This is a trick used by GMAT. What you need to understand for these questions is the concept of necessary and sufficient conditions.
Immunization is one of the things that ensure the health of children (there are other factors such as nutrition, clean environment etc).
The author assumes that immunization is sufficient to ensure the health of children. That nothing else is needed. He says, "When all children are properly immunized,
we will be able to ensure their health." That is his incorrect assumption. Answer is (E)
Let me come to why (C) is not the answer.
We know he believes that when all children all properly immunized, we will be able to ensure their health. But do we know what he thinks will happen if they are not immunized? Does he think most of them will fall victim to disease? Does he think they will be vulnerable to disease? We do not know. All we know is that he is assuming that if you vaccinate children, they will remain healthy. He is not assuming anything about what will happen if you do not vaccinate the children.
Hi karishma
You have been posting excellent explanations for this question since 2010 almost 3 years..........
"Immunization is one of the things that ensure the health of children (there are other factors such as nutrition, clean environment etc).
The author assumes that immunization is sufficient to ensure the health of children."
this is quoted from your above post.... Pls explain on the basis of the above quoted explanation, it means that If not immunized , they will not be immune to disease......Which is option C
Is it because of the transition in word " Health" to " Disease" that we consider the answer to be wrong or the negative answer...For rookie test takers like me..C and E are very closely placed...Difficult to understand implied meaning of both....In 2 min time its difficult to differentiate between the two..
Pls explain how to distinguish between C and E and eliminate option C.
I say, 'If you keep eating like this, you will not lose weight.'
What does this imply? That I believe that if you keep eating, you will not lose weight. What do you think I believe will happen if you don't eat like that? You can't say! I may believe that you will lose weight right away. I may believe that you will need to diet and exercise and then you will lose weight. I haven't said anything about what will happen if you don't eat like that. I have only told you what I believe will happen if you do keep eating like that.
The author says 'When all children are properly immunized, we will be able to ensure their health.'
He doesn't say what will happen when all children are not properly immunized. Perhaps he believes very few will fall sick or some will fall sick or many will fall sick etc.
whereas E clearly gives an assumption he is making. He says that when children are immunized, they will be healthy i.e. no other factors affect the health of the children. That immunization is enough to ensure the health.
Try to negate (E) - Immunization is not the only precaution necessary to guarantee a child's health. You need other things too.
Can the author's conclusion still hold? No. He is concluding that immunization guarantees health.
When you negate E, the conclusion falls. Hence, it is the assumption.
