4. which word or words are related to balance?\nprecedent\ncountenance\nequilibrium\nequivalence\n5. which…

Brief Explanations:

• For question 4:
  • "equilibrium" means a state of balance. "precedent" refers to an earlier event or action that is regarded as an example or guide, "countenance" means face or expression, and "equivalence" means equality in value, amount, function, meaning, etc. But "equilibrium" is the most directly related to balance.
• For question 5:
  • "centennial" is related to a 100 - year celebration. "extravaganza" is a large - scale and often spectacular entertainment or event which can be a form of celebration. "precedent" is not related to celebration, and "rudiment" means a fundamental principle or skill.
• For question 6:
  • "bogus" means not genuine or fake. "gratuitous" means done without good reason; uncalled for. "unremitting" means not ceasing; continuous. "spurious" means not being what it purports to be; false or fake.

Answer:

4. equilibrium
5. centennial, extravaganza
