Q1  15
Q1 15

Question 1: The doctors discussed two medical ___ at the hospital meeting.

Question 1 options
'Crises' is correct because 'crisis' is an irregular noun ending in '-is', and its plural is formed by changing '-is' to '-es'. 'Crisises' is not a valid English word. 'Crisis' is singular. 'Crisiss' is not a real form.
Q2 15

Question 2: There were three economic ___ in that country during the last decade.

Question 2 options
'Crises' is correct because when a noun ends in '-is', the plural is formed by replacing '-is' with '-es'. 'Crisises' incorrectly adds '-es' to the whole word. 'Crisis' is singular only. 'Crisi' is not an English word.
Q3 15

Question 3: The plural of 'crisis' is formed by adding '-es' to the end of the word, making 'crisises'.

Question 3 options
False because 'crisis' ends in '-is', and the rule for nouns ending in '-is' is to replace '-is' with '-es', giving 'crises' — not to add '-es' to the whole word.
Q4 15

Question 4: When would you use the word 'crises' instead of 'crisis'?

Question 4 options
'Crises' is used when referring to more than one crisis. It is the plural form of 'crisis', an irregular noun. The other options misuse the term by applying it to single events or incorrect grammatical contexts.
Q5 15

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

Question 5 options
  • faced
  • The country
  • last year
  • two major crises

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

The correct order is 'The country faced two major crises last year' because 'crises' is the plural of 'crisis' (irregular noun ending in '-is' → '-es'), and this subject-verb-object structure with a time phrase at the end is standard English.
Q6 15

Question 6: Which sentence is grammatically correct?

Question 6 options
'The government handled both crises well' is correct because 'crises' is the proper plural of 'crisis'. 'Crisises' is not a valid English word. 'Crisis' is singular and cannot follow 'both'. 'Crisiss' does not exist in English.
Q7 15

Question 7: Teacher: 'What is the correct plural of crisis?' Student: 'I think it is ___.' Teacher: 'That's right!'

Question 7 options
'Crises' is the only correct plural form of 'crisis'. The teacher confirms the student's answer, so only the grammatically correct plural can fit. 'Crisises', 'crisiss', and 'crisis' are all incorrect or singular forms.
Q8 15

Question 8: Which sentence correctly uses the plural form of an '-is' noun, NOT the incorrect regular plural?

Question 8 options
'Scientists studied several hypotheses about climate change' is correct because 'hypothesis' ends in '-is' and its plural is 'hypotheses', not 'hypothesises'. This mirrors the rule that makes 'crises' (not 'crisises') the correct plural of 'crisis'.
Q9 15

Question 9: Put the words in the correct order:

Question 9 options
  • experienced
  • Many families
  • during that period
  • financial crises

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

The correct order is 'Many families experienced financial crises during that period' because 'crises' is the irregular plural of 'crisis', replacing '-is' with '-es', and the sentence follows standard subject-verb-object word order.
Q10 15

Question 10: The news report said the region had faced multiple ___. Which option best completes this sentence?

Question 10 options
'Crises' is correct because it is the standard plural of the irregular noun 'crisis'. The sentence requires a plural noun after 'multiple'. 'Crisises' is not a valid word. 'Crisis' is singular. 'Crisi' does not exist in English.
Q11 15

Question 11: Which statement about nouns ending in '-is' is true?

Question 11 options
Nouns ending in '-is' form their plural by replacing '-is' with '-es', not by adding '-es' to the whole word. This is an irregular pattern, which is why 'crisis' becomes 'crises', not 'crisises'.
Q12 15

Question 12: Rewrite in the plural: 'The city experienced a crisis.' → 'The cities experienced ___.'

Question 12 options
'Crises' correctly completes the transformation because it is the irregular plural of 'crisis', formed by replacing '-is' with '-es'. 'Crisises' is not a valid word. 'Crisis' remains singular. 'A crises' is incorrect because 'a' cannot precede a plural noun.
Q13 15

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

Question 13 options
There are two crises in the news today.
The research had three different bases.
She submitted two theses to the university.
The lab completed several analyses of the data.
Irregular plural: crisis → crises
Irregular plural: analysis → analyses
Irregular plural: thesis → theses
Irregular plural: basis → bases

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

Nouns ending in '-is' form irregular plurals by replacing '-is' with '-es'. This applies to crisis→crises, basis→bases, thesis→theses, and analysis→analyses.
Q14 15

Question 14: Some nouns ending in '-is' can have two accepted plural forms in English.

Question 14 options
True because some nouns ending in '-is', such as 'mantis', can form their plural in two ways: 'mantises' (by adding '-es') or 'mantes' (a classical form). However, 'crisis' has only one correct plural: 'crises'.
Q15 15

Question 15: Which sentence uses the plural of 'crisis' in the most natural and formally correct way?

Question 15 options
'The report described the crises affecting three different regions' is the most natural and formally correct use. 'Crises' is the standard irregular plural of 'crisis', appropriate in both formal writing and spoken English. The other options use incorrect plural forms.
