Final answer:
Curiosity and change acceptance are the two critical tendencies for acquiring a global mindset, promoting cultural understanding and adaptability to overcome ethnocentrism.
Step-by-step explanation:
The two tendencies critical to acquiring a global mindset are curiosity and change acceptance. A person with a global mindset is typically open to and interested in learning about different cultures, perspectives, and ways of life. Curiosity drives an individual to seek out new information and experiences, leading to a greater understanding of the global community. On the other hand, change acceptance is the ability to adapt and be flexible in a world that is constantly evolving, where cultural dynamics, global issues, and social norms shift regularly. Both qualities help individuals navigate and engage effectively in a world defined by cultural diversity and interconnectedness, and are essential for overcoming ethnocentrism, the belief that one's own culture is superior to others.
