Q1 15

Question 1: Which sentence correctly uses subject-auxiliary inversion to form a yes-no question?

Question 1 options
'Has she finished her report?' is correct because subject-auxiliary inversion places the auxiliary verb 'has' before the subject 'she' to form a yes-no question. The other options either keep declarative word order or use incorrect verb forms.
Q2 15

Question 2: The students were not paying attention. ___ they listening when the teacher explained the rule?

Question 2 options
'Were' is correct because the original sentence uses 'were' as the auxiliary verb, and subject-auxiliary inversion in yes-no questions requires moving this auxiliary before the subject. 'Did', 'Had', and 'Have' do not match the past continuous tense context.
Q3 15

Question 3: In English, subject-auxiliary inversion is used to form yes-no questions by placing the auxiliary verb before the subject.

Question 3 options
True because subject-auxiliary inversion is the standard rule for forming yes-no questions in English: the auxiliary verb moves to a position before the subject, as in 'Is she ready?' rather than 'She is ready?'
Q4 15

Question 4: Why is subject-auxiliary inversion used in the sentence 'Never have I seen such a beautiful painting'?

Question 4 options
'To emphasise a negative expression placed at the front of the sentence' is correct. When a negative adverbial such as 'never' is fronted, subject-auxiliary inversion is required as a grammatical consequence of that fronting.
Q5 15

Question 5: Arrange the words to make a correct sentence:

Question 5 options
  • the secret
  • reveal
  • did
  • she
  • At no time

Drag items or use arrows to arrange them in the correct order.

The correct order is 'At no time did she reveal the secret' because when a negative expression like 'at no time' is fronted, subject-auxiliary inversion is required, placing 'did' before the subject 'she'.
Q6 15

Question 6: Which sentence is grammatically correct?

Question 6 options
'Should you need any help, please call us' is correct because in conditional clauses, 'should' can replace 'if' with subject-auxiliary inversion. The other options use incorrect inversion with non-auxiliary verbs or wrong word order.
Q7 15

Question 7: A student writes: 'Linda wonders what did the manager decide.' A teacher corrects this. Which version is correct?

Question 7 options
'Linda wonders what the manager decided' is correct because subject-auxiliary inversion does not occur in indirect questions. The word order in embedded questions follows the standard declarative pattern: subject before verb.
Q8 15

Question 8: Which sentence correctly uses subject-auxiliary inversion rather than a simple declarative statement?

Question 8 options
'Rarely does he complain about his workload' is correct because it uses subject-auxiliary inversion triggered by the fronted negative adverb 'rarely'. The declarative form would be 'He rarely complains', which does not use inversion.
Q9 15

Question 9: Put the words in the correct order:

Question 9 options
  • they would have met
  • her
  • Had
  • they arrived earlier,

Drag items or use arrows to arrange them in the correct order.

The correct order is 'Had they arrived earlier, they would have met her' because in a counterfactual conditional without 'if', subject-auxiliary inversion places 'had' before the subject 'they', and the conjunction 'if' is omitted.
Q10 15

Question 10: My colleague went to the conference last month, and so ___ I.

Question 10 options
'did' is correct because in elliptical clauses with 'so', subject-auxiliary inversion is required and the auxiliary 'did' replaces the main verb 'went' to show agreement with a past simple action. 'went', 'have', and 'was' do not correctly match the grammatical structure required here.
Q11 15

Question 11: Which statement about subject-auxiliary inversion in wh-questions is true?

Question 11 options
When the wh-word is the subject of the sentence, no inversion takes place — the sentence keeps normal declarative order. For example, 'Who called you?' uses 'who' as subject, so no inversion occurs.
Q12 15

Question 12: Rewrite using subject-auxiliary inversion to replace the 'if' clause: 'If she had read the contract carefully, she would not have signed it.' → ___ the contract carefully, she would not have signed it.

Question 12 options
'Had she read' is correct because when 'if' is omitted from a third conditional clause, subject-auxiliary inversion with 'had' before the subject is required. The other options either retain 'if', use wrong auxiliaries, or maintain declarative word order.
Q13 15

Question 13: Match each sentence to the correct grammar label.

Question 13 options
Were they informed about the decision?
Not only did he lie, but he also refused to apologise.
Were the project to fail, the company would lose funding.
She passed the exam, and so did her brother.
Yes-no question with subject-auxiliary inversion
Fronted negative expression triggering inversion
Elliptical clause with 'so' using inversion
Conditional clause with inversion replacing 'if'

Select an item on the left, then tap its match on the right.

Subject-auxiliary inversion is used in four main contexts: yes-no question formation, wh-questions (non-subject), fronted negative adverbials, and conditional clauses without 'if'.
Q14 15

Question 14: Subject-auxiliary inversion occurs in indirect questions, just as it does in direct questions.

Question 14 options
False because indirect questions follow declarative word order, not inverted order. For example, 'I wonder what she said' is correct, while 'I wonder what did she say' is grammatically incorrect.
Q15 15

Question 15: Which sentence is more appropriate when writing a formal business letter offering assistance?

Question 15 options
'Should you require further information, please do not hesitate to contact us' uses subject-auxiliary inversion in a conditional clause without 'if', which is more formal and appropriate for business writing. 'If you require' is grammatically correct but less formal in register.
