Let us break this reasoning in simpler terms, so that we can compare with the choices.
People who have habitually slept less than six hours a night(X) and then begin sleeping eight or more hours a night(n(X)) typically begin to feel much less anxious. Therefore, most people who sleep less than six hours a night(X) can probably cause their anxiety levels to fall by beginning to sleep at least eight hours a night(n(X)).
FACT :- People who do X and then start doing n(X), opposite of X, become less anxious.
CONCLUSION :- Therefore,
most people who do X
can probably become less anxious by doing n(X) -
Conclusion talks of MOST and not all, and also talks of a probability, and not a certainty.The reasoning in which one of the following arguments is most similar to that in the argument above?
Quote:
(A) When a small company first begins to advertise on the Internet, its financial situation generally improves. This shows that most small companies that have never advertised on the Internet can probably improve their financial situation by doing so.
Here X is
not advertising, and n(X) becomes
start advertisingFACT :- A small company that did X, and then started doing n(X) improved its financial situation
CONCLUSION :- Therefore,
most small companies that do X
can probably improve their financial situation by doing n(X) -
Conclusion talks of MOST and not all, and also talks of a probability, and not a certainty.Correct
Quote:
(B) Certain small companies that had never previously advertised on the Internet have found that their financial situations began to improve after they started to do so. So most small companies can probably improve their financial situations by starting to advertise on the Internet.
Here X is
not advertising, and n(X) becomes
start advertisingFACT :- Certain small company that did X, and then started doing n(X) improved its financial situation. -
Here we are not talking of all small companies but CERTAIN small companies, so different from the original sentence.CONCLUSION :- Therefore,
most small companies
that do X can probably improve their financial situation by doing n(X) -
Conclusion talks of MOST and not all, and also talks of a probability, and not a certainty., so a bit of change in the format, as the small companies are now not restricted by essential modifier 'that do X', but the meaning remains same. So a very minor change.
However, the FACT does not talk of all small companies, but only a certain, so NOT correct.
Quote:
(C) It must be true that any small company that increases its Internet advertising will improve its financial situation, since most small companies that advertise on the Internet improved their financial situations soon after they first began to do so.
Here X is
not advertising, and n(X) becomes
start advertisingFACT :- Most small companies that did X, and then started doing n(X) improved their financial situation. -
Here we are not talking of all small companies but MOST small companies, so different from the original sentence.CONCLUSION :- Therefore,
all small companies
that do X must improve their financial situation by doing n(X) -
Conclusion talks of ALL and not most, and also talks of a certainty(MUST) , and not a probability.So, neither the FACT nor the conclusion follow the same structure. Hence, NOT correct.
Quote:
(D) Usually, the financial situation of a small company that has never advertised on the Internet will improve only if that company starts to advertise on the Internet. Therefore, a typical small company that has never advertised on the Internet can probably improve its financial situation by doing so.
Usage of USUALLY and ONLY IF makes the choice incorrect.
Quote:
(E) A small company’s financial situation usually improves soon after that company first begins to advertise on the Internet. Thus, most small companies that have never advertised on the Internet could probably become financially strong.
