15. Select the meaning of the underlined word in this sentence. He complained of the *adverse* side effect of his new medication.
Answer: C
C: Undesirable
The term *adverse* in this context refers to something that is harmful or unfavorable. Therefore, it signifies a side effect that is not beneficial, aligning perfectly with the meaning of "undesirable."
A) Constant
The option "Constant" implies something that occurs regularly or without interruption. While side effects can be constant, this term does not capture the negative connotation of *adverse*, making it an incorrect interpretation of the word in this context.
B) Noticeable
"Noticeable" suggests that something can be readily seen or perceived. Although *adverse* side effects may be noticeable, the term does not convey the negative implications inherent in *adverse*, thus rendering it an unsuitable choice.
C) Undesirable
This option accurately reflects the meaning of *adverse*, which denotes something harmful or unfavorable. Undesirable side effects are precisely what one would expect from the term *adverse*, making this the correct answer.
D) Frequent
"Frequent" denotes something that occurs often or repeatedly. While an adverse side effect could potentially be frequent, this word fails to encapsulate the negative aspect of *adverse*, making it an incorrect interpretation in this context.
Conclusion
The correct interpretation of *adverse* as "undesirable" is essential for understanding the negative implications of side effects associated with medication. All other options either misinterpret the meaning or lack the necessary negative connotation, reinforcing that "undesirable" is the only suitable choice in this context.
