Public Health Official: After several years of vaccinating all of the citizens of this state for Tacitus’ Disease, a highly infectious virus, state hospitals have cut costs by no longer administering this vaccine, starting at the beginning of this year. A state senator defended the position, arguing that after several years with zero incidence of the disease in the state, its citizens were no longer at risk. This is a flawed argument. Our state imports meats and produce from countries with high incidences of diseases for which our country has vaccines. Three years ago, when we reduced the use of the Salicetiococcus vaccines, a small outbreak of Salicetiococcus among young children, fortunately without fatalities, encouraged us to resume use of the vaccines at the previous levels.

The public health official’s statements, if true, best support which of the following as a conclusion?
(A) Young children of the state will be at risk for Tacitus’ Disease.
(B) Some of the meats imported to this state do not have adequate refrigeration during the shipping process.
(C) Tacitus’ Disease is a much deadlier disease than Salicetiococcus, and has a correspondingly higher fatality rate.
(D) No food products produced within the state bear any contaminants that could lead to either Tacitus’ Disease or Salicetiococcus.
(E) The cost of providing all citizens of the state with the Tacitus’ Disease vaccine places an undue burden on the budget of state health agencies.

One common GMAT CR question type is the "find the conclusion" or "find the inference" question. For a full discussion of this question type, as well as an explanation of this question, see:

Great question Mike! My only query is - Would this really be a 600-700 level question, or is it closer to a 700 & above kind of question? Your thoughts? Thank you again!

Dear vishnuns39620,
To be honest, one of the hardest things for me to estimate is the difficulty level of a question I write. Once I write a question, the solution is obvious to me, so that makes it relatively hard to determine its objective difficulty. When we enter questions such as this into the Magoosh product, the computer tallies the cumulative results, and over time that's how we determine the difficulty level of a question, similar to the way GMAC determines difficulty through releasing experimental questions.
When I enter any question on GC, the system, by default, requires me to enter a difficulty level, so basically, I am just taking my best guess --- I often guess conservatively, the lower of two choices. I could see an argument for 600-700 level or for 700+ level. I would be very interested to hear what other users say about the difficulty of this question.
Mike

Thank you Mike! That certainly helps clarify the situation! .

I'm equally curious as to what others have to say about the perceived difficulty of the above question.

Hi Mike,

How can we be so sure that the disease will definitely arrive for young childrer.

The word "will" is very strong in option A.

Thanks,
Jai

Yes, the word "will" is a strong word, but we absolutely know this to be the case. You see, we know that Tacitus’ Disease is "a highly infectious virus," which means people get it very easily. It appears that the only reason Tacitus’ Disease hasn't be active for years is that the entire population has been vaccinated. Keep in mind, people who are vaccinated can carry the virus, but they simply don't get sick from it. In all likelihood, the vast majority of members of this population are passive carriers of the virus, so in all likelihood, the virus is still present in the population. If the authorities stop the vaccinations, then the children born after that time will be without any protection against this highly infectious disease. We can't say for sure that the children will get the disease, but it would seem that the probability is very high. We can say for sure that they are at risk. Any time someone is exposed to any danger without sufficient protection, by definition, they are "at risk." Infectious disease, no vaccination --- that's "at risk."

Does all this make sense?
Mike

Public Health Official:
CONCLUSION- This is a flawed argument that tacitus wont recur.....
PREMISE- Three years ago, when we reduced the use of the Salicetiococcus vaccines, a small outbreak of Salicetiococcus among young children, fortunately without fatalities, encouraged us to resume use of the vaccines at the previous levels. hence similar thing will happen to Tacitus.....

(A) Young children of the state will be at risk for Tacitus’ Disease. correct CONCLUSION.....
(B) Some of the meats imported to this state do not have adequate refrigeration during the shipping process. IRRELEVANT.
(C) Tacitus’ Disease is a much deadlier disease than Salicetiococcus, and has a correspondingly higher fatality rate. COMPARATIVE FATALITY RATE IRRELEVANT.
(D) No food products produced within the state bear any contaminants that could lead to either Tacitus’ Disease or Salicetiococcus. THATS OK... IT COULD COME THROUGH OTHER MEANS...INCORRECT
(E) The cost of providing all citizens of the state with the Tacitus’ Disease vaccine places an undue burden on the budget of state health agencies. BUDGET IS NOT THE KEY ISSUE BUT INCIDENCE OF THE DISEASE... INCORRECT....

