Passage: This morning I got out of bed and saw what a mess it was . The first thing I needed to do was pull the blanket off . I put the bottom sheet 's elastic corners back on all four corners of the bed . After I got that fixed , I straightened out the flat sheet , pulled it across the whole bed and tucked the bottom of it between the mattress and box springs . I pulled the flat sheet up at the top of the bed and made it smooth . Then I put my pillow back inside its case . I shook it down into the case and placed it at the top of the bed . I stepped back and glanced at my nicely made bed . Question: What part of the flat sheet did they place under the mattress? Option1: The bottom sheet Option2: The top sheet
The bottom sheet
