Final answer:
The sentence should be retained as it is to maintain the consistent tone and style of the passage that focuses on generational language trends and the use of 'emojis' as a precise term over 'symbols' or 'emoticons'.
Step-by-step explanation:
To address the student's question, we must consider the tone and style that consistently appears throughout the passage. The reference to emojis in the sentence clearly aligns with the overall discussion, but the key to consistency here lies in the specific word choice. Given the context of emojis being part of a generational language, the term "emojis" reflects current linguistic trends and is more precise than the word "symbols". Changing "emojis" to "emoticons" may not serve well as emoticons often refer to a more traditional set of text-based facial expressions (e.g., :-), :-( ) and could slightly alter the intended distinction from the passage. Therefore, option a) Retain the sentence as it is remains the best choice to ensure consistency in tone and relevance to the subject matter of generational communication styles and the evolution of language.
