Answer:
Four adults and a child were trapped, but they were safely rescued.
Explanation:
In a sentence with correct subject-verb agreement, the subject and the verb match in person (First, second or third person), plural (singular or plural), and uses the verb tenses properly. The sentence number 1 is the correct sentence because it has all those characteristics: "Four adults and a child" is a noun in third-person plural, and the form of the verb "to be" that matches with noun in third person plural is "were", while "was" matches with third-person-singular pronouns such as "she", "he" and "it" and the first person singular pronoun: "I".
