Question

1.) Write the meaning of the "verb" focus in general English.

Answer 1

The verb "focus" means to narrow in on one particular aspect of something. When a person "focuses", they are trying to ignore all of the pieces that do not matter at that moment--whether it is details of a piece of writing or other activities to be done. 

The adjective "potential" refers to something that might be, but is not yet. For example, a "potential employee" would refer to a person a company could hire, but they haven't made a decision yet.
