Question 5

Labile means rapidly changing.

Labile refers to something that is subject to frequent and rapid changes, often indicating instability or variability in a given context.

A) Extremely changing

While "extremely changing" suggests a significant degree of change, it lacks the precision of the term "rapidly changing." The term "labile" specifically implies quick and frequent shifts rather than just a high level of change.

B) Extremely changeable

"Extremely changeable" indicates a potential for change, but does not emphasize the speed of change that is inherent in the definition of "labile." Therefore, it does not capture the essence of what "labile" conveys.

C) Rapidly changing

This option accurately reflects the definition of "labile." It describes a state of being that is characterized by quick and frequent fluctuations, which is the core meaning of the term.

D) With a high fever

This choice is incorrect as it relates to a medical condition rather than the concept of change. "Labile" does not imply anything about fever or temperature, making this option irrelevant.

Conclusion

The definition of "labile" is best captured by the phrase "rapidly changing," as it highlights the characteristic of quick fluctuations that the term embodies. The other options either misinterpret the term or fail to convey its specific meaning, reinforcing that C is the most accurate choice.
