Answer key
  1. You must to finish your vegetables before you can play outside. → False — The modal 'must' is followed directly by the base verb without 'to'.
  2. She has to wear a uniform at her new school. → True — 'Has to' is the correct third-person singular semi-modal for obligation.
  3. Could you help me carry these heavy books, please? → True — 'Could' is correctly used to make a polite request.
  4. We don't must run in the narrow school hallways. → False — To express prohibition, we use 'mustn't', not 'don't must'.
  5. He can plays the piano very well during music class. → False — Modal verbs like 'can' are followed by the base verb without an 's'.
  6. Should I bring my umbrella today because it looks cloudy? → True — 'Should' is correctly used to ask for advice or recommendation.
  7. They will can join us for the birthday party tomorrow. → False — Modals like 'will' and 'can' cannot be combined; use 'will be able to' instead.
  8. You ought to apologize to your friend for breaking his toy. → True — 'Ought to' is a semi-modal used correctly to give advice.
  9. May I go to the restroom, teacher? → True — 'May' is the correct polite modal verb for asking permission.
  10. She cans swim across the deep pool all by herself. → False — Modal verbs never take an 's' in the third-person singular.
  11. Students must not write on the classroom desks. → True — 'Must not' is correctly used to express a strict rule or prohibition.
  12. Do you can speak French with our new classmate? → False — Questions with 'can' start with 'Can you...', not 'Do you can...'.
  13. We might go to the park later if the rain stops. → True — 'Might' is correctly used to show a possibility.
  14. He should studies harder if he wants to pass the test. → False — After the modal 'should', use the base verb 'study' without 'ies'.
  15. Are you able to reach the top shelf to get the blue box? → True — 'Are you able to' is the correct semi-modal question form for ability.
