Step-by-step explanation:
Bangladesh is called a country prone to flooding due to its low-lying geographical location and the presence of the Bengal Delta, where heavy monsoon rains can cause extensive damage. It is also known as a developing nation with a high population density, seeking to balance economic growth with environmental challenges and social issues such as poverty and the need for improved public services and infrastructure, especially in rural areas. Furthermore, Bangladesh is called a country of cultural richness with a variety of ethnic groups and the prominence of the Bengali language, which reflects the nation's historical and linguistic heritage.
