Question

select the words that make up the complete compound subject. fernando and his lab partner built a miniature suspension bridge for their science fair project. submit

Explanation:

A compound subject is made up of two or more subjects joined by a conjunction (here "and") that share the same predicate. In the sentence "Fernando and his lab partner built a miniature suspension bridge for their science fair project", the subjects are "Fernando" and "his lab partner", joined by "and", so together they form the complete compound subject.

Answer:

Fernando, his lab partner (or written as "Fernando and his lab partner" since the question asks for the words that make up the complete compound subject, and the compound subject is "Fernando and his lab partner")
