Please Help with Example 6: definition of "these people"

Hello, The video explanation states that the phrase "these people" in the second statement of the stimulus refer to "people who invest in the stock market." I thought it refers not only "people who invest in the stock market," but to "people who invest in the stock market without doing any research of their own." In other words, I incorporated in my diagram of the "these people" the variable "without doing any research of their own." Please help me understand why we ought to omit "without doing any research of they own" from the definition of "these people," especially since had the following statements been general sufficient-necessary principles with a common sufficient variable, the deductions would have affected the answer choice. Is it wrong to define "these people" as "people who invest in the stock market without doing any research of their own," as opposed to defining "these people" as only "people who invest in the sock market"? Thank you

Hi Mazen, thanks for the question.

I see your point about the second statement speaking about those investors who do not research. You could include that term in your diagram to represent their lack of research.

However, I am not sure that this would affect our route to the correct answer. This is because the correct inference comes from a combination of two diagrams.

ISM -most- Not Research
ISM -most- Profit

Because most people who invest in stock market profit and most people who invest in stock market do not research, there must be some overlap between those who do not research and those who profit.

E.g. 1000 people invest in stock market. 501 do not research, 501 profit. This means that at least one person both did not research and profited (aka some)

I hope this helps. Please let me know if you have any other questions.
