which sentence or sentences have correct parallel structure? while the queen bee in a honeybee colony lays the eggs, the worker bees perform a variety of functions, including searching for food, building the hive, and circulating air within the hive. while the queen bee in a honeybee colony lays the eggs, the worker bees perform a variety of functions, including searching for food, building the hive, and they increase air circulation within the hive.
Answer
Brief Explanations:
Parallel structure requires elements in a list to have the same grammatical form. In the first sentence, "searching for food", "building the hive", and "circulating air within the hive" are all -ing verb phrases, maintaining parallelism. In the second sentence, "searching for food" and "building the hive" are -ing verb phrases, but "they increase air circulation within the hive" is a clause, breaking the parallel structure.
Answer:
The first sentence: While the queen bee in a honeybee colony lays the eggs, the worker bees perform a variety of functions, including searching for food, building the hive, and circulating air within the hive.
