Review the student's dramatic text messages to her friend about an upcoming exam. Select ALL the options that apply the correct time prepositions.
The correct answers are I will study until midnight! and I will study from 8 PM to midnight!
Use until to show when an action stops (like studying up to the point of midnight).
Use from... to... to show both the start and end times.
"For" is only used with lengths of time (like "for three hours"), and "since" is used for a starting point in the past, not the future!
