Answer

To solve the question "A line ____ be drawn on a paper," we need to understand the properties of a line.

### Step-by-Step Solution:

1. **Understanding a Line**: A line is a straight one-dimensional figure that extends infinitely in both directions. It has no endpoints.

2. **Drawing a Line**: While we can represent a line on paper, we cannot draw it in its entirety because it has no end.

3. **Filling in the Blank**: Given that a line cannot be fully drawn due to its infinite nature, the correct word to fill in the blank is "cannot."

Thus, the complete statement is: "A line cannot be drawn on a paper."
