8. Select the word that correctly completes the following sentence: The intern was surprised by the amount of pain he was in after his first day of work.
Answer: A
The word that correctly completes the sentence is "amount."
The intern was surprised by the amount of pain he was in after his first day of work, indicating that he experienced a significant level of discomfort.
A) amount
This option is correct because "amount" appropriately describes the extent or degree of pain experienced by the intern. It conveys a sense of quantity related to a non-countable noun, which in this case is pain.
B) frequency
"Frequency" refers to how often something occurs, which does not fit the context of the sentence. The intern's surprise relates to the level of pain rather than how often he felt it, making this option incorrect.
C) number
While "number" pertains to countable items, it is not suitable for the context of pain, which is typically unquantifiable in this manner. Therefore, this option fails to accurately complete the sentence.
D) amplitude
"Amplitude" is a term often used in physics to describe the extent of a wave or signal, and it is not appropriate for describing pain in this context. Thus, it does not fit the intended meaning of the sentence.
Conclusion
The correct choice, "amount," effectively captures the degree of pain the intern experienced, while the other options either misinterpret the context or are unsuitable for describing pain. This illustrates the importance of selecting words that align with the nature of the noun they modify.