I don't know how GMAT ranks questions but I would say this looks sort of a sub 700 level.
Maybe close to 650.

I would say that there are other questions that are in the 700 range like the bold face or long stimulus, with difficult language and lots of relationships and stuff

Any comments on this @Mike McGarry?

Take it easy ok?

' If the authorities stop the vaccinations, then the children born after that time will be without any protection against this highly infectious disease. '

Mike,

I'm a bit confused about this statement. I agree to everything you say but then I don't feel the above statement is necessarily true. For example Smallpox: we don't do vaccines for smallpox anymore because it's not there anymore. Isn't it?

Then how can we say that kids are at risk when the population has been completely vaccinated?

Dear gauravkaushik8591,
I'm happy to respond.

We have to make an important distinction here.

The human race was able to stop vaccinating against small pox because we had been doing it for so long that the disease was declared eradicated everywhere on earth. They stopped administering the small pox vaccine in 1979 when it became clear that there were absolutely no cases of the disease remaining anywhere on the planet. That's why we don't get small pox, even though since 1979 folks have not gotten vaccines for it --- there is absolutely no left from whom we could contract the disease.

Worldwide eradication is the exception, not the rule, in the history of disease. Besides small pox, the only other disease that has been declared eradicated is Rinderpest, a disease that affected cattle and other ungulates. In other words, small pox is the only human disease ever to be eradicated worldwide. Of the 10,000s or 100,000s of diseases that humans can get, this is the only one ever to be eradicated.

Essentially, you are taking the exception and considering it the rule. We are explicitly told in the prompt: "Our state imports meats and produce from countries with high incidences of diseases for which our country has vaccines." We don't know which diseases, but it's certainly reasonable to assume that Tacitus' Disease, a "highly infectious disease," is flourishing somewhere else in the world. In other words, to assume worldwide eradication, you are assuming a 1/100,000 exception took place in this case. We don't know where Tacitus' Disease is active --- maybe it's in the countries from which we import food --- but it must be active somewhere. It would simply be unreasonable to assume that it wasn't.

Does all this make sense?
Mike

Hi Mike,

I have been your keen follower.
The above question is of the 650-700 level.I just wanted to understand in a bit detail about how GMAC actually fixes the level of the question.I mean is it through some sort of Percentile analysis related to that question.

Dear karna2129,
I'm happy to respond.

First of all, please understand: any difficulty estimates given here in GMAT Club are complete guesses, pure estimates. Invest them with absolutely no validity whatsoever. I wrote this particular question, but is it a 650 question? a 700 question? To be perfectly frank, from the question itself, I have no idea. Absolutely no one can look at a question and predict with complete precision the level of difficulty of a question.

Now, for this particular question, I happen to know that since we released it in our product in Magoosh, almost 2000 Magoosh users have answered it, and approximately 44.7% of them have answered the question correct. Now, are Magoosh users a good estimate of the entire GMAT taking population? I don't know. I do know that when GMAC tests experimental questions, it gets tens, even hundreds, of thousands of responds: by comparison, fewer than 2000 responses is a relatively small sample.

Let's assume that, of all test takers, 44.7% of them got the question correct. Well, looking at the GMAT percentiles:
http://magoosh.com/gmat/2013/gmat-score-percentiles/
If 44.7% get the question right --- that's a percentile that corresponds to about a 560 GMAT score. This is a rough idea. One might call this a "560-question," although that is problematic.

Notice, that even with a great deal of numerical information, the upper reaches of the percentile information become very tricky, because even when people are randomly guessing on five-choice multiple choice, they still have a 25% chance of guessing correctly. If only, say, 3% of the population can actually compute the answer to a question, this small percentage will be hard to separate from all the random guesses who simply, by pure chance, happened to guess correctly. One needs some very sophisticated statistical analyses to make discerning distinctions in that upper part of the Bell Curve.

