How should the word "invisible" be used in describing signs of stress?

• A. It is used incorrectly because signs of stress cannot be 'invisible' if you are looking for them.
• B. It describes signs of stress that are visible to everyone.
• C. It should be used to describe signs of stress that are not visible.
• D. It is used to emphasize that signs of stress are always visible.

Answer: (A)

The main idea is that invisible describes signs of stress that are not seen on the outside. Some indicators of stress are internal or subtle and may not be obvious to others just by looking. When you say there are invisible signs, you’re pointing to those internal experiences—like worry, fatigue, headaches, stomach upset, or racing thoughts—that a person may feel or sense rather than display openly. Describing signs as invisible helps emphasize that outward appearances can be misleading and that understanding stress often requires listening to how a person feels or looking for patterns over time, not just what you can observe at a single moment. So, the best use is to refer to signs that are not visible, rather than signs that must be visible or that are always evident.
