✔ Explanation:

The superlative form of an adjective is used to compare three or more things and show which one has the highest degree of a quality. It usually ends in "-est" for short adjectives (one or two syllables) or uses "most" before longer adjectives (three or more syllables). Sometimes, irregular forms are used (like “best” or “worst”).

Let’s go through each sentence:

---

1. Your pet ran ________ (fast) of any pet in the race.
→ *Fast* is a one-syllable adjective → add “-est” → fastest
✔ *Your pet ran fastest...*

---

2. Joe is ________ boy in the class. (smart)
→ *Smart* is a one-syllable adjective → add “-est” → smartest
⚠️ But we need the article “the” before the superlative when it modifies a noun directly.
✔ *Joe is the smartest boy...*

---

3. John is the ________ music teacher in my school. (good)
→ *Good* is irregular → its superlative is best
✔ *John is the best music teacher...*

---

4. Which is ________ language of all to learn? (better)
→ *Better* is the comparative of *good*. The superlative of *good* is best.
✔ *Which is the best language...* (again, “the” is needed)

---

5. Which is the (fast) ________ bird in the world?
→ *Fast* → fastest (same as #1)
✔ *...the fastest bird...*

---

6. Which is the (small) ________ bird in the world?
→ *Small* is one-syllable → smallest
✔ *...the smallest bird...*

---

7. He is (bad) ________ employee in the company.
→ *Bad* is irregular → superlative is worst
✔ *He is the worst employee...* (add “the”)

---

8. My project was ________ (good) in class.
→ *Good* → best
✔ *My project was the best in class.*

---

9. She is ________ (beautiful) girl I ever met.
→ *Beautiful* has 3 syllables → use “most” → most beautiful
✔ *She is the most beautiful girl...* (add “the”)

---

10. Lina bought ________ (expensive) cakes.
→ *Expensive* has 3 syllables → use “most” → most expensive
✔ *Lina bought the most expensive cakes.* (add “the”)

---

📝 Final Tip:

Always remember to include “the” before the superlative form when it’s used before a noun (e.g., *the smartest boy*, *the most expensive cakes*). This is a common mistake!
