People who have habitually slept less than six hours a night and then begin sleeping eight or more hours a night typically begin to feel much less anxious. Therefore, most people who sleep less than six hours a night can probably cause their anxiety levels to fall by beginning to sleep at least eight hours a night.

Question: The reasoning in which one of the following arguments is most similar to that in the argument above?
Options:
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.
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.
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.
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.
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.