Keep in mind --- this entire idea of attaching a particular point value to a question is highly suspect, at a number of levels. Notice that GMAC itself doesn't even touch this with a ten-foot pole. GMAC has absolutely no interest in assigning point values to questions, because it's such an inherently dubious business. It's one of these ideas to which student attach considerable importance without fully understanding how logically shifty it is, so we folks who work for private companies and answer student question have to discuss it, and in doing so, we convey the mistaken impression that the entire idea holds any water at all. It's an idea that has gained a great deal of currency, not because it's inherent sound, but only because students mistakenly imagine that such information is critically helpful to them. In any teacher-student relationship, ideas that arise primarily on the student side rather than the teacher side overwhelmingly tend to be considerably less helpful in the long run to the students than they might have imagined. Just because an idea is popular doesn't mean it's good!

For example, suppose one gets this question and questions as hard as this correct, and suppose one gets, say, a 27 on Verbal. Well, as you well know, a 27 on Verbal could be paired with a 15 on Quant or with a 51 on Quant --- those different Quant scores would have virtually nothing to do with one's verbal abilities, but would result in vastly different GMAT scores. If we start comparing difficulty on Verbal vs. Quant questions, we are comparing apples to oranges, because different segments of the population excel at these different tasks. Furthermore, one's GMAT score is not at all a simple thing to understand: the GMAT uses a mind-bogglingly difficult algorithm in the Computer Adaptive Testing, and those of us without Ph.D.s in Psychometrics could not hope to understand all the nuances, even if we were allowed to see the process they are using. (In fact, that entire algorithm is proprietary knowledge of GMAC, and those of us on the outside know nothing about it!) One's GMAT score in fact depends both on the difficulty of the questions one gets correct and the difficulty of the questions one gets wrong: that's part and parcel of how the CAT calculates your score. If one gets all the questions of this difficulty correct, vs. half of them right and half of them wrong, those two scenarios would result in very different scores. Performance on one question, in isolation, is virtually meaningless. See:
http://magoosh.com/gmat/2012/what-is-th ... tive-test/

I would say: a discerning approach would be to abandon any thought of attaching particular GMAT-scores to particular questions. Through keeping a log of your own mistakes, get familiar with the patterns and with what is hard for you. Knowing your own weaknesses is considerably more important than knowing overall statistical trends.

Does all this make sense?
Mike

Hi Mike,
I call upon your wisdom once more.
I see that the answer is A, as it's the most likely one.
My questions is, why do we eliminate D?
According to the health official, "Our state imports meats and produce from countries with high incidences of diseases for which our country has vaccines. "... I agree that he's not listing the disease, but can't we infer this?
Also, since he is referring to food, but only to imported food, and not saying that the food produced inside the country can carry the disease, doesn't this actually tell us that that's not the case?

Dear ronr34,
I'm happy to respond.

First of all, notice that (D) is extreme. "No food products" --- none at all! This would be false even if only one odd product out of 10,000 had some traces of one virus or the other. It's very hard to conclude something so extreme. In general, on GMAT CR and RC, beware of all-inclusive statements --- it's very hard to infer that such statements are true.

It seems more or less reasonable to infer that homegrown food products are, on average, safer than the imported food products. It seems more or less reasonable to assume that the incidence of viral infection is far less for these homegrown products, but to infer that they are 100% safe and entirely pure, completely virus free --- that's a bit too much. That's very typical of a wrong answer pattern on the GMAT CR --- take something otherwise perfectly reasonable, and make extreme so that it's no longer reasonable.

Also, technically speaking, we know zilch about the homegrown food. The Public Health Official seems very concerned about imported food from places with high incidence of the disease, but technically, he doesn't make any comparison at all to food grown in the state, and any comparison is completely implicit. Even if (D) were not so extreme, it still would not have the character of a good GMAT inference, because there is a way that we are guessing in the dark. If something is not mentioned at all, either in the positive or the negative, we are on much less sure grounds when we make any inference about it.

A good GMAT inference or conclusion we can draw is something absolutely unambiguous, something which we can conclude with absolutely no doubts. If something wasn't even mentioned, we can have doubts.

