Shanda has created a presentation to convince the executives at Doggy Daycare, a regional chain of full-service dog boutiques, to include behavioral training in employee interactions with canine clients. It hits every mark but one: it is difficult to visually distinguish key points from the rest of the slides. What should she do to improve her presentation for ease of processing?Multiple ChoiceHave only sixty lines of text for every slide.Use at least 28-point fonts for titles and 18-point fonts for body text.Don't keep a margin of white space as a border on every slide.Use dark purple for the background and black for the text.Put key ideas in the middle of paragraphs in plain text.
