Final answer:
The informal sentence about field trips can be rephrased in a formal essay style as: 'There are numerous factors that deter school administrators and educators from organizing field trips.' This maintains the original meaning while using more academic language.
Step-by-step explanation:
For a more formal essay style, the sentence 'School administrators and teachers shy away from field trips for several reasons.' could be rephrased as: 'There are numerous factors that deter school administrators and educators from organizing field trips.' This revision maintains the original meaning while employing a more academic tone. In formal writing, precise language and a neutral tone are optimal. It is essential to avoid colloquial expressions and maintain a degree of formality to align with academic standards.
Moreover, the context provided indicates that neither students nor teachers have suggested a field trip, and there are broader implications concerning the quality of the educational environment and the allocation of time for recreational activities. The sentence should reflect understanding of these educational challenges as well.
