Interference can hamper memorization and retrieval. There is retroactive interference, when learning new information makes it harder to recall old information and proactive interference, where prior learning disrupts recall of new information. Although interference can lead to forgetting, it is important to keep in mind that there are situations when old information can facilitate learning of new information. Knowing Latin, for instance, can help an individual learn a related language such as French this phenomenon is known as positive transfer.

Spanish was the language spoken by the first permanent European settlers in North America. Spanish arrived in the territory of the modern United States with Ponce de Leon in 1513. In 1565, the Spaniards, by way of Juan Ponce de Leon, founded St. Augustine, Florida, and as of the early 1800s, it became the oldest continuously occupied European settlement in the continental United States. The oldest city in all of the U.S. territory, as of 1898, is San Juan, capital of Puerto Rico, where Juan Ponce De Leon was its first governor

In the judgment of political scientist Randall Ripley, since 1883 "the candidate for Speaker nominated by the minority party has clearly been the Minority Leader." However, this assertion is subject to dispute. On December 3, 1883, the House elected Democrat John G. Carlisle of Kentucky as Speaker. Republicans placed in nomination for the speakership J. Warren Keifer of Ohio, who was Speaker the previous Congress. Clearly, Keifer was not the Republicans' minority leader. He was a discredited leader in part because as Speaker he arbitrarily handed out "choice jobs to close relatives ... all at handsome salaries." Keifer received "the empty honor of the minority nomination. But with it came a sting -- for while this naturally involves the floor leadership, he was deserted by his [partisan] associates and his career as a national figure terminated ingloriously." Representative Thomas Reed, R-ME, who later became Speaker, assumed the de facto role of minority floor leader in Keifer's stead. "[A]lthough Keifer was the minority's candidate for Speaker, Reed became its acknowledged leader, and ever after, so long as he served in the House, remained the most conspicuous member of his party.
