Hi Loveydog,
The best way to solve a Parallel Reasoning question is to break down the stimulus into its constituent parts and find the answer choice that has the same exact parts. Here we're given a conditional conclusion:
Journalist

Should Have Reasonable Knowledge Statistics
based on two premises. First, another conditional statement:
Reasonable Knowledge Statistics 
Can Make Errors
and then an actual situation that complies with the conditional premise:
Reasonable Knowledge StatisticsJournalist 
Error
Journalist
So what we need to look for is an answer choice that gives a conditional premise, then another premise illustrating an example of the conditional relationship at work, then finally concludes the contrapositive of the example premise (albeit not necessarily in that order).
(B) gives us:
Conclusion: School

Should Have Recess Time
Checks out, same exact scope as the conclusion in the stimulus. It continues with a premise:
Recess Time 
Children Can Incur Health Risks
So far, so good, looks exactly the same as the stimulus. Lastly, we have the example premise:
Recess TimeA School 
Students Less Fit
Looks like a 1:1 match with the stimulus. Contrast this to (E):
Conclusion: Toy Manufacturer

Should Record on Toy
Ok so far, then the premise:
Record on Toy 
Easily Discard Package

Lose Information
Respond to Recalls
And this is where it diverges. We're only given one long conditional chain, rather than a conditional statement and an example of that conditional playing out.
Hope that clears things up!
