Hi!
In 1981, the term 4GL was actually used to refer to languages which were <em>non-procedural. </em>A procedural language does not possess <em>object-oriented </em>capabilities. 4GL's often times have OOP properties, so I believe the answer to this question is going to be <em>false. </em>=)
Application I think because software used to create a program is called application software I'm not entirely sure about that though
You can just put “/“ to represent dividing
