1 is wrong.

answer to question 1: i think its C

I think it's C also -- but I'm not positive.

To find the answer to these questions, you can use the process of elimination or logic.

1. In order to determine the correct answer for the first question, it's important to consider the context. We are looking for a word that fits into the sentence and relates to the importance of communication skills in interacting with people from different backgrounds. Let's evaluate the options:

A. "Careers" - Communication skills are certainly important in various careers, but the sentence doesn't specifically mention careers.
B. "Changes" - While changes can impact communication, it is not directly related to interacting with people from different backgrounds.
C. "Technology" - Technology can facilitate communication, but it is not addressing the aspect of interacting with people from different backgrounds.
D. "Personal relationships" - This option aligns with the sentence and highlights the importance of communication skills when dealing with people from different backgrounds.

Therefore, the correct answer for the first question is D. "Personal relationships."

For the second question, let's evaluate the given options:

A. "Sender and message" - These elements are essential in a communication model.
B. "Receiver and channel" - These elements are essential in a communication model.
C. "Feedback" - Feedback is an essential element in a communication model.
D. "Caller, answerer, and sales pitch" - This option seems out of place, as it includes specific elements that are not typically part of a standard communication model.

Hence, the correct answer for the second question is D. "Caller, answerer, and sales pitch." This option does not fit with the other essential elements of a communication model.

Therefore, the answer for the second question is D.
