Advice columnist: Parents should not encourage their children to place great value on outdoing others.
Conclusion (should = opinion)
Parents should not encourage their kids to try to outdo others.
Evidence
Trying to outdo others fosters resentment, and it makes you less happy by leading you to pursue a goal that's hard to achieve.
Evaluate
Most correct answers on Strengthen + Principle are conditional rules, in which the trigger applies to the Evidence and the outcome sounds like our Conclusion.
Both the evidence and the conclusion here were about "trying to outdo others".
We need our answer to help us prove that Parents should not encourage this.
The evidence told us a few things about "trying to outdo others": - it fosters resentment - it makes us less happy - it gives us a goal to chase that is hard to achieve
Goal
We want an answer with a trigger that applies to any subset of those three things we know about "trying to outdo others", and a right side that sounds like "parents should not encourage this".
Since the correct answers are usually conditional logic statements, we want to be thinking that the correct answer may need to be contraposed in order to look like the argument. Similarly, there might be "right ideas, wrong order" like an Illegal Negation or Reversal of the argument.
