Thank you for using the timer!
We noticed you are actually not timing your practice. Click the START button first next time you use the timer.
There are many benefits to timing your practice, including:
A.where, for a premium price, fans are allowed to view the action from the sidelines closely.
B.on the sidelines where, for a premium price, they are allowing fans to view the action closely.
C.where, for a premium price, fans will be allowed to closely view the action from the sidelines.
D.close to the sidelines where fans can view the action for a premium price.
E.where, for a premium price, fans are allowed to view the action closely from the sidelines.
C or E
I think they differ in the place of the modifier/adverb 'closely'
closely is modifying view (verb) not the action (noun)
C is my choice.