Does all this make sense?

the answer to this question seems to be assuming something. no where in the passage we have been told that the vaccination of Tacitus' Disease is for "children" !! the passage has talked about "vaccinating all of the citizens of this state for Tacitus' Disease" ------> this does not mean that we need to vaccinate just the "children" . who knows that this particular vaccination of "Tacitus' Disease" is administered to only ADULTS !!!!
though is selected A;however i feel that A should have read as: citizens of the state will be at risk for Tacitus' Disease

My friend, this is a subtle thing about the GMAT CR. You don't need to have the detailed knowledge of a topic that only a specialist would have --- in this case, only, say, the detailed knowledge of a molecular biologist who studied vaccines. That's the kind of outside knowledge that you absolutely don't need. BUT, you do need to have general outside knowledge, the kind of knowledge that most adults would have and take for granted. See:
http://magoosh.com/gmat/2014/gmat-criti ... knowledge/
Here, it's absolutely essential that you have the kind of knowledge about vaccines that virtually every parent in the industrialized world has, and that any pediatrician would tell you: almost all vaccines are given in early infancy. If there's any risk at all that children could get the disease, then of course we would want to inoculate them as soon as possible. The only vaccines I know that are given in adult life are (a) those that children would be quite unlikely to get (e.g. Hepatitis C, a risk for drug use and unprotected sexual relations), or (b) something that needs to be updated regularly in a booster shot (flu, tetanus). The passage clearly indicates that children would be susceptible to these diseases, and it doesn't even mention the issue of booster shots. If children are vulnerable to the disease, why on earth would any responsible medical professional delay the vaccine until adulthood?

The GMAT CR loves to prey on folks who think that CR questions depend on absolutely no outside knowledge of any kind, including any obvious real world fact. If your imagination and critical thinking runs in directions that are not supported by the real world, this tendency will pose a problem in the GMAT CR, in your B-school application, and in your work as an MBA in your career. Read that blog article for suggestions.

Does all this make sense?

mike thanks for pointing out this. in fact i have been an ardent follower of this concept; however, at times i fail to understand when the same thing is said or written in polar opposite way to eliminate some valid answer answer choices in other CR
BTW wish you a happy new year 2015 !!

Public Health Official: After several years of vaccinating all of the [#permalink]

This post was
BOOKMARKED
Public Health Official: After several years of vaccinating all of the citizens of this state for Tacitus' Disease, a highly infectious virus, state hospitals have cut costs by no longer administering this vaccine, starting at the beginning of this year. A state senator defended the position, arguing that after several years with zero incidence of the disease in the state, its citizens were no longer at risk. This is a flawed argument. Our state imports meats and produce from countries with high incidences of diseases for which our country has vaccines. Three years ago, when we reduced the use of the Salicetiococcus vaccines, a small outbreak of Salicetiococcus among young children, fortunately without fatalities, encouraged us to resume use of the previous vaccines.

The public health official's statements, if true, best support which of the following as a conclusion?

A.Young children of the state will be at risk for Tacitus' Disease.
B.Some of the meats imported to this state do not have adequate refrigeration during the shipping process.
C.Tacitus' Disease is a much deadlier disease than Salicetiococcus, and has a correspondingly higher fatality rate.
D.No food products produced within the state bear any contaminants that could lead to either Tacitus' Disease or Salicetiococcus.
E.The cost of providing all citizens of the state with the Tacitus' Disease vaccine places an undue burden on the budget of state health agencies.

Senator - Stop the vaccination since citizen are no longer at risk. Since several years zero incidence.
Author - Opposes the senator with below facts
1. State imports meat and produce from countries with high incidences of diseases for which our country has vaccines.
2. Three years ago, when we reduced the use of the Salicetiococcus vaccines, a small outbreak of Salicetiococcus among young children, fortunately without fatalities, encouraged us to resume use of the previous vaccines.

Possible Conclusion :
Citing authors argument, we can say author would like to say citizens are at similar risk, and we should not stop vaccination.

POE
A.Young children of the state will be at risk for Tacitus' Disease.
Yes, Similar pattern. Keep this aside .

B.Some of the meats imported to this state do not have adequate refrigeration during the shipping process.
Nice fact, this is not what author would like to conclude.

C.Tacitus' Disease is a much deadlier disease than Salicetiococcus, and has a correspondingly higher fatality rate.
Nice fact, this is not what author would like to conclude. Not supported by argument.

D.No food products produced within the state bear any contaminants that could lead to either Tacitus' Disease or Salicetiococcus.
Incorrect does not support the conclusion that author likely to present.

E.The cost of providing all citizens of the state with the Tacitus' Disease vaccine places an undue burden on the budget of state health agencies.
this is not the stand taken bu author and hence cannot be a conclusion.

Option A is best among given options
