Final answer:
Without the context of paragraph 2, it's impossible to provide a definitive answer on which section best supports Part A. However, phrases like 'accidentally invented' or 'icy concoction' could be relevant if the context is about the origin of an icy treat.
Step-by-step explanation:
The question from the student seems related to understanding a text passage, likely from an English or reading comprehension exercise. The student appears to be requested to identify which part of paragraph 2 from a text selection best supports a previous answer to another question (Part A). Without the context of paragraph 2, it's impossible to provide a definite answer. However, if we were to speculate purely based on the provided options, and if Part A is about the origin of a certain icy treat, then the phrase 'accidentally invented' or 'icy concoction' might be relevant. Yet, without the proper context, this is merely a speculation and shouldn't be taken as a definitive answer.
