A. Yes

B. No

Explanation: National parks are large areas of land, often with unique natural beauty, significant historical or scientific value, or ecological importance that are protected and maintained by a national government.

Question 2: Which of the following descriptions accurately characterize Podyjí National Park based on the provided study materials?

A. It features a unique river valley with a mosaic of rock slopes and steep walls.

B. It is known for its high mountain slopes and alpine meadows, including the highest Czech mountain Sněžka.

C. It is characteristic for its meanders, plain meadows, and sunny forest-steppes.

D. It is the largest national park in the Czech Republic, covering an area of 680.64 km2.

Question 4: According to the study materials, why are conservation efforts considered crucial for preserving biodiversity?

A. They focus exclusively on reintroducing endangered species.

B. They are essential for maintaining healthy and functional ecosystems.

C. They aim to protect and restore natural environments and wildlife.

D. They only involve establishing protected areas without other activities.

Explanation: The study materials state that 'Conservation efforts are crucial for preserving biodiversity and ensuring that ecosystems remain healthy and functional.'
