The correct answer to the given question is option 'C,' i.e., a very low height from sea level. Bamboos are mostly found in lowland areas, and they grow best in warm and humid conditions. Most of the bamboo species grow well at an elevation of 500 meters or less from sea level, and they prefer well-drained soils with a high content of organic matter.

Tropical and Subtropical Regions

Bamboos are commonly grown in tropical and subtropical regions, including Asia, Africa, South America, and Australia. In these areas, the climate is suitable for bamboo growth, and there is an ample supply of water.

Uses of Bamboo

Bamboos have numerous uses, including:

1. Construction material: Bamboo is used extensively for construction purposes, including building houses, bridges, and other structures.

2. Furniture: Bamboo is also used to make furniture like chairs, tables, and beds.

3. Paper production: Bamboo is a good source of pulp for paper production.

4. Food: Certain species of bamboo are used as food, and they are a rich source of nutrients.

5. Ornamental purposes: Bamboos are used for ornamental purposes, and they add beauty to gardens and landscapes.

Conclusion

In conclusion, bamboos are grown mostly at a very low height from sea level. They are commonly found in tropical and subtropical regions, and they have numerous uses, including construction material, furniture, paper production, food, and ornamental purposes.

Opening of the Suez Canal
The Suez Canal was opened in 1869, making it the correct answer to the question. Here is a detailed explanation of the opening of the Suez Canal:

Construction of the Suez Canal
- The construction of the Suez Canal began in 1859 under the leadership of the French diplomat Ferdinand de Lesseps.
- The canal was built to connect the Mediterranean Sea to the Red Sea, providing a more direct route between Europe and Asia.

Impact of the Suez Canal
- The opening of the Suez Canal in 1869 had a significant impact on global trade and transportation.
- It reduced the travel time for ships traveling between Europe and Asia by eliminating the need to sail around the southern tip of Africa.
- The canal also played a crucial role in the colonization of Africa and Asia by European powers, as it facilitated easier access to these regions.

Significance of the Suez Canal
- The Suez Canal quickly became one of the world's most important waterways, handling a large portion of global trade.
- It remains a vital artery for international shipping, connecting the Mediterranean Sea to the Indian Ocean and beyond.
- The canal has also been a site of political tension and conflict, with control over its operations being a source of contention between various countries over the years.
In conclusion, the opening of the Suez Canal in 1869 was a pivotal moment in the history of global trade and transportation, shaping the movement of goods and people between Europe and Asia.

Range of the Intensity Scale in Measuring Earthquakes

The intensity scale used in measuring earthquakes is known as the Modified Mercalli Intensity (MMI) scale. It is a subjective measure that assesses the effects of an earthquake on people, buildings, and the environment. The scale ranges from I (not felt) to XII (total destruction), with each level representing increasing levels of intensity and damage.

Understanding the MMI Scale
The MMI scale is different from the magnitude scale, such as the Richter scale or Moment Magnitude scale, which measure the energy released by an earthquake. Instead, the MMI scale focuses on the impact of the earthquake on human experiences and infrastructure.

The intensity of an earthquake is determined by factors such as the magnitude, distance from the epicenter, local geology, and building design. Intensity levels are based on observations and reports from people who experienced the earthquake.

Range of the MMI Scale
The range of the MMI scale is from I to XII. Here is a breakdown of the levels:

1. I - Not felt: The earthquake is not felt except by a very few under especially favorable conditions.
2. II - Weak: Felt only by a few individuals at rest, especially on upper floors of buildings.
3. III - Weak: Felt noticeably indoors, especially on upper floors of buildings, but many people do not recognize it as an earthquake.
4. IV - Light: Felt indoors by many, outdoors by few during the day. At night, some awakened. Dishes, windows, doors disturbed; walls make cracking sound.
5. V - Moderate: Felt by nearly everyone; many awakened. Some dishes, windows, and glassware broken; unstable objects overturned. Pendulum clocks may stop.
6. VI - Strong: Felt by all, many frightened, run outdoors. Some heavy furniture moved; a few instances of fallen plaster or damaged chimneys. Damage slight.
7. VII - Very strong: Damage negligible in buildings of good design and construction; slight to moderate in well-built ordinary structures; considerable damage in poorly built or badly designed structures.
8. VIII - Severe: Buildings slightly damaged. Ordinary buildings shaken considerably, with partial collapse. Damage considerable in poorly built or badly designed structures. Some chimneys broken.
9. IX - Violent: Damage considerable in specially designed structures; well-designed frame structures thrown out of plumb. Damage great in substantial buildings, with partial collapse. Buildings shifted off foundations.
10. X - Extreme: Some well-built wooden structures destroyed; most masonry and frame structures destroyed with foundations. Rails bent.
11. XI - Extreme: Few, if any, masonry structures remain standing. Bridges destroyed. Rails bent greatly.
12. XII - Total destruction: Damage total. Lines of sight and level distorted. Objects thrown into the air.

Conclusion
In conclusion, the range of the intensity scale used in measuring earthquakes is from I to XII. Each level represents increasing levels of intensity and damage, from not felt to total destruction. The Modified Mercalli Intensity scale provides valuable information in understanding the impact of earthquakes on people and infrastructure.
