Problem: To Kill a Mockingbird:

As a Southern Gothic novel and a Bildungsroman, the primary themes of To Kill a Mockingbird involve racial injustice and the destruction of innocence. Scholars have noted that Lee also addresses issues of class, courage, compassion, and gender roles in the American Deep South. The book is widely taught in schools in the United States with lessons that emphasize tolerance and decry prejudice. Despite its themes, To Kill a Mockingbird has been subject to campaigns for removal from public classrooms, often challenged for its use of racial epithets.

Problem: San Diego:

The city's primary commercial airport is the San Diego International Airport (SAN), also known as Lindbergh Field. It is the busiest single-runway airport in the United States. It served over 17 million passengers in 2005, and is dealing with an increasingly larger number every year. It is located on San Diego Bay three miles (4.8 km) from downtown. San Diego International Airport maintains scheduled flights to the rest of the United States including Hawaii, as well as to Mexico, Canada, Japan, and the United Kingdom. It is operated by an independent agency, the San Diego Regional Airport Authority. In addition, the city itself operates two general-aviation airports, Montgomery Field (MYF) and Brown Field (SDM). By 2015, the Tijuana Cross-border Terminal in Otay Mesa will give direct access to Tijuana International Airport, with passengers walking across the U.S.Mexico border on a footbridge to catch their flight on the Mexican side.

Problem: Electric motor:

Application of electric motors revolutionized industry. Industrial processes were no longer limited by power transmission using line shafts, belts, compressed air or hydraulic pressure. Instead every machine could be equipped with its own electric motor, providing easy control at the point of use, and improving power transmission efficiency. Electric motors applied in agriculture eliminated human and animal muscle power from such tasks as handling grain or pumping water. Household uses of electric motors reduced heavy labor in the home and made higher standards of convenience, comfort and safety possible. Today, electric motors stand for more than half of the electric energy consumption in the US.

Where didn't electric motors improve convenience and safety?
