All of the following are factors that can interfere with effective communication except  visual and audible noise   the power relationship between speakers Correct!  decision-making   degree of shared knowledge between speakers

The factors that can interfere with effective communication are:

1. Visual and Audible Noise: This can distract the sender or receiver, making it difficult for the message to be accurately conveyed or understood.

2. The Power Relationship Between Speakers: If there is a significant power imbalance between the sender and receiver, it can affect how the message is interpreted. The receiver may feel pressured to agree with the sender, or they may feel uncomfortable expressing their own thoughts and opinions.

3. Degree of Shared Knowledge Between Speakers: If the sender and receiver do not have a common understanding or shared knowledge about the topic of communication, it can lead to misunderstandings or misinterpretations.

However, decision-making is not a factor that interferes with effective communication. Decision-making is a process that follows communication. Once a message is received and understood, the receiver then makes a decision based on the information received. Therefore, the correct answer is "decision-making".
