Answer:
3. mean neither the same nor opposite.
Explanation:
To be "present" describes the action of existing or occurring in a particular moment. It also refers to a time period that is occurring at the moment of speaking (such as, "present tense"). On the other hand, "reserve" refers to preserving something for future use, or to having a quantity of something that is not used yet, but is saved for the future. Therefore, these two words do not mean either the same or the opposite.
