Question 1 · Single choice
Choose one answer.
Had the clinic ___ the warning signs, the outbreak might have been contained.
- recognized
- recognize
- recognizing
- been recognized
Check answers and explanations
- Answer
- recognized
Had the clinic recognized is an inverted third conditional equivalent to If the clinic had recognized.
recognized: Correct: Had the clinic recognized the warning signs...
recognize: The inverted third conditional requires the past participle after had.
recognizing: The -ing form cannot follow had in this perfect conditional.
been recognized: This would make the clinic the receiver of recognition, which does not fit the meaning.

Question 2 · Single choice
Choose one answer.
If she had followed the treatment plan, she ___ healthier now.
- would be
- would have been
- will be
- is
Check answers and explanations
- Answer
- would be
This mixed conditional links an unreal past condition with a present result, so use would be plus the base form.
would be: Correct: she would be healthier now.
would have been: Would have been gives a past result, not the present result now.
will be: Will does not express this unreal mixed condition.
is: The present simple does not show the hypothetical result.
-
Question 3 · Single choice
Choose one answer.
The findings are significant, ___ the sample was relatively small.
- although
- because
- unless
- provided that
Check answers and explanations
- Answer
- although
Although introduces a concessive clause that contrasts the significance with the small sample.
although: Correct: significant, although the sample was relatively small.
because: Because gives a reason rather than a contrast.
unless: Unless introduces a condition and does not fit this meaning.
provided that: Provided that introduces a condition, not the concessive contrast needed here.

Question 4 · Single choice
Choose one answer.
No sooner ___ the vaccine been approved than demand exceeded supply.

- was
Check answers and explanations
- Answer
- had
No sooner triggers inversion, and the past perfect had been approved is followed by than.
had: Correct: No sooner had the vaccine been approved than...
has: The past event requires had, not present perfect has.
did: Did cannot be followed by the past participle been in this structure.
was: Was does not form the required past perfect inversion.
-
Question 5 · Single choice
Choose one answer.
The specialist recommended that the patient ___ a second opinion.

Check answers and explanations
- Answer

After recommend that, formal English can use the mandative subjunctive with the base form seek.
seek: Correct: recommended that the patient seek...
seeks: The third-person -s form is not used in the mandative subjunctive.
sought: The past form changes the intended recommendation structure.
will seek: Will is not used in the mandative that-clause here.
What to review next
After checking an answer, explain the rule in your own words and write a new sentence using the same pattern. Revisit any rules you could not explain.
A focused practice result shows how you did on these tasks. Use several activities across skills to decide what to study next; one practice score does not certify an overall CEFR level.
Before you practise: a worked example
Describe a condition and its possible result.
If it rains, we will stay indoors.
This first conditional example uses the present simple in the if-clause and will in the result clause for a real future possibility.
This teaching example is separate from the scored questions. After your test, compare any mistakes with the explanation and revisit the topic before trying again.
