Hepatitis A in most cases is acquired through contaminated food or drinks or direct contact with people infected.
Since Ray went on a missionary trip to a developing country and contracted Hepatitis, its likely its Hepatitis A because he was involved in their cultural celebration involving eating their local food or drinks probably prepared in a poor sanitation environment or direct contact with affected persons as this is the way Hepatitis A can be contracted.
The question is incomplete. So the complete question and answer are given below:
You are talking with a friend in a closed room that has no windows, no objects, and no furniture. The only thing in the room is an overhead incandescent light that is turned on. You are looking at your friend and begin thinking about whether you are seeing your friend as a result of reflection. Does reflection play a role in seeing your friend? Group of answer choices:
Yes, the visible light from the overhead light bulb is diffusely reflected from my friend and enters my eye.
Reflection is the change in direction of the wavefront at the interface between two different media such that the wavefront returns to the medium of origin. Common examples are the reflection of light, sound, and water waves. According to the law of reflection, in specular reflection (such as from a mirror), the angle at which the wave hits the surface is equal to the angle at which it is reflected.
In acoustics, reflections cause echoes and are used in sonar. In geology, it is important for the study of seismic waves. Reflections are observed in surface waves in water bodies. Reflections are seen in many electromagnetic waves besides visible light. Reflections from VHF and higher frequencies are important for radio transmission and radar.
