12. Select the word or phrase that makes the following sentence grammatically correct: Sometimes, the condition ............. with an unusual symptomÄ€â€vertigo.
Answer: B
Sometimes, the condition presents with an unusual symptom: vertigo.
The appropriate word to complete the sentence is "presents," which correctly indicates that the condition shows or manifests a symptom.
A) presense
"Presense" is not a valid English word and therefore cannot be used to complete the sentence. The intended word likely refers to the act of showing or manifesting, which this option does not convey.
B) presents
"Presents" is the correct choice as it is the third-person singular form of the verb "present," meaning to show or exhibit. This fits grammatically in the sentence, conveying that the condition displays an unusual symptom.
C) present
"Present" is the base form of the verb and does not agree with the singular subject "the condition." It would be incorrect to use this form in this context, as it does not match the subject's tense and number.
D) prescience
"Prescience" refers to the ability to know or predict events before they happen and is unrelated to the context of the sentence. It does not fit grammatically or semantically as a substitute for the verb needed in this sentence.
Conclusion
The word "presents" is definitively the correct choice as it properly aligns with the subject and conveys the intended meaning of the sentence. All other options fail to meet grammatical standards or do not relate to the context of exhibiting symptoms, making them incorrect choices.
