The correct answer is:
The author's purpose for the allusion is to emphasize how seriously the relationship is doomed.
Romeo and Juliet was a tragic story. Two star-crossed lovers who could not be together, and have a sustaining relationship. Comparing Sasha and Karl to this really shows how these two face a similar proposition. Their relationship is doomed. They can't be together like Romeo and Juliet could not be together.
1. The difference between a bond and a stock is that stocks are shares that represent ownership in a company, and bonds are a form of long-term debt where you invest your money (essentially, a business loans money FROM you and promises to pay it back by a certain date). You should see a sizable return at the end of a bond's maturity date.
2. What makes a mutual fund an attractive investing option is that it is a diversified portfolio of different investments, such as bonds and stock. Since it is more spread out there is less overall risk.
3. A commercial bank differs from a Savings and Loan (S&L) association because S&L associations are more focused on residential mortgage, whereas commercial banks work more with large businesses.
4. A commercial bank differs from a credit union because most credit unions are not-for-profit establishments with their earnings paid back in the form of lower loan rates and higher savings rates. Commercial banks are for-profit and whatever they earn are paid back to stockholders only.
