1. In the middle of the page, draw two vertical lines an inch long, an inch apart, and that are parallel to each other.

2. About a half inch below the lines, draw a half-inch horizontal line that is centered between the lines.
3. Draw a line from the bottom of the left vertical line and connect it to the left end of the horizontal line.
4. Draw a line from the bottom of the right vertical line and connect it to the right end of the horizontal line.
5. From the top of the left vertical line draw a large arc and connect it to the top of the right vertical line.

To draw the requested picture step by step, follow these instructions:

Step 1:
- Start by taking a blank sheet of paper and a ruler.
- Place the ruler vertically on the paper, in the middle of the page.
- Draw a vertical line that is 1 inch long using the ruler.
- Leave a small gap of 1 inch between the two vertical lines.
- Draw a second vertical line, parallel to the first one, also 1 inch long.
- Make sure both lines are straight and parallel to each other.

Step 2:
- Measure a distance of half an inch below the two vertical lines and make a small mark using the ruler.
- Place the ruler horizontally and position it so that the mark is at the center of the ruler.
- Draw a horizontal line, half an inch long, centered on the mark.
- The horizontal line should be perpendicular to the vertical lines.

Step 3:
- Draw a diagonal line from the bottom end of the left vertical line.
- Connect it to the left end of the horizontal line.
- The diagonal line should be slanted towards the left.
- Make sure it extends from the bottom of the vertical line to the left end of the horizontal line.

Step 4:
- Draw a diagonal line from the bottom end of the right vertical line.
- Connect it to the right end of the horizontal line.
- The diagonal line should be slanted towards the right.
- Make sure it extends from the bottom of the vertical line to the right end of the horizontal line.

Step 5:
- Start at the top end of the left vertical line.
- Draw a large arc that curves upwards and to the right.
- Continue the arc until it reaches the top end of the right vertical line.
- The arc should be smooth and symmetrical.
- Make sure it connects the two top ends of the vertical lines.

Congratulations! You have successfully drawn the requested picture step by step.

To follow the instructions and complete the drawing, you will need a ruler, a pencil, and a sheet of paper.

1. Start by placing your ruler vertically on the page at the center. Measure the distance of one inch and make a small mark at the top and bottom of the ruler. This will help you draw two parallel vertical lines that are an inch long and an inch apart from each other.

2. Using your ruler again, measure half an inch below the lines you just drew. Make a small mark in the center at that position. This mark will serve as a starting point for the horizontal line.

3. Connect the bottom of the left vertical line to the left end of the horizontal line. To do this, place the ruler vertically with one end touching the bottom of the left vertical line. Then, move the ruler horizontally until it intersects with the left end of the horizontal line. Draw a straight line connecting these two points.

4. Repeat step 3, but this time connect the bottom of the right vertical line to the right end of the horizontal line. Use the ruler to guide you and draw a straight line.

5. To draw a large arc, start at the top of the left vertical line. Position the tip of your pencil at that point and use your hand to pivot the pencil while maintaining contact with the paper. Move the pencil in a curved motion until it reaches the top of the right vertical line. This will create an arched line that connects the two points.

By following these step-by-step instructions, you should now have a drawing with two parallel vertical lines, a centered horizontal line below them, and a curved arc connecting the tops of the vertical lines.
