The correct Answer is:
To solve the question regarding which wood has a specific gravity of less than 0.05, we can follow these steps: ### Step-by-Step Solution: 1. **Understand Specific Gravity**: Specific gravity is a measure of the density of a substance compared to the density of water. A specific gravity of less than 0.05 indicates that the wood is very light and has a low density. 2. **List the Given Options**: The options provided are: - Okroma - Olea - Lorifalia - Xyla - Dolbaeva - Briiformis - Essencynum - Hispidia 3. **Identify the Correct Options**: From the video transcript, it is stated that the correct options for wood with a specific gravity of less than 0.05 are **Essencynum** and **Hispidia**. 4. **Understand the Characteristics of the Correct Options**: - Both Essencynum and Hispidia belong to the **Fabaceae** family, which is known for having leguminous plants. - These plants are characterized by their lightweight wood, making them suitable for crafting artifacts and handicrafts. 5. **Conclude the Answer**: Therefore, the woods with specific gravity less than 0.05 occur in **Essencynum and Hispidia**. ### Final Answer: The correct options are **Essencynum and Hispidia**. ---
