Question

Developing a shared understanding through communication is complex because __________________.

a. everyone interprets the world differently
b. no one understands enough words to communicate effectively
c. learning to communicate well is too difficult
d. all of the above

Answer 1

B isn't necessarily true, there are many ways to express things that are beyond one's belief which isn't a strong limitation on understanding
C is also not true, you are being taught how to express your ideas and how to make one in most situations
D is automatically not true because of B and C being false

This leaves A as the right answer because whatever seems right or logical to you might not necessarily be true or thought of in the same way to another person
