Outbreaks of Rift Valley fever occur irregularly in East Africa, several years apart. When outbreaks do occur, they kill thousands of cattle. A livestock vaccine against the disease exists but is rarely used. It is too expensive for farmers to use routinely, and since it is not effective until a month after vaccination, administering it after an outbreak begins helps very little. Nevertheless, experts predict that use of the vaccine will increase significantly within the next few years.

Which of the following, if true, provides the strongest justification for the experts’ prediction?

A. Rift Valley fever is spread by mosquitoes, but each outbreak is so widespread that it is impractical to control it by using insecticides.
B. When an outbreak of Rift Valley fever occurs, unaffected countries often refuse to import livestock from the countries affected by the outbreak.
C. It would take less than a month for producers of the vaccine to adjust their production operations to cope with a large increase in demand.
D. Many cattle farmers in East Africa are nomadic or live in remote villages, and such farmers, who have little access to modern veterinary medicine, are particularly hard hit by outbreaks of Rift Valley fever.
E. Recently published research has shown that certain identifiable climatic conditions are almost invariably followed, within two to five months, by an outbreak of Rift Valley fever.

A. Rift Valley fever is spread by mosquitoes, but each outbreak is so widespread that it is impractical to control it by using insecticides.
- Not useful

B. When an outbreak of Rift Valley fever occurs, unaffected countries often refuse to import livestock from the countries affected by the outbreak.
- That might have prompted the farmers to use the vaccine a long time back, why wait ? B is out.

C. It would take less than a month for producers of the vaccine to adjust their production operations to cope with a large increase in demand.
- Out of scope

D. Many cattle farmers in East Africa are nomadic or live in remote villages, and such farmers, who have little access to modern veterinary medicine, are particularly hard hit by outbreaks of Rift Valley fever.

E. Recently published research has shown that certain identifiable climatic conditions are almost invariably followed, within two to five months, by an outbreak of Rift Valley fever.
- It now enables the use of the vaccine ecnomical since you need to use it only after the climate patterns that leads to the outbreak. So farmers do not have to use it routinely, but rather, at certain times of the year.
E it is.

Outbreaks of Rift Valley fever occur irregularly in East Africa, several years apart. When outbreaks do occur, they kill thousands of cattle. A livestock vaccine against the disease exists but is rarely used. It is too expensive for farmers to use routinely, and since it is not effective until a month after vaccination, administering it after an outbreak begins helps very little. Nevertheless, experts predict that use of the vaccine will increase significantly within the next few years.

Which of the following, if true, provides the strongest justification for the experts' prediction?

The reason why the vaccine is rarely used because
1) Expensive
2) Not effective till one month
3) Administrating after the outbreak doesn't add any value.

We need to find out a option which solves one of these problems.

A. Rift Valley fever is spread by mosquitoes, but each outbreak is so widespread that it is impractical to control it by using insecticides.-> Doesn't add any value for any of the reason.

B. When an outbreak of Rift Valley fever occurs, unaffected countries often refuse to import livestock from the countries affected by the outbreak -> Same issue as option A)

C. It would take less than a month for producers of the vaccine to adjust their production operations to cope with a large increase in demand -> Doesn't add any value

D. Many cattle farmers in East Africa are nomadic or live in remote villages, and such farmers, who have little access to modern veterinary medicine, are particularly hard hit by outbreaks of Rift Valley fever -> Doesn't add any value

E. Recently published research has shown that certain identifiable climatic conditions are almost invariably followed, within two to five months, by an outbreak of Rift Valley fever.
-> This option gives a way to to predict that outbreak is going to occur so this option solves the problem # 3 and hence the correct answer.

E. Recently published research has shown that certain identifiable climatic conditions are almost invariably followed, within two to five months, by an outbreak of Rift Valley fever.

The farmers would know the prediction, and use it only after particular climatic conditions. Hence, it will prove to be more useful to farmers now.

Ans is E.

There are two reasons that the vaccine is not used:
1. Expensive
2. Not effective till one month of administering
The experts predict that in spite of the above two reasons, the vaccine would be used. Why?

The correct option should address any/both of the above two issues, i.e. it would suggest that the price would come down and/or that the vaccine can be administered at least one month before the onset of the outbreak.

Only Option E adresses one of these two issues, viz., the second issue. Hence E is the right answer.

(If you are unable to eliminate the other options using the logic described above, please write back again stating which other option do you think adresses one of the two issues.)

A. Rift Valley fever is spread by mosquitoes, but each outbreak is so widespread that it is impractical to control it by using insecticides.
The choice provides more information about the subject but is irrelevant in the strenghtneing or weakening
B. When an outbreak of Rift Valley fever occurs, unaffected countries often refuse to import livestock from the countries affected by the outbreak.
The choice provides more information but does not contribute in addressing the question
C. It would take less than a month for producers of the vaccine to adjust their production operations to cope with a large increase in demand.
the answer choice is irrelevant in addresing the question
D. Many cattle farmers in East Africa are nomadic or live in remote villages, and such farmers, who have little access to modern veterinary medicine, are particularly hard hit by outbreaks of Rift Valley fever.
does not mean that they will be using the vaccination more often in the near future.
E. Recently published research has shown that certain identifiable climatic conditions are almost invariably followed, within two to five months, by an outbreak of Rift Valley fever.
The identification of the pattern of the occurance of the outbreak is beneficial to identifieng the occurnce of the outbreak in the future and the farmers and other impacted groups can administer the vaccine on time and prevent the losses.

E gives a valid reason to believe why there will be an increase in vaccination. Any other option seem too irrelevant.
