The correct answer is D. Normal speed.
A Python Rake is a type of rake that is used to collect leaves and other debris. It is typically made of metal or plastic and has a long handle with a curved head. The rake is used by dragging it across the ground, which causes the leaves and debris to be lifted up and onto the head of the rake. The user can then collect the leaves and debris by hand or by using a bag or container.
The speed at which a Python Rake is used is not important. The main goal is to collect the leaves and debris, and the speed at which this is done is not a factor. Some people may prefer to use a Python Rake at a slower speed, while others may prefer to use it at a faster speed. The speed at which the rake is used is a matter of personal preference.
The other options are incorrect because they are specific speeds. A Python Rake can be used at any speed, and the speed at which it is used is not important.
