## Step1<br />For question 13, we need to identify the type of influence that has the most significant impact on a speaker's impact. The options provided are auditory, acoustic, visual, and sensory. The question states that 55 percent of a speaker's impact is based on this type of influence. <br /><br />## Step2<br />Among the options, visual influence is the most significant. This is because visual influence refers to the use of visual aids such as slides, charts, or videos to enhance the speaker's message. This is more impactful than auditory (sound), acoustic (related to sound), or sensory (related to the senses) influence.<br /><br />## Step3<br />For question 14, we need to identify the correct term that describes the action of refuting or disproving an opposing argument. The options provided are reject, negate, isolate, and counteract.<br /><br />## Step4<br />The term 'counteract' is the most appropriate in this context. This is because when you counteract an argument, you are actively working to disprove or refute it, rather than simply rejecting or negating it. Isolating an argument does not necessarily mean disproving it.
