Hi VenkataSai,You've read the first premise correctly: added
sugar is the stated cause of high blood pressure, and swapping in stevia removes that specific cause. Your logic is fine up to that point.
The slip is in how far the
conclusion actually reaches. Look at its exact words:
"...can now safely indulge themselves in them without worrying about the negative consequences to their health."That is a much bigger claim than "their blood pressure is safe." It says these
manufactured foods carry
no health downside at all. Removing sugar only closes the blood-pressure risk - it says nothing about the
other things that come with manufactured foods (additives, preservatives, etc.). Those aren't outside knowledge you're smuggling in; they're the ordinary contents of any manufactured product, and the conclusion promises safety from
all health consequences, not just the sugar one.
So there's a gap: sugar is gone, but is the rest of the product safe? That's the exact hole
B plugs - it confirms the stevia products follow FDA rules on harmful additives and preservatives, so nothing
else in them threatens health either. That's what earns the word "safely."
On your point that "sugar could also be manufactured without harmful substances" - the products no longer contain added sugar, so that isn't what we need reassurance about; we need reassurance about the food they
are eating now.
Turn one knob to feel it:- If the conclusion had said "...their blood pressure will be fine," then a stevia-and-blood-pressure fact (like C) would be enough.
- But it says "without worrying about
the negative consequences to their health" - broad. Now you must rule out every other risk in the food, which is exactly what B does.
C only re-confirms the one risk we already fixed; the broad conclusion needs the
remaining risks ruled out, and that's B.
Answer: BVenkataSai
The passage clearly mentions that sugar is the main reason for obesity ( not the preservatives or other added elements). So when sugar is replaced with stevia, and asking obese people to enjoy it without worrying about health issues, then we are indirectly telling them that stevia will not bring the health risks that sugar does. Preservatives or other additives are completely out of scope here. There is a chance that sugar is also being manufactured without the addition of harmful substances. So how come this irrelevant option-B is the answer?
