   This conclusion is about a group (Mr. Kelly's students), whereas we want to see a conclusion that is about an individual. Also, this is a valid argument, whereas we want a flawed one.

   Bad Conclusion/Evidence Match1% picked this

   More than half of Milton Elementary School’s students play in the band and more than half of the school’s students sing in the choir.

   This conclusion is about every single person in a group (every student at Milton). We want to see a conclusion that is about an individual. And the evidence should be a fact about a group, but it's really two facts about different subgroups. This argument is flawed for mathematical, Venn diagram reasons. The author fails to consider a significant overlap between these two groups. That's not the same as Whole to Part.

   Why this is right

   This is the only conclusion about an individual, so this problem was a great opportunity to use the Conclusion Match shortcut. This makes a very similar Whole to Part move. Because "#1 ticket seller" is true of Ms. R's whole class, the author assumes that "#1 ticket seller" would be true of one part of Ms. R's class, her top ticket-selling student. We know that Ms. R's class as whole sold more tickets than any other class, but that doesn't mean that the #1 ticket seller in the school was part of Ms. R's class. She may have had a solid group that all did great, but no one who was extraordinary. Meanwhile, Ms. R's class could still beat out a class that had the #1 ticket seller and a bunch of deadbeat other students.
