Answer:
We know if a material is worth seeing if that material does not assist in any activity or knowledge, or if it can be used for our entertainment and enjoyment.
Step-by-step explanation:
Although it is not possible to know the types of viewing materials that you saw in your previous lessons, we can say that viewing materials are objects that present us with information and allow us to see things that can be very useful for us and our activities. Among these viewing materials, we can mention magazines, computers, cell phones, televisions, power point presentations, books, among others.
Within these viewing materials, we can select those that will help us in our activities, provide valuable knowledge, or allow us to entertain. Those who do not fit into this category may be irrelevant to us and are not worth seeing.
