Answer Question 5 please

**Question 4**

A sketch of an adjustable-height platform used to load and unload freight trucks is shown below. 

**What is the degree-of-freedom of this mechanism?**

*Diagram Description*:  
The diagram shows a side view of a truck near an adjustable-height platform. The platform has a lever and link mechanism that includes a hydraulic actuator, depicted as a piston. The platform is inclined, supported by a lever arm and connecting rods, which make it possible to move the platform up and down.

**Question 5**

For the adjustable platform shown above, are the number of hydraulic actuators sufficient to fully control the motion of this mechanism?

- Yes
- No
