Hi sherrilynm and lathlee!
We can absolutely discuss questions from June, provided none of us post the question text
So let's see if we can figure out #21 here!
This is a supremely rare question type called Evaluate the Argument, so first things first let me explain what this type is asking and how we can find the correct answer.
Evaluate questions present an argument in the stimulus that fails to be entirely convincing due to some missing or unknown piece of additional information, and the correct answer will either provide that critical piece of knowledge, or present a question the answer to which would give you that necessary info. So like all arguments on the LSAT it pays to be skeptical, and to think about why the author's conclusion could be incorrect! Then to test answers you vary your stance on them—so if an answer asks a "yes or no" type question, you'd test both "yes" and "no"—and see if your opinion of the author's belief changes as your position (your response to the question asked) changes. If so, that's the right answer!
The argument we get in #21 is that the finance minister's country's Doing Business ranking will probably improve, because the government has made filing taxes for small and midsize businesses easier since the last report/rankings came out. Which may sound reasonable at first glance, but there are some holes in that belief! To name a couple:
We don't know what's happened in the country regarding businesses' ability to comply with regulations
(the other component in the rankings), and how compliance is weighted in the rankings
We don't know if small and midsized businesses qualify as one of the "hypothetical businesses" the World
Bank considers in creating the rankings report
We don't know when the next report will be produced and whether the simplified tax filing process will
still exist at that point
So with that degree of uncertainty it's impossible to accept the argument as given. What we'd want to occur if we were looking to improve the argument, or at least make a more informed analysis of its likelihood, is to supply one or more of those pieces of information.
That is, if we knew in response to the first piece I listed above—the compliance part—that compliance with regulations had gotten more difficult, and that compliance was a far more important factor than ease of paying taxes, then it would be reasonable to think this argument is flawed and the country's ranking could actually drop, not improve. So that's a genuinely valuable thing to know, and could serve as the correct answer here, as something like "Has complying with regulations gotten more difficult since the last report?" If the answer is no the conclusion here is better; if the answer is yes then the conclusion seems far less likely (i.e. is worse).
The correct answer, choice D, relates to the second unknown I mention above: do the businesses for which tax filing has been simplified qualify for inclusion in the report/ranking process or not?
Consider the two opposing answers to that question, and what each would do to our opinion of the conclusion:
"Yes": The businesses mentioned ARE smaller than the hypothetical business used to produce the
report. That means the author's conclusion is based on changes that have no bearing on the ranking
process, and is thus a poor argument.
"No": The businesses mentioned are NOT smaller than the hypothetical business used to produce the
report. That means the author's conclusion is based on changes that are relevant to the ranking
process, and is thus a more reasonable argument.
Since testing the two opposite answers to the question posed in D significantly changes our opinion of the author's conclusion, D is the answer that most helps us evaluate the argument.
Note too that this same test applied to the other four answers does nothing to the likelihood of the conclusion, so we can both confirm D's importance and dismiss the other options as irrelevant, all with the same approach!
I'll show you what I mean by analyzing B, which is one that seems to be under some scrutiny here:
"Yes": Compliance by small and midsized businesses HAS increased since tax filing was simplified.
"No": Compliance by small and midsized businesses has NOT increased since tax filing was simplified.
Neither of these matter for the argument for (at least) two reasons: (1) the timing needs to be based on the last ranking report and whether things have changed since then, not since the tax filing change (even if it hasn't changed since the tax filing it could still have changed since the last report, so saying "No" here doesn't necessarily matter at all); (2) more crucially, the rankings are based on "how difficult it is for a business to comply," NOT the frequency with which businesses actually do comply! So whether actual compliance has increased or not isn't the point...we merely need to know how difficult it is to comply and if that difficulty has increased or decreased. So B is something of a shell game trap in that sense: actual compliance is not at all the same as ease of compliance!
I hope that helps!
