Explanation:

The sale of marketable securities at a loss gives rise to a realized loss.  This is recorded in the non-operating section of the income statement after the operating section.  Items 2 and 3 are recorded in the operating section of the income statement, as they relate to the entity's normal operations.  Item 4 refers to an unrealized gain.  This is recorded in the other comprehensive income section just as unrealized losses.  The other comprehensive income section shows the comprehensive income and expenses, which refer to changes in equity that originate from non-operating sources.
