Hi SKP220292,Your reading of the paragraph's structure is what's tripping you up, so let's re-read the fifth paragraph carefully. You've treated "the public may not appreciate the pitfalls" as a lead-in, and the three later facts as the real obstacles. But look at how the author frames each piece.
The paragraph opens:
"Public controversy... is driven by several factors." Everything after that - the unappreciated pitfalls, the overly optimistic statements, the small patient count, the single controlled study - is a
factor driving controversy, not a list of obstacles to bringing gene therapy to mainstream medicine. So the three items you liked are being reported as
facts about the current state of the field, not as things standing in the way of adoption.
Now the exact wording of the question matters: it asks what the author
anticipates as a
possible obstacle to introduction to mainstream medicine. That word "anticipates" points forward. Look at the line:
"...the former may not appreciate all the pitfalls and uncertainty that lie in the immediate future." The public grasps the potential but not the dangers - and you can't roll something out to people who don't understand its risks. That forward-looking gap is choice
E.
Why D falls short: "only one controlled study has been published" is a present-day fact about how early the field is - a
symptom of the controversy, not a barrier the author forecasts for public adoption. It answers "what's true right now," not "what could block introduction later."
A quick way to feel the difference:
-
"Few people have test-driven the new car yet" - a fact about the present (like D).
-
"Buyers don't yet realize the brakes can fail" - an obstacle to selling it to them (like E).
The question wants the second kind. That's why
E is the answer.

GMATNinja KarishmaBI need help with Question 1. I cannot comprehend why the public's unawareness of the pitfalls should be an obstacle. I thought the author mentioned their unawareness as a starting context before actually explaining some of the challenges (that the public is unaware of) such as exaggerated claims of biotech firms due to vested interests, small # of actual patients treated, only 1 controlled study etc
So shouldn't the obstacles be any or all of the latter 3 examples (which is why I selected D)? Why is the public's unawareness of the actual challenges be the obstacle? I'm not following the logic here..
