✔ GOAL OF THE TASK:

You are to rewrite the phrases below so that they include a possessive apostrophe, following the example:

> Example:
> *the mango tree of my sister* → my sister’s mango tree

This means you need to convert “of + noun” constructions into possessive form using an apostrophe + s.

📝 Let’s go phrase by phrase:

#### 1. the wrist of the man
→ the man’s wrist

#### 2. the bicycle of the men
→ the men’s bicycle *(plural “men” → add apostrophe after “s”)*

#### 3. the foot of the trees
→ the trees’ foot *(plural “trees” → apostrophe after “s”)*
⚠️ Note: This is grammatically correct but semantically odd — trees don’t have “feet.” But since this is a grammar exercise, we follow the rule.

#### 4. the whiskers of the American
→ the American’s whiskers *(singular “American” → ‘s)*

#### 5. the eyes of the mango tree
→ the mango tree’s eyes *(singular “mango tree” → ‘s)*
Again, metaphorical or poetic — trees don’t have eyes, but for grammar, it’s fine.

#### 6. the ears of the woman
→ the woman’s ears

#### 7. the opinion of my sister
→ my sister’s opinion

#### 8. the branches of the tree
→ the tree’s branches

#### 9. the laughter of the children
→ the children’s laughter *(plural “children” → ‘s after the word)*
