Passage: One day , a friend and I decided to bake a cake . We first looked up ingredients online to make the type of cake we wanted . Then we went to the supermarket and bought all of them . After bringing all of our ingredients home , we followed the recipe instructions closely to ensure we were not doing anything wrong . We put our ingredients together to make sure they were at the right temperature , preheated the oven , and pulled out the proper utensils . We then prepared the batter using eggs and some other materials we purchased and then poured them into a pan . After baking the cake in the oven for the time the recipe told us too , we then double checked to make sure it was done by pushing a knife into the center . We saw some crumbs sticking to the knife when we pulled it out so we knew it was ready to eat ! Question: What did they follow when getting ready to bake? Option1: recipe instructions Option2: Historical timeline.
