For the first question, the reason that fails to support the claim that high school classes should begin later than elementary or middle school classes in a meaningful way is:
Many teenagers have reported a tendency to skip breakfast, which some nutritionists consider the most important meal of the day, altogether.
This reason does not directly relate to the timing of classes or the attention span of teenagers compared to younger children, making it less relevant to the argument.
For the second question, the argument that bases decisions on the false belief that random occurrences are somehow predictive of future outcomes is referred to as:
gambler’s fallacy.
This fallacy occurs when individuals believe that past random events affect the probabilities of future random events, such as thinking that a coin flip is more likely to land on heads after several tails in a row.
