 * Response area contains four response items. One item contains icon and text,

 * (e.g. unchecked icon and "Accept" as a text) except the first topic line that

 * doesn't have the icon. Topic item might have text in two lines depending on

 * the text length and screen orientation. Item is highlighted by drawing svg graphic
