Answer:
Sentence that has both compound subject and a compound predicate is: 1. Beth and Linda have been shopping and will go swimming
Step-by-step explanation:
A sentence will have compound predicate if the subject in the sentence would perform more than one action. The verbs on the sentence would be joined by a conjunction 'and', 'but', 'or'.
Compound subject means a sentence has two or more subjects. They are joined with a conjunction.
In the first sentence, there are two subjects, Beth and Linda, they are performing two actions: shopping and swimming. Verbs are joined with conjunction 'and'. Thus, this is the correct option.
