47. Select the word or phrase that makes the following sentence grammatically correct: Sometimes, the condition ___ with an unusual symptomâ€"vertigo.
Answer: B
Sometimes, the condition presents with an unusual symptom—vertigo.
The grammatically correct word to complete the sentence is "presents," which functions as the third person singular form of the verb, aligning with the singular subject "condition."
A) presense
"Presense" is a misspelling of "presence," which refers to the state of being present. It does not fit grammatically in the sentence as a verb, making it an incorrect choice.
B) presents
"Presents" is the correct choice as it correctly conjugates the verb "present" for the singular subject "condition." This usage indicates that the condition is showing or revealing the symptom of vertigo, thus making the sentence grammatically correct.
C) present
"Present" is the base form of the verb, which is not appropriate in this context since it does not agree with the singular noun "condition." Therefore, it does not provide the correct grammatical structure needed for the sentence.
D) prescience
"Prescience" refers to the knowledge of events before they happen and does not have any grammatical or contextual relevance to the sentence. It fails to serve as a verb that would complete the thought appropriately.
Conclusion
The choice "presents" is definitively correct as it aligns with the grammatical requirements of the sentence and accurately reflects the intended meaning. All other options are either incorrect due to spelling errors, incorrect verb forms, or lack relevance to the context of the sentence.
