Q1  15
Q1 15

Question 1: There are three ___ playing in the garden.

Question 1 options
'Children' is correct because 'child' forms its plural irregularly as 'children', not by adding -s or -es. 'Childs', 'childes', and 'childrens' are all incorrect plural forms.
Q2 15

Question 2: The dentist said I need to brush my ___ twice a day.

Question 2 options
'Teeth' is correct because 'tooth' forms its irregular plural by changing the vowel sound to 'teeth'. 'Tooths', 'toothes', and 'teeths' are not valid English plural forms.
Q3 15

Question 3: All irregular plural nouns in English are formed by changing the vowel sound of the singular noun.

Question 3 options
False because irregular plurals are formed in several different ways: some change vowel sounds (foot/feet), some use completely different words (person/people), some add unusual endings (child/children), and some stay the same (sheep/sheep).
Q4 15

Question 4: Which situation correctly uses an irregular plural noun?

Question 4 options
'The farmer has ten sheep on his land' is correct because 'sheep' is an irregular plural that does not change form — the singular and plural are identical. The other options use incorrect plural forms for irregular nouns.
Q5 15

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

Question 5 options
  • home.
  • The two
  • heavy bags
  • women
  • carried

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

The correct order is 'The two women carried heavy bags home' because 'women' is the irregular plural of 'woman', and the sentence follows standard subject-verb-object word order.
Q6 15

Question 6: Which sentence is grammatically correct?

Question 6 options
'A family of geese swam across the lake' is correct because 'geese' is the proper irregular plural of 'goose'. 'Gooses', 'goosies', and 'goosen' are not valid English plural forms.
Q7 15

Question 7: Teacher: 'How many ___ are in your class?' Student: 'There are 25 in my class.'

Question 7 options
'People' is correct because it is the irregular plural of 'person'. In this conversational context asking about a count of individuals, 'people' is the only natural and grammatically correct choice. 'Persons' is very formal and rare, while 'peoples' and 'persons-es' are incorrect.
Q8 15

Question 8: Which sentence correctly uses an irregular plural, not a regular plural?

Question 8 options
'The mice ran across the kitchen floor' correctly uses 'mice', the irregular plural of 'mouse', formed by changing the vowel. The other options use 'mouses', 'mousees', or 'mices', which incorrectly apply regular plural rules to an irregular noun.
Q9 15

Question 9: Put the words in the correct order:

Question 9 options
  • the same
  • men
  • office.
  • Both
  • work at

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

The correct order is 'Both men work at the same office' because 'men' is the irregular plural of 'man', and 'both' correctly precedes a plural noun in this structure.
Q10 15

Question 10: The hikers had sore ___ after walking up the mountain all day.

Question 10 options
'Feet' is correct because it is the irregular plural of 'foot', formed by changing the vowel. 'Foots', 'feets', and 'footses' are all incorrect — 'foot' does not follow the regular rule of adding -s.
Q11 15

Question 11: Which statement about irregular plural nouns is true?

Question 11 options
'Some nouns have the same form in both singular and plural' is true — for example, 'sheep', 'deer', and 'fish' do not change in the plural. The other statements describe incorrect or over-generalised rules.
Q12 15

Question 12: Rewrite in the plural: 'The child needs a new coat.' → The ___ need new coats.

Question 12 options
'Children' is correct because it is the irregular plural of 'child'. 'Childs', 'childes', and 'childrens' are all incorrect forms — 'child' does not form its plural by adding -s or -es.
Q13 15

Question 13: Match each sentence to the correct description of how the irregular plural is formed.

Question 13 options
There are five men on the team.
Many people attended the concert.
The children are playing outside.
The farmer counted twenty sheep.
Vowel change plural (man → men)
Completely different word (person → people)
No change singular and plural (sheep → sheep)
Special suffix plural (child → children)

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

Irregular plurals are formed in different ways: vowel change (man/men, foot/feet), completely new word (person/people), special suffix (child/children), and no change (sheep/sheep).
Q14 15

Question 14: The word 'fish' can be used as both the singular and plural form in standard English.

Question 14 options
True because 'fish' is one of several irregular nouns that do not change between singular and plural forms. For example, 'I caught one fish' and 'I caught five fish' are both correct.
Q15 15

Question 15: A wildlife expert is writing a formal report. Which sentence uses the correct plural form?

Question 15 options
'Three deer were spotted near the river' is correct because 'deer' is an irregular noun with no change in the plural form. 'Deers' incorrectly applies a regular plural ending to an irregular noun.
