Final answer:
The predicate in the sentence is 'are enclosed spaces'. Option (A) is correct.
Step-by-step explanation:
The predicate in the given sentence is 'are enclosed spaces'. The predicate is the part of the sentence that provides information about the subject, 'Vivariums'. In this case, it describes the characteristics of the vivariums, stating that they are enclosed spaces.
A simple predicate is the basic word or words that explain what specific action the subject of the sentence is doing. So, in a sentence like 'The boy walks to school,' the simple predicate would be 'walks. '
A predicative expression (or just predicative) is part of a clause predicate, and is an expression that typically follows a copula or linking verb, e.g. be, seem, appear, or that appears as a second complement of a certain type of verb, e.g. call, make, name, etc.
The predicate in both the sentences is 'were covered with mud. ' A Simple Sentence may contain a Compound Predicate is a predicate with two or more verbs joined by the word and or another conjunction.
There are times when a sentence has two subjects and two predicates, but they're not compound subjects or compound predicates. These sentences are called compound sentences. They are formed when a coordinating conjunction or semicolon joins two independent clauses to create a longer sentence.
