5. Choose the word or phrase that best indicates the meaning of the word in quotes. The 'insidious' disease was well established before becoming apparent.
Answer: C
The 'insidious' disease was well established before becoming apparent.
The term 'insidious' in this context refers to a disease that develops gradually and often without noticeable symptoms until it is well advanced. Therefore, the best indication of its meaning is "Gradual."
A) Sudden
This option is incorrect because 'sudden' implies a quick onset or immediate occurrence, which contradicts the nature of an insidious disease that is slow to manifest.
B) Suffer
While this option relates to the experience of a disease, it does not accurately capture the meaning of 'insidious.' It focuses on the experience of pain rather than the gradual development of the disease itself.
C) Gradual
This option is correct as it aligns perfectly with the definition of 'insidious,' indicating a slow and stealthy progression of the disease that may not be immediately apparent.
D) Graduate
This choice is incorrect, as 'graduate' pertains to completing a course of study or moving up in stages, which has no relevance to the gradual onset or nature of a disease.
Conclusion
The correct answer, "Gradual," clearly reflects the nature of an insidious disease, which is characterized by its slow and often unnoticed progression. All other options fail to accurately convey this concept, emphasizing the importance of understanding the subtlety of medical terminology.
