English grammar exercise focusing on the use of articles with highlighted nouns.

It looks like you've uploaded a language exercise where you're asked to identify the noun in each sentence and then write an antonym (opposite) for that noun. However, based on the format and the example given:

> An- The ladies are carrying the babies.
> (This seems to be a typo or misformatting — likely meant to say: *Antonym:*)

But looking at the structure, it appears the task is to write an antonym of the underlined word in each sentence.

Let’s go through each sentence one by one, identify the underlined noun, and provide its antonym.

---

a. I met the gentleman.

- Underlined word: gentleman
- Antonym: lady (or woman) – but more precisely, "gentleman" refers to a polite man; antonym could be rude person, but if we stick to gender/noun opposites, lady is common.
- However, since "gentleman" is a male, the opposite in gender would be lady.
- But note: "gentleman" implies politeness, so antonym might also be ruffian or villain.
- But in school-level exercises, lady is often expected as the opposite (gender-wise).
- So:
An: lady

---

b. Riya caught the mouse.

- Underlined word: mouse
- Antonym? Mice are small animals. Antonym could be elephant (large vs. small), or cat (natural predator), but not really a true antonym.
- But in terms of size: large animal vs. small animal
- In basic English, antonyms for "mouse" might be giant or elephant.
- But more likely, this is about size: small → large
- So:
An: elephant (as a representative large animal)
Or better: large animal

But perhaps the intended answer is cat, since cat and mouse are opposites in a predator-prey relationship.

However, cat is not a true antonym — it's a related concept.

Alternatively, if the focus is on size, then big animal.

But let's assume the task wants opposite in meaning — so for "mouse" (small), antonym is giant.

But “giant” isn't a noun in the same category.

Wait — maybe the underlined word is mouse, and we need an antonym noun.

So best choice: elephant (as a large animal).

Or: cat (as natural enemy)

But neither is perfect.

Alternatively, if the underlined word is mouse, and we’re thinking about size, then large creature.

But let’s see the pattern.

---

Wait — look at the first example:
> An- The ladies are carrying the babies.

That doesn’t seem right. Maybe it's supposed to be:

> An: The ladies are carrying the babies.
> Then An: (antonym of "babies"?)

But "babies" antonym? Not clear.

Wait — perhaps the instruction is missing.

But based on the format, and the fact that only one word is underlined in each sentence, the task is likely:

> Write an antonym of the underlined word.

So let's re-express:

---

a. I met the gentleman.

- Gentleman = polite man → antonym: rude man or villain
- But in simple terms: lady (if gender-based), or ruffian
- But most likely expected: lady (as opposite gender)

But "gentleman" is not just gender — it's behavior.

Alternative: thief (opposite in morality)

But again, ambiguous.

Perhaps the task is not antonym, but synonym?

No — it says "An-", which likely means "Antonym".

Let’s try another approach.

Wait — look at the first line:

> An- The ladies are carrying the babies.

That seems like it's not the answer, but the sentence itself.

Maybe the task is: Rewrite the sentence using an antonym of the underlined word.

Ah! That makes more sense.

Let’s test that.

For example:

> a. I met the gentleman.
> An: I met the lady. → No, that changes subject.

Better:
> I met the rude man.

But that’s not a direct antonym.

Alternatively:
> I met the villain.

But not ideal.

Wait — perhaps the underlined word is gentleman, and we are to replace it with its antonym in the sentence.

So:

> a. I met the gentleman.
> An: I met the rude man.

But “rude man” is not a single word.

Alternatively, villain or thug.

But let’s look at other sentences.

---

b. Riya caught the mouse.

- If we replace "mouse" with antonym, what is it?
- Mouse = small animal → antonym: elephant?
- But Riya can't catch an elephant.
- Or cat? But cat is predator, not opposite.

Not working.

c. Clean your tooth.

- Tooth → antonym? Toothless? But that’s adjective.
- Or teeth? No — plural.
- Or mouth? No.
- Perhaps jaw? Not antonym.

Wait — maybe the task is not antonym, but plural?

Check:

- tooth → teeth

Yes! That fits.

And “clean your tooth” → “clean your teeth”

Similarly:

- mouse → mice
- book → books
- thief → thieves
- bench → benches

But that’s plural, not antonym.

Wait — look at the first sentence:

> An- The ladies are carrying the babies.

"ladies" and "babies" — both plural nouns.

But no underlined word.

Wait — in the original image, only one word per sentence is underlined.

Let’s list them again:

a. I met the gentleman.
b. Riya caught the mouse.
c. Clean your tooth.
d. You can see the books in the shelf.
e. The policeman is running after the thief.
f. This bench is broken.

Now, notice:

- tooth → teeth (plural)
- mouse → mice (plural)
- shelf → shelves (plural)
- thief → thieves (plural)
- bench → benches (plural)
- gentleman → gentlemen (plural)

Ah! So the task is likely: Write the plural form of the underlined noun.

Because:

- tooth → teeth
- mouse → mice
- shelf → shelves
- thief → thieves
- bench → benches
- gentleman → gentlemen

And the first sentence: "The ladies are carrying the babies." — both already plural.

So probably the task is:

> Write the plural form of the underlined noun.

Let’s confirm:

a. I met the gentleman.

→ An: gentlemen

b. Riya caught the mouse.

→ An: mice

c. Clean your tooth.

→ An: teeth

d. You can see the books in the shelf.

→ An: shelves

e. The policeman is running after the thief.

→ An: thieves

f. This bench is broken.

→ An: benches

Yes — all these are irregular plurals.

And the first sentence may be a hint: "ladies" and "babies" are already plural.

So the task is: Write the plural form of the underlined noun.
