Teacher:In this task, you're given a context passage, followed by a question that needs to be answered. Based on the paragraph, you must write unambiguous answers to the questions and your answer must refer to a specific phrase from the paragraph. If multiple answers seem to exist, write the answer that is the most plausible.
Teacher: Now, understand the problem? Solve this instance: My old fashioned alarm clock did not go off this morning, subsequently I was late for work. I didn't have time to change the batteries so I waited until after work. Once home, I picked up the clock and used a Phillips head screwdriver to open the back of the clock. Using my finger nail I pulled on each of the two batteries from one side until they came loose. I put the dead batteries in the used battery drawer for recycling at a later date. I grabbed two fresh batteries from the adjacent drawer. I popped the batteries, making sure the positive and negatives were properly aligned and I screwed the plate back on with the screwdriver. I had to reset the time which wasn't hard, I just turned the dial on the back until it was correct. I then reset the alarm as well so that I would not be late from oversleeping the next day as well.
Question: Why did the batteries need changing?
Student:
They were no longer working.
