Can anyone please explain why A is incorrect?
If you notice there is a gap in the reasoning of the argument. The premise says sth about the treated cases, while the conclusion discusses 'the number of people contract h4n2v'. So we can infer a little bit about the other group, which is the untreated one (total ppl contract = treated + untreated)
The answer to which of the following questions would be most useful in evaluating the health minister’s argument?
(A)Have treatments for the H4N2v virus been successful in curing patients of the ailment?
=> A is wrong simply because it's out of cope, what are we evaluating here? We're evaluating the total numbers of ppl contracting the flu are increasing month-wise, on the basis of the treated case from Jan-Sep. Whether the treatment of the virus is successful in curing the same does not affect the conclusion one bit. If you're picking this answer I think you've attacked the premise instead of the conclusion(B)How many incidences of the H4N2v virus have gone untreated each month?
=> this says something about the other group so i might leave it alone for now(C)Is the H4N2v strain of the flu more contagious than more-common strains of the flu? =>Whether the flu is more contagious than other does not affect the conclusion that 'the number of people contract h4n2v is increasing'
(D)Are any of the patients who were treated for H4N2v in the April-June period still being treated for the virus this month?
=> this is a tempting choice, the 'any of X' structure in CR is pretty suspicious to me (since I made a lot of mistake picking this answer choice). I'll attach a similar 700 level question below fyi. This makes sense but the first one makes even more sense to me, since the stem ask 'most useful', hence they could give us 2 3 make-sense and our job is to find the most sensical one right In B, for example:
J: Treated: 6000, untreated: 1000, total: 7000
F: Treated: 6000, untreated: 600, total: 6600
2 data points are enough to tell us that the total number is not increasing(E)Has the number of diagnosed cases of H4N2v been increasing in neighboring countries? => dont care about the neighboring countries
Here is another Q with the "any of X" (use with caution) - this is from
OG - hope it helps
Following several years of declining advertising sales, the Greenvile Times reorganized its advertising sales force. Before reorganization, the sales force was organized geographically, with some sales representatives concentrating on city-center businesses and others concentrating on different outlying regions. The reorganization attempted to increase the sales representatives' knowledge of clients' business by having each sales representative deal with only one type of industry or of retailing. After the reorganization, revenue from advertising sales increased.
In assessing whether the improvement in advertising sales can properly be attributed to the reorganization, it would be most helpful to find out which of the following?
(A) What proportion of the total revenue of the Greenvile Times is generated by advertising sales?
(B) Has the circulation of the Greenvile Times increased substantially in the last two years?
(C) Among all types of industry and retailing that use the Greenvile Times as an advertising vehicle, which type accounts for the largest proportion of the newspaper's advertising sales?
(D) Do any clients of the sales representatives of the Greenvile Times have a standing order with the Times for a fixed amount of advertising per month?
(E) Among the advertisers in the Greenvile Times are there more types of retail business or more types of industrial business?
