E i think...Can someone explain why it isn't E...

(E) A naturally occurring chemical cannot be patented unless its effectiveness as a drug has been rigorously established.
E is totally supporting the words from the Comprehension..Let me quote "however, it must be put through the same rigorous testing program as any synthetic compound, culminating in a published report detailing the chemical’s structure and observed effects."

I think E is wrong simply because Effectiveness is not mentioned in the text. IMO effectiveness is beyond effects.

Naturally occurring chemicals cannot be newly patented once their structures have been published. Before a naturally occurring chemical compound can be used as a drug, however, it must be put through the same rigorous testing program as any synthetic compound, culminating in a published report detailing the chemical's structure and observed effects.
If the statements above are true, which of the following must also be true on the basis of them?
(A) Any naturally occurring chemical can be reproduced synthetically once its structure is known.
(B) Synthetically produced chemical compounds cannot be patented unless their chemical structures are made public.
(C) If proven no less effective, naturally occurring chemicals are to be preferred to synthetic compounds for use in drugs.
(D) Once a naturally occurring compound has been approved for use as a drug, it can no longer be newly patented.
(E) A naturally occurring chemical cannot be patented unless its effectiveness as a drug has been rigorously established.

Canadians now increasingly engage in "out-shopping," which is shopping across the national border, where prices are lower. Prices are lower outside of Canada in large part because the goods-and-services tax that pays for Canadian social services is not applied.
Which one of the following is best supported on the basis of the information above?
(A) If the upward trend in out-shopping continues at a significant level and the amounts paid by the government for Canadian social services are maintained, the Canadian goods-and-services tax will be assessed at a higher rate.
(B) If Canada imposes a substantial tariff on the goods bought across the border, a reciprocal tariff on cross-border shopping in the other direction will be imposed, thereby harming Canadian businesses.
(C) The amounts the Canadian government pays out to those who provide social services to Canadians are increasing.
(D) The same brands of goods are available to Canadian shoppers across the border as are available in Canada.
(E) Out-shopping purchases are subject to Canadian taxes when the purchaser crosses the border to bring them into Canada

I am confused abt the OA

I will go for B. If I am correct, I will post my reasoning later. Please post OA... urgent.

My second thought. Choice B is wrong because it reverse the reasoning If A, then B => if B, then A. Agree with choice D is the correct one, which connect 2 premises together.

+1 for D

Once a naturally occurring compound has been approved for use as a drug (that is the compound has been put on some testing programs and the structure and test results have been published), it can no longer be newly patented (because compound structure has been published, and based on the first sentence it's not allowed to get newly patented).
