Can we draw the following hypothesis from the context? 

Context:

How to level a mobile home<br>Remove the skirting (optional on some) from around your home to gain access to the piers on which the supports sit. Begin at the middle of your mobile home to check the level at each pier. Place a long level at the nearest pier to the center and check the bubble in the center of the level; if it is centered, the area is level.

Hypothesis: This instructions are applicable to other types of homes.
