Passage with blanks:

> A hot air balloon is an aircraft. It consists of two parts, the basket and the gas bag. The basket is usually made of [ ] and [ ] woven rattan and it is [ ] enough to carry up to thirty adults. The gas bag or balloon is made of nylon which is [ ] but [ ] enough to trap hot air. A hot air balloon can float on air as it is lifted by the [ ] air caused by a burner attached to it. As the burner heats the air, the hot air will move upwards and get trapped in the gas bag.

Step-by-step Analysis & Solution:

1. "The basket is usually made of [ ] and [ ] woven rattan..."
- Rattan is a natural material often used for baskets.
- "Woven rattan" suggests the material is strong and sturdy — both are good candidates.
- But we need two adjectives describing the material.
- "Strong" and "sturdy" both describe durability — likely correct.
- However, "soft" and "light" don’t fit well for structural materials like rattan.
- So: strong and sturdy → best fit.

2. "...and it is [ ] enough to carry up to thirty adults."
- We're talking about the basket’s strength to hold people.
- Best word: sturdy (implies solid and strong).
- "Large" might be tempting, but size isn't the key factor; strength is.
- So: sturdy

3. "The gas bag or balloon is made of nylon which is [ ] but [ ] enough to trap hot air."
- Nylon is light in weight (so it doesn’t weigh down the balloon).
- But it must also be strong enough to hold hot air without tearing.
- So: light and strong
- Order: “light but strong” makes sense — lightweight yet durable.

4. "A hot air balloon can float on air as it is lifted by the [ ] air..."
- This is hot air — the principle of hot air rising.
- So: hot

✔ Final Answer:

> A hot air balloon is an aircraft. It consists of two parts, the basket and the gas bag. The basket is usually made of strong and sturdy woven rattan and it is sturdy enough to carry up to thirty adults. The gas bag or balloon is made of nylon which is light but strong enough to trap hot air. A hot air balloon can float on air as it is lifted by the hot air caused by a burner attached to it. As the burner heats the air, the hot air will move upwards and get trapped in the gas bag.

🔍 Explanation Summary:

- Strong / Sturdy: Both describe durability; used for the basket and nylon.
- Light: Nylon is lightweight, which helps the balloon rise.
- Hot: The key reason for lift — heated air is less dense.
- Sturdy: Emphasizes the basket’s ability to support weight.

This solution fits both logic and scientific principles behind hot air balloons.
