Answer
The book is getting higher.
Explanation
## Step 1: The problem describes a situation where a book is lifted above the ground. This action involves work being done on the book, which results in energy transfer.## Step 2: The energy transferred to the book goes into its gravitational potential energy store. This is because the book is being moved against the force of gravity, which requires work to be done.## Step 3: The reason for this energy transfer is not that the book is heating up, moving, getting heavier, or being bent. Instead, it's because the book is getting higher. As the height of the book increases, so does its gravitational potential energy.
