Jewel had carefully planned presentation aids for her speech on "Quilting." She thoroughly demonstrated how to sew together the squares by hand, which required her to concentrate her eye contact on the quilt.

What guideline for using presentation aids did Jewel violate?.

she focused on the presentation aid instead of the audience.

Explanation:

Based on the scenario being described within the question it can be said that the guideline that Jewel violated is that she focused on the presentation aid instead of the audience. When giving a presentation the speaker needs to always focus on the audience in order to visualize their reactions and make the audience feel as though they are important and relevant to the speech itself. By focusing on the quilt and not the audience, Jewel is violating this guideline.

the president has the power to appoint federal judges, ambassadors, and other "principal officers” of the united states, subject to senate confirmation of such appointments.

the earth’s crust is broken into separate pieces called tectonic plates (fig. 7.14). recall that the crust is the solid, rocky, outer shell of the planet. it is composed of two distinctly different types of material: the less-dense continental crust and the more-dense oceanic crust. both types of crust rest atop solid, upper mantle material. the upper mantle, in turn, floats on a denser layer of lower mantle that is much like thick molten tar.

each tectonic plate is free-floating and can move independently. earthquakes and volcanoes are the direct result of the movement of tectonic plates at fault lines. the term fault is used to describe the boundary between tectonic plates. most of the earthquakes and volcanoes around the pacific ocean basin—a pattern known as the “ring of fire”—are due to the movement of tectonic plates in this region. other observable results of short-term plate movement include the gradual widening of the great rift lakes in eastern africa and the rising of the himalayan mountain range. the motion of plates can be described in four general patterns:

collision: when two continental plates are shoved together

subduction: when one plate plunges beneath another (fig. 7.15)

spreading: when two plates are pushed apart (fig. 7.15)

transform faulting: when two plates slide past each other (fig. 7.15)
