The object is the main focus to which questions in the question part refer. Temporal objects are objects that span a linear dimension. An example of a temporal object is a recording of any type, such as audio, visual. These objects fill a single dimensional space which is the duration of the play. A key feature of this kind of object is that there is a starting point and an ending point.
Spatial objects are static.
They can be presented on x and y axis, or columns and rows. Some examples include images, graphics, text, etc. When the object does not fit into the provided space, a scroll bar is shown to enable users to scroll the object. The question part consists of a set of questions referring to an object. A single point question is a question which has a reference to a single segment of an object.
