Read the following passage and identify the main idea: The water cycle is the continuous movement of water on, above, and below the Earth's surface. It is driven by the sun's energy and involves processes such as evaporation, condensation, and precipitation. Water evaporates from bodies of water, such as lakes and oceans, and rises into the atmosphere. It then condenses into clouds and falls back to the Earth as precipitation, which can be in the form of rain, snow, or hail. The water cycle is essential for the distribution of water and plays a crucial role in the Earth's climate system. What is the main idea of this passage?

• The main idea is the distribution of water in lakes and oceans.

• The main idea is the role of the sun's energy in the water cycle.

• The main idea is the water cycle and its importance.

• The main idea is the process of evaporation and condensation.

Read the following passage and identify the main idea: The human body is made up of many different systems that work together to keep us alive and healthy. One of these systems is the respiratory system, which is responsible for the exchange of oxygen and carbon dioxide in the body. When we breathe in, oxygen enters our lungs and is transported to our cells through the bloodstream. At the same time, carbon dioxide, a waste product, is removed from the cells and exhaled. The respiratory system is essential for the survival of all living organisms. What is the main idea of this passage?

• The human body is made up of only one system.

• The respiratory system only transports carbon dioxide in the body.

• The respiratory system is essential for the survival of all living organisms.

• The respiratory system is not important for the survival of living organisms.
