Which one of the following most accurately identifies two flaws in the argument?

1. It casts daily exercise as required for high energy when the evidence makes it at most one route, and it hardens a most-claim into one person's certainty.
2. It mistakes mere correlation for established causal proof, and it frames the case as a false dilemma between two exclusive, exhaustive, and rigid options.
3. It distributes a property of the whole group onto a single member, and it rests its key generalization on a skewed, unrepresentative, small sample.
4. It lets one central term quietly drift in meaning throughout, and it attacks Julian's character to dismiss the very view he is said to hold here.
5. It assumes Julian's tiredness must trace to a single cause, and it ignores that a person's energy levels naturally rise and fall over time.
