Correct answer: The Grand Canyon was created by the Colorado River over millions of years.
The passage primarily explains how the Grand Canyon was formed, stating it "was formed over millions of years as the Colorado River cut through layers of rock." This sentence directly addresses the origin and process of its creation, making it the central theme. Although it mentions tourism, the main idea revolves around its geological formation.

- It will grow faster.
- It will grow only with water.
Correct answer: Its growth might be stunted.
The passage explicitly states, "Without these essential elements, their growth may be stunted, and they may not produce flowers or fruit." Therefore, if a plant lacks necessary elements like sunlight, water, and nutrients, its growth will be negatively impacted, specifically becoming stunted. This directly answers what happens when essential elements are missing.
Question 3: Electric cars are becoming increasingly popular due to their efficiency and environmental benefits. Unlike traditional vehicles, they produce no emissions, which helps reduce air pollution. <br> Why are electric cars considered better for the environment than traditional vehicles?

This adaptation to harsh conditions, such as extreme heat and limited water, is what makes them unique in such an environment. Their ability to thrive despite these challenges is a key characteristic.
