These questions deal with situations that you may have to face (or others have faced in the past). Submit your answer so that you completely answer the question and solve the problem. Some questions do not have a definitive answer; you must explain your reasoning as best you can.
The starship USS Compaq has entered an area of space where there are no visible stellar phenomena. Sensors are picking up high levels of gamma radiation and radio waves that do not seem to come from any visible source. What is the phenomenon and what should be your recommendation?
The USS Gateway has received reports that the blue dwarf star Gamma Epsilon has increased in size over the course of two years. The captain suspects a supernova and has ordered the evacuation of the only inhabited planet, Gamma Epsilon IX. Is the captain correct? If he is not, what is the correct phenomenon and what actions should be taken?
The crew of the USS Hewlett-Packard has encountered a microscopic object that has been causing nothing but problems for the Klingon ship IKC EpsonCanon. What began as one object has turned into forty-seven similar objects in only one hour. The objects are draining power from the warp core at a rate that will quickly disable the Klingon vessel. The objects are not known lifeforms; they look very different from any known microscopic entities. Are they alive? If so, why? And what should be done with them?
