Which barrier to effective listening is displayed when helga listens to sven very carefully until he says something she can use against him, and then she interrupts?

This is criticizing the speaker. This makes it difficult to effectively listen when the listener already knows that there is a fact or point that is going to be used against the speaker. In addition, by interrupting, the rest of the points that might be made by Sven are lost in her rebuttal.

Water(like when there is a hurricane)some foods(not enough for everyone)
