Challenge 3: A Character Style Inside a Paragraph — Solution Walkthrough

Steps:
  1. Inside a body paragraph styled "Normal," select a single
     important word.
  2. Home tab > Styles gallery > apply "Strong" (a built-in character
     style).

What changed about the selected word:

Only the selected word's own character-level formatting changed
(Strong typically renders as bold, though its exact appearance is
defined by the style itself, the same way Heading 1's appearance is
defined by its own style rather than hard-coded).

What stayed exactly the same about the rest of the paragraph:

Every other word in the paragraph keeps its existing "Normal"
paragraph style completely untouched — same alignment, same line
spacing, same indentation, same paragraph-level font. The character
style change was scoped precisely to the selected run of text and
nothing beyond it.

Why a character style is the correct tool here, not a paragraph style:

A paragraph style (like Heading 1 or Normal) always applies to an
ENTIRE paragraph at once — there's no way to apply just part of a
paragraph style to a single word within a larger paragraph, since a
paragraph style governs paragraph-level properties (spacing,
indentation, alignment) that don't make sense applied to a fragment
smaller than the whole paragraph. A character style is specifically
built to apply at the scope this task actually needs: one word, or
one short run of text, inside an otherwise unaffected paragraph. Using
a paragraph style here would either fail outright or require awkwardly
splitting the sentence into its own separate paragraph just to isolate
one word — exactly why this chapter introduces character styles as a
genuinely distinct tool from paragraph styles, not just a smaller
version of the same thing.
