The image is a screenshot of a computer screen with a text editor open. The text editor is titled "Combinator Exercise page 48 and 49". The page is divided into two sections. 

On the left side of the screen, there is a text box with the title "Yes this is a combination" and a list of questions below it. The questions are:

1. Yes this is the combination.
2. Not a combination (lesson learned) you have to look at what's passed in to see if it's a combinator.
3. Yes is a free variable.
4. Yes, this is an equation.
5. Not an equation (lessons learned).

At the bottom of the page, there are two bullet points. The first bullet point reads "52" and the second bullet point says "This is normal. Our arguments are stacked within."

The background of the image is blurred, but it appears to be a desk or table with a computer monitor and other office supplies.
