There is some awesome analysis going on in this thread! I love to see so many people weighing in on a sticky question!
This question is essentially
all about intent. And you should get comfortable with that idea, since you're all going to be spending an inordinate amount of time talking about intent in your first year CrimLaw class!
First, let's address the question type: this is a question stem wording we haven't seen much recently, but
geverett has the right of it in thinking of this as essentially a
Principle-support question. Principle-support questions at their heart, though, are just strengthening questions in more generalized language. And that makes sense for our task here - we want an answer that addresses the gap in logic, but we don't need it to necessarily make the argument air tight (sufficient assumption), and we aren't limited to only those things that absolutely must be true for the argument to work (necessary assumption).
So, on to the core:
PREMISE: toddlers may bite people preventing them from having a toy
CONCLUSION: toddlers are not being malicious when they bite
The very definition of malicious is bad intent! By concluding that toddlers don't have a bad intent in biting, the author is assuming that the example shows some
other intent than a bad one. This is where
(A) leaps to the rescue: if biting is a way to try to solve problems, that's intent! And it matches out example of toddlers biting to get access to a toy. Essentially, this suggests that toddlers aren't biting
for the purpose of being mean (malicious), but rather
for the purpose of solving a problem (getting the toy).
This may not be enough to validly rule out the possibility of malicious intent entirely (maybe the toddlers have both intentions? Maybe some have one and some have the other?), but we aren't looking for a sufficient assumption to make the argument air tight. All we need is a strengthener, an this strengthens the idea that toddlers aren't malicious by providing a possible alternative intent that is at least sometimes present.
Let's break down why the other answers don't fulfill our needs here:
(B) This also offers an alternate intent (getting attention), but this doesn't match our example! These toddlers are biting
to get a toy, not attention.
(C) The discussion above about malicious vs acceptable nails it - these ideas feel related, but they aren't. Maliciousness is all about
intent, while acceptability is about other people's reactions, or the results of an action. On Mars, perhaps Martians find it acceptable to stab a neighbor in the eye to make him suffer if he steals your parking spot. The fact that the culture would find it acceptable in no way changes the malicious intent of the action.
(D)How practically effective biting is as a problem solving strategy, and whether toddlers realize it, has no bearing on what the toddler's
intent is.
(E) Like
(C), this shifts from looking at the
intent to the
result. Whether biting is effective or not has no bearing on what the toddler's original intent was.
I hope this helps clear up a few sticky points on a difficult question with an unusual question stem!
