Answer:
The fragment that could be corrected by adding a complete predicate would be the last one: Lions and other members of the cat family.
Step-by-step explanation:
A predicate consists of a verb or a verb phrase that offers information about a subject. In other words, a predicate is everything in a structure that is not the subject. The subject is what the sentence is about, its topic.
Options 1, 2, and 3 could already be considered predicates. However, the last option does not present a verb or verb phrase. It would function as a subject of a sentence, as long as we added a predicate to it. Here are a few examples:
- Lions and other members of the cat family are known for being amazing predators.
- Lions and other members of the cat family usually let their females do the hunting.
- Lions and other members of the cat family can run faster than 80km/h.
