Statement1-
Given-Standard shipping was the only method of shipping used for items purchased on the first day.
=> All items sold on the first day were shipped using standard shipping, which could include both clearance and non-clearance items. Also, it does not specify whether Cory's item was purchased on the first day, nor does it provide any information about the nature of Cory's item.
So, Statement1 is insufficient.
Statement2-
Given- The item Cory purchased was a clearance item.
=> Cory's item was shipped with standard shipping (since all clearance items are shipped with standard shipping). However, this does not specify which day Cory made the purchase, as clearance items could have been sold on either day.
So, statement2 is also insufficient
Taking both statements together-
From Statement1- all items purchased on the first day were shipped with standard shipping.
From Statement2- Cory's item was a clearance item and was shipped with standard shipping.
So, even together the statements are insufficient.
