As advances in medical research and technology have improved the ability of the medical profession to diagnose and treat a wide variety of illnesses and injuries, life spans have increased and overall health has improved. Yet, over the past few decades there has been a steady and significant increase in the rate of serious infections.
Which one of the following, if true, most helps to resolve the apparent discrepancy in the information above?
(A) It remains true that doctors sometimes prescribe ineffective medications due to misdiagnosis.
(B) Life spans have increased precisely because overall health has improved.
(C) The vast majority of serious infections are now curable, although many require hospitalization.
(D) As a population increases in size, there is a directly proportional increase in the number of serious infections.
(E) Modern treatments for many otherwise fatal illnesses increase the patient's susceptibility to infection.

The question asks us to resolve a discrepancy. What is that discrepancy?
On one hand, "life spans have increased and overall health has improved" as medicine and technology have advanced.
On the other hand, "over the past few decades there has been a steady and significant increase in the rate of serious infections."
So, which answer choice explains how both of these things are true at the same time?
Quote:
There are a couple of issues with (D).
Firstly, we have no idea whether the population has increased in the past few decades. Sure, life spans are longer, but other things impact population growth as well (e.g., how many kids people are having). So (D) doesn't necessarily help us explain why infection rates have gone up.
Secondly, the passage talks about the rate of serious infections, whereas (D) talks about the number of serious infections. A rate is generally a proportion, or percentage -- for instance, the number of infections per 100 people. A number, on the other hand, is just a tally of the overall infections. Just because the number of infections increases with population doesn't mean that the rate of infections has changed at all. And in fact, this is exactly what the information in (D) tells us: because there is a "directly proportional" relationship between the increase in population and the number of infections, the rate of infection should stay the same.
(D) doesn't explain why the rate of serious infection has increased, so eliminate (D).
Here's (E):
Quote:
Let's pick this apart: "otherwise fatal illnesses" means that patients would have died if they had not received modern treatments.
Guess what? It's hard to catch a serious infection if you're dead. So, before modern treatments, these patients would not have gotten serious infections! They just would have died.
With modern treatments, though, these patients live to see another day. That's good, but there's a catch -- the treatments increase their vulnerability to infection.
So, (E) explains both part of our discrepancy. Patients receive new treatments and live longer, but they also contribute to the higher rate of infection in the population.
I hope that helps!

we have find the link between usage of modern technology and significant increase in the rate of serious infections associated with its usage/practice
Option E does it...
