labels**: Each shape is labeled with a lowercase letter from 'a' to 'k'.
**Grid Layout:**
- **Top Row**:
- Left to Right: A blue triangle labeled 'a', a black circle labeled 'b'.
- **2nd Row**:
- Left to Right: A blue rectangle labeled 'e' within a square border, a gray circle labeled 'f', a blue triangle labeled 'c', a gray circle labeled 'd'.
- **3rd Row**:
- Left to Right: A blue triangle labeled 'g', a black square labeled 'h', a gray circle labeled 'i'.
- **4th Row**:
- Left to Right: A black square labeled 'j', a gray circle labeled 'k'.
**Analysis and Statement Evaluation:**
Using the provided diagram, examine the relationships and characteristics of the objects to determine the truthfulness of any given statements. Assess their position, shape, and color to draw logical conclusions.

Transcribed Image Text:The image contains a series of logical statements involving geometric objects and their properties. Each statement requires the selection of either "True" or "False."
**Questions:**
(a) There is a triangle \( x \) such that for all circles \( y \) we have \( x \) is above \( y \).
- ∘ True ∘ False
(b) For every object \( x \), there is an object \( y \) such that if \( x \neq y \) then \( x \) and \( y \) have different colors.
- ∘ True ∘ False
(c) There is a circle \( x \) and there is a square \( y \) such that \( x \) and \( y \) have the same color.
- ∘ True ∘ False
(d) For all circles \( x \) and all squares \( y \), there exist a triangle \( z \) such that \( z \) is a different color from \( x \) and \( y \).
- ∘ True ∘ False
