4. My Mother bought 5 bunch of flower to decorate our lounge room.

- Underlined nouns: *bunch* and *flower*
- Rule:
- *bunch* → *bunches* (ends in ch → add -es)
- *flower* → *flowers* (regular → add -s)
- ✔ Corrected sentence:
My Mother bought 5 bunches of flowers to decorate our lounge room.

> 💡 Note: “bunch” becomes “bunches” because it ends in “ch”, which requires “-es” for plural. “Flower” is regular.

5. All the adorable puppy were playing at the park with the child.

- Underlined nouns: *puppy* and *child*
- Rule:
- *puppy* → *puppies* (ends in y after consonant → change y to i + es)
- *child* → *children* (irregular plural)
- ✔ Corrected sentence:
All the adorable puppies were playing at the park with the children.

> 💡 Tip: “child → children” is one of the most common irregular plurals. “Puppy → puppies” follows the “y-to-i” rule.

- *crib* → *cribs* (regular → add -s)
- ✔ Corrected sentence:
The babies were crying loudly in their cribs because they were hungry.

> 💡 Also note: The verb “were” already agrees with plural subject — so changing “baby” to “babies” fixes the subject-verb agreement too.
