Answer: "Fashion forecasting involves predicting future trends by observing changes in the current situation and learning from the past trends."
Step-by-step explanation:
The sentence in the passage that uses parallel structure is:
"Fashion forecasting involves predicting future trends by observing changes in the current situation and learning from the past trends."
In this sentence, the parallel structure is evident in the repetition of the gerund phrase "observing changes" and "learning from." Both phrases are in the present participle form and are connected by the coordinating conjunction "and."
Parallel structure is a writing technique that involves using the same grammatical structure or pattern for similar elements in a sentence or paragraph. It helps to create clarity, balance, and rhythm in writing. In this case, the parallel structure emphasizes the two actions involved in fashion forecasting: observing changes in the current situation and learning from past trends.
Hope this helps
