13. Five years ago, during the first North American outbreak of the cattle disease CXC, the death rate from the disease was 5 percent of all reported cases, whereas today the corresponding figure is over 18 percent. It is clear, therefore, that during these past 5 years, CXC has increased in virulence.

Which one of the following, if true, most substantially weakens the argument?

(A) Many recent cattle deaths that have actually been caused by CXC have been mistakenly attributed to another disease that mimics the symptoms of CXC.
(B) During the first North American outbreak of the disease, many of the deaths reported to have been caused by CXC were actually due to other causes.
(C) An inoculation program against CXC was recently begun after controlled studies showed inoculation to be 70 percent effective in preventing serious cases of the illness.
(D) Since the first outbreak, farmers have learned to treat mild cases of CXC and no longer report them to veterinarians or authorities.
(E) Cattle that have contracted and survived CXC rarely contract the disease a second time.

A.

There are two ways to weaken the argument.
1. if the deathes reported were actually misreported as in A.
2. if the number of reports five years ago was substantiaslly higher with few dathes and no of reports now is subtantially low with high deaths. for example:
five years ago: no of reports=400, % death= 5% i.e. no of death = 20.
now: no of reports=100, % death= 18% i.e. no of death = 18.

the question provides information about the first inforation. therefore, A should be correct.

D.

C actually strengthen the statement. Some of the cases are attributed to other diseases, implying the actual increase is even more.

Same with B. meaning the actual % should be less than 5%.. does not explain the increase.
D is straight forward (I guess!!)..The reported cases are mostly severe cases, increasing % cattle died. (cattle died/cases reported)

1) 5 yrs ago, the death rate from cxc was 5% of all reported cases

2) Today, the figure is over 18% of all reported cases.

3) During past 5 years, CXC has increased in virulence. <-- conclusion

(A) Many recent cattle deaths that have actually been caused by CXC have been mistakenly attributed to another disease that mimics the symptoms of CXC.
- doesn't streghten the argument

(B) During the first North American outbreak of the disease, many of the deaths reported to have been caused by CXC were actually due to other causes.
- Doesn't strenghten the argument

(C) An inoculation program against CXC was recently begun after controlled studies showed inoculation to be 70 percent effective in preventing serious cases of the illness.
- Still can't explain the large perentage

(D) Since the first outbreak, farmers have learned to treat mild cases of CXC and no longer report them to veterinarians or authorities.
- If so, then only deaths due to CXC are reported.

(E) Cattle that have contracted and survived CXC rarely contract the disease a second time.
- Not important.

D is the best option. If only deaths due to cxc is reported, then the figure is not accurate since mild cases are nto included when the % is computed in the study.

A would lead to the conclusion that the number of reported deaths because of CXC is less than the actual number.

D should be it

Agree with D...Who knows what the farmers might have thought about serious cases without reporting?
