Final answer:
To maintain an academic tone, choose words with positive connotations and ensure they are appropriate for the audience. Use a dictionary for correct spellings, or opt for known words to reduce errors in academic texts.
Step-by-step explanation:
When writing an academic text, it is essential to use words with a positive connotation that are appropriate for the targeted audience. Considering the sentence provided, where the underlined words need to provide necessary information within an academic context, substituting them with words that have a positive connotation and are applicable is crucial.
For example, in the sentence, "The math curriculum that the district adopted 10 years ago no longer meets the needs of the students," replacing the word current (which has been removed) with underlined words like "existing" or "present" can convey the necessary information while maintaining an academic tone.
It is also important to ensure correct spelling when choosing replacement words. If unsure about the spelling, using a dictionary or selecting an alternative word with a known correct spelling is advisable, as it helps in reducing mistakes and improving the quality of the writing.
