Answer:
D. Jim and Alex make light conversation while traveling along the Alaskan highway.
Explanation:
Subject-verb agreement means the subject in a sentence must be of the same number as its verb. In other words, this means that if the subject is singular, the verb will be in the singular form. And a plural subject will have a plural verb.
Among the given sentences, sentence D uses the correct subject-verb agreement. The subjects "<em>Jim and Alex</em>" are plural, thereby making the verb in its plural form "make".
Sentence A uses the plural helping verb "were" for the singular subject Galilea.
Sentence B uses the singular helping verb "is" for the word "dangers" which is plural.
Sentence C also uses a singular verb for a plural subject.
Thus, the correct answer is option D.
