Stimulus

School superintendent: It is a sad fact that, until now, entry into the academically best high school in our district has been restricted to the children of people who were wealthy enough to pay the high tuition. Parents who were previously denied the option of sending their children to this school now only those who live in the neighborhood of the school to attend.

    the residents of the school’s neighborhood tend to

    This answer basically weakens the argument, and an author is never needing to assume something that weakens her argument. We need to assume that residents of the neighborhood are of mixed economic backgrounds and would include non-wealthy parents who were previously denied going to this school because of its high tuition requirement.

  2. Correct80% picked this

    people other than those wealthy enough to have paid the old tuition are able to live in the

    Why this is right

    This gets at the difference the author's plan is assuming. She thinks that if we switch from tuition requirement to neighborhood requirement, it will enable some previously denied parents to get their kids into this school. In order for that to be true, we need to know that some of the residents of the neighborhood are parents who were not wealthy enough to meet the old tuition requirement. If negated, it would say "only people wealthy enough to pay the old tuition are living in this neighborhood", which would weaken because it would mean that even under the new plan, we are still restricting access to the wealthy.

    Skill tested: Necessary Assumption · how this choice captures the argument's function is the move to repeat next time.

  3. Too Strong/Specific: in the majority10% picked this

    It doesn't matter whether most of the district could or couldn't afford the old tuition. Either way the plan could make sense. The author just has to assume that by switching from a tuition requirement to a neighborhood requirement means that at least one local household that couldn't afford the tuition will now be able to send their kid to this school.

  4. Out of Scope0% picked this

    there are no high schools in the district other than the one referred to

    Out of Scope: other schools Too Strong: no This plan is only about this school. It doesn't matter whether there are / aren't other schools in the district.

  5. Irrelevant Quality: desire to attend7% picked this

    (E) speaks to the desire of families to attend the school, which doesn't affect whether or not they actually can under the new requirement. The conclusion isn't saying parents WILL send their kids to this school, just that there will be some parents who previously COULDN'T send their kids to this school and now CAN.
