Poor Trays<br>Tim was trying to make ice. He had to do it the old fashioned way with trays. Tim's trays were old and breaking apart. He got pieces of broken plastic everywhere. Tim finally decided to invest in new trays.
Tim made ice trays to make ice but they kept breaking apart so he decided to invest in new trays.
Tim didn't make ice trays; he made ice with the ice trays. The ice trays were old which is why they were breaking apart, so he couldn't have made new old trays. I think the system read ice trays and ice as similar subjects.
