Pretty much understand everything except one thing, please help me 7Sage wizards

Most opera singers who add demanding roles to their repertoires at a young age lose their voices early. It has been said that this is because their voices have not yet matured and hence lack the power for such roles. But young singers with great vocal power are the most likely to ruin their voices. The real problem is that most young singers lack the technical training necessary to avoid straining their vocal cords—especially when using their full vocal strength. Such misuse of the cords inevitably leads to a truncated singing career.

E)Most young opera singers who sing demanding roles strain their vocal cords

Young Opera singers -most> loose voice

Young Opera singers -most> lack tech training to avoid loosing voice

Is it possible to add a notes section for the blind review process so we can track our reasoning and be able to compare it after submitted to the right answers. Also is it possible to allow us to edit previously entered notes. Thanks

Say for example, I am reviewing a question and have an additional insight that I would like to add. It seems that I can only add a new notes instead of editing my preexisting note.

If I am using notes to keep my a wrong answer journal centralized on 7sage, then I would prefer to edit existing notes. Can you please add fix this feature?

Salespeople always steer customers toward products from which they make their highest commissions, and all salespeople in major health stores work on commission. Hence, when you buy vitamin supplements in a major health store, you can be sure that the claims the salespeople make about the quality of the products are inaccurate.

Obviously this is an ad hominem. I know that. But we are taught to apply a two step test: descriptively accurate and does it describe the flaw.

the right answer choice?

infers that some claims are inaccurate solely on the basis of the source of those claims

translation: 1-99 of claims are inaccurate, solely on the basis of the source of those claims.

how is this descriptively accurate? the argument assumes because sales people have specific incentives, salespeople are not telling the full truth.

the argument never says SOME claims are inaccurate, instead it says THE CLAIMS ARE INACCURATE. how the hell am I supposed to see the invisible some? Also the argument never says they are liars because they are sales people, it says it's because they work on commission.

someone tell me how I am wrong. I feel like im getting punished for being detail oriented.
