Task: Question Generation
Input (English): Background Paragraph: A screw is a simple machine that consists of an inclined plane wrapped around a central cylinder. No doubt you are familiar with screws like the wood screw in the left-hand side of the Figure below . The cap of the bottle pictured on the right is another example of a screw. Screws move objects to a greater depth (or higher elevation) by increasing the force applied to the screw. Many screws are used to hold things together, such as two pieces of wood or a screw cap and bottle. When you use a screw, you apply force to turn the inclined plane. The screw, in turn, applies greater force to the object, such as the wood or bottle top. You can watch an animation of a turning screw at the following URL. 
Story: At a new years party Mary brought an expensive bottle of champagne for the host. Just before midnight she goes and finds a corkscrew to open the bottle. She places the corkscrew on the cork and begins twisting it, making the corkscrew push itself into the cork so she can open the bottle easier.
Output (English): Will the force applied to the corkscrew's inclined plane have increased or decreased after Mary finishes twisting it?
