Which of the following scenarios is (are) incidence(s) of human mistake? Multiple answers Group of answer choices Blanche, when measuring out their flour, accidently drops it on the floor. They don’t have any extra so they decide to pick it up and use the now contaminated flour in the experiment. Feng acquires their ingredients to make their cake but forgets to add the granulated sugar. They don’t notice until it is too late to fix. When taking readings of the cake volume, CJ takes a measurement and then writes down the time. There are a few seconds between CJ's time of reading and their ability to look at the clock. Lisa looks into the oven as their cake is baking, in order to record the volume of their cake, Lisa will need to estimate the reading based off the graduations on the beaker.
