Choose the correct one-word substitute for: 'A person who supports change'.

Correct — C. A reformer is a person who works for change, especially to improve a law, institution or practice. The word is reform + -er, one who reforms.

That matches 'A person who supports change' directly, adding nothing the definition lacks.

Reformer → option (c).

Why the others are wrong

• (a)
  Conservative — A conservative prefers traditional ways and is wary of change. That is the opposite of the definition.
• (b)
  Radical — A radical wants change that goes to the root (Latin radix), thorough and often extreme. The definition says only 'supports change', with no degree, which fits reformer.
• (d)
  Constitutionalist — A constitutionalist supports constitutional government or keeps to a constitution. The word says nothing about favouring change.

A one-word substitute item gives a definition and asks for the word that says the same. The best fit matches the definition without adding to it.

Here 'supports change' is the whole definition. Reformer says exactly that.

Radical says more (sweeping change), conservative says the opposite, and constitutionalist is about a constitution, not change.

Key facts

• Reformer = a person who works to bring about change or improvement.
• Radical = a person who wants thorough or complete change (Latin radix, 'root').
• Conservative = a person averse to change, holding to tradition.
• Constitutionalist = a supporter of constitutional government.

Common traps

• Choosing Radical because it also involves change, without noticing it adds thorough or extreme change.
• Choosing Constitutionalist because it sounds political, though it says nothing about change.
