**Title: Understanding Line Integrals in Vector Fields**

**Instructions:**
Determine whether the line integral of each vector field (in blue) along the oriented path (in red) is positive, negative, or zero.

**Description of Diagrams:**

1. **Top Left Diagram:**
   - **Vector Field:** Blue arrows pointing radially outward.
   - **Path:** Red square oriented clockwise.
   - **Question:** Choose if the integral is positive, negative, or zero.

2. **Top Middle Diagram:**
   - **Vector Field:** Blue arrows swirling from the outside inwards in a counterclockwise direction.
   - **Path:** Red spiral oriented clockwise.
   - **Question:** Choose if the integral is positive, negative, or zero.

3. **Top Right Diagram:**
   - **Vector Field:** Blue arrows pointing radially outward.
   - **Path:** Red triangle oriented clockwise.
   - **Question:** Choose if the integral is positive, negative, or zero.

4. **Bottom Left Diagram:**
   - **Vector Field:** Blue arrows swirling from the inside outwards in a counterclockwise direction.
   - **Path:** Red spiral oriented clockwise.
   - **Question:** Choose if the integral is positive, negative, or zero.

5. **Bottom Middle Diagram:**
   - **Vector Field:** Blue arrows uniformly pointing to the right.
   - **Path:** Red line segment oriented right.
   - **Question:** Choose if the integral is positive, negative, or zero.

6. **Bottom Right Diagram:**
   - **Vector Field:** Blue arrows uniformly pointing to the right.
   - **Path:** Red semicircle oriented clockwise.
   - **Question:** Choose if the integral is positive, negative, or zero.

**Educational Goal:**
This exercise helps in understanding how vector fields interact with paths. By analyzing the orientation of the path relative to the direction of the vector field, determine the sign of the line integral.
