Establish/Maintain a Formal Argument Style Practice Test

Revise the following sentence so it maintains a formal style appropriate for an academic argument (objective tone, precise vocabulary, no contractions):

“Kids can’t focus because the hallway noise is super annoying, so the school should do something about it.”

A student begins an academic essay about requiring daily independent reading time with a formal tone:

"Consistent independent reading improves vocabulary development and reading comprehension over time. Therefore, schools should allocate at least fifteen minutes daily for independent reading."

Which revision of the next sentence best maintains the established formal style?

Original next sentence: "Plus, it’s pretty obvious that kids who read more do better in basically every class."
