### HideShow timer Statistics

A public health officer reported that 60 % of the children at summer school have never had the measles or chicken pox and that of this 60 %
not one child has ever been observed to eat the cheese served in the
school lunches. From this he concluded that children who abstain
from cheese products will protect themselves from most childhood diseases.

Each of the following , if true, would strenghthen the official's argument except:

a) medically speaking , whatever serves to inhibit measles and chicken pox will generally inhibit the entire spectrum of childhood diseases.

b) the observations the official carried out were extremely accurate and all those observed to abstain from cheese at school did, in fact, abstain.

c)the children's eating habits are the same at school as anywhere lese and those who abstain from cheese products at school do so in general.

d) recent research has pointed to a deficiency in cheese products as one of the major causes of measles and chicken pox infections.

e) most cheeses and cheese products harbor bacteria that are known to be causative agents for many childhood diseases, such as measles and chicken pox.

D for me.
Other choices strengthen the conclusion, while in D deficiency means lack of cheese, so if lack of cheese causes childhood diseases, then it's not true that abstention from cheese products will protect children from most childhood diseases.

By the way, I did this without actually knowing the meaning of measles and chicken pox...

1) A public health officer reported that 60 % of the children at summer school have never had the measles or chicken pox

2) Of this 60 % not one child has ever been observed to eat the cheese served in the school lunches.

3) From this he concluded that children who abstain from cheese products will protect themselves from most childhood diseases. <--

Each of the following , if true, would strenghthen the official's argument except:

a) medically speaking , whatever serves to inhibit measles and chicken pox will generally inhibit the entire spectrum of childhood diseases.
- But we're not told here it's cheese products that inhibits measles and chicken pox. A is out.

b) the observations the official carried out were extremely accurate and all those observed to abstain from cheese at school did, in fact, abstain.
- Still does not tie cheese product to inhibit most childhood disease

c)the children's eating habits are the same at school as anywhere else and those who abstain from cheese products at school do so in general.
- Same problem as above

d) recent research has pointed to a deficiency in cheese products as one of the major causes of measles and chicken pox infections.
- If it's a deficiency, then eating cheese products won't get you measles/chicken pox

e) most cheeses and cheese products harbor bacteria that are known to be causative agents for many childhood diseases, such as measles and chicken pox
- this is the answer we need. We're told there's a causative agent in cheese products for many childhood disease, so the conclusion is strengthened.

E it is.

ywilfred, we're searching for what DOESN'T strengthen the argument (ALL except or in other words we're searching for the only one to weaken the argument)

How can "deficiency in Cheese product" mean "lack in Cheese"? It could be anything? I am not convinced with (D). Please clarify..

let me clearify this:

in the passage it is mentioned that "children who abstain from cheese products will protect themselves from most childhood diseases", which means children who donot eat chease product are free from the disease. but D says lack of cheese products is the reason for the diseases. therefore, D, except all, doesnot support the conclusion of the passage.

(d) recent research has pointed to a deficiency in cheese products as one of the major causes of measles and chicken pox infections.

I took it other way round. Makes sense. Thanks MA for clarifying.
