Select the sentence that does NOT have an agreement error.

Patient has had no loss of consciousness, has no headache, and there is no pain in neck.
Patient has had no loss of consciousness, has no headache, and has no pain in neck.
Patient has had no loss of consciousness, he has no headache, and there is no pain in neck.

And your answer is?

To determine the sentence that does NOT have an agreement error, we need to check for subject-verb agreement. The subject and verb in a sentence should agree in number, meaning that if the subject is singular, the verb should be singular, and if the subject is plural, the verb should be plural.

Let's analyze each sentence:

1. "Patient has had no loss of consciousness, has no headache, and there is no pain in neck."
In this sentence, the verbs "has" and "is" agree with the singular subject "patient." This sentence does not have an agreement error between the subject and the verbs.

2. "Patient has had no loss of consciousness, has no headache, and has no pain in neck."
Similar to the previous sentence, all the verbs "has" agree with the singular subject "patient." This sentence also does not have an agreement error.

3. "Patient has had no loss of consciousness, he has no headache, and there is no pain in neck."
In this sentence, there is an agreement error between the pronoun "he" and the singular subject "patient." To maintain subject-verb agreement, the pronoun "he" should be replaced with "patient." Thus, this sentence has an agreement error.

Therefore, the sentence that does NOT have an agreement error is: "Patient has had no loss of consciousness, has no headache, and there is no pain in neck." (Sentence 1)
