Final answer:
EPICAC could refer to Vonnegut's fictional computer that prints answers, or a modern AI that displays answers on a screen. Modern systems process input, search for information, and apply logic to relay answers in user-friendly formats like text or speech.
Step-by-step explanation:
The question "How does EPICAC relay answers?" seems to be referring to a fictional computer called EPICAC from a short story by Kurt Vonnegut, or it could be inquiring about a computer system that homework systems or artificial intelligences use to provide answers.
In the context of Vonnegut's story, EPICAC is a supercomputer that becomes sentient and communicates by printing out answers on paper. In a more realistic scenario, a computer system such as an AI on a homework help platform may relay answers through a user interface where the system processes the input question, computes the answer, and then displays it on the screen for the user to read. The computation typically involves parsing the question, searching a database or the internet for relevant information, and then applying algorithms or programmed logic to come up with the correct answer. The answer could be displayed as text, spoken through text-to-speech technology, or presented in some other user-friendly format.
