Despite the debatable strategic success and the operational failure of the descent on Rochefort, William Pittwho saw purpose in this type of asymmetric enterpriseprepared to continue such operations. An army was assembled under the command of Charles Spencer, 3rd Duke of Marlborough; he was aided by Lord George Sackville. The naval squadron and transports for the expedition were commanded by Richard Howe. The army landed on 5 June 1758 at Cancalle Bay, proceeded to St. Malo, and, finding that it would take prolonged siege to capture it, instead attacked the nearby port of St. Servan. It burned shipping in the harbor, roughly 80 French privateers and merchantmen, as well as four warships which were under construction. The force then re-embarked under threat of the arrival of French relief forces. An attack on Havre de Grace was called off, and the fleet sailed on to Cherbourg; the weather being bad and provisions low, that too was abandoned, and the expedition returned having damaged French privateering and provided further strategic demonstration against the French coast.

How did the British invaders respond to the arrival of French relief forces?
Output: the expedition returned having damaged French privateering

Input: Article: Primary sex characteristics are those directly related to the sex organs. In males, the first stages of puberty involve growth of the testes and scrotum, followed by growth of the penis. At the time that the penis develops, the seminal vesicles, the prostate, and the bulbourethral gland also enlarge and develop. The first ejaculation of seminal fluid generally occurs about one year after the beginning of accelerated penis growth, although this is often determined culturally rather than biologically, since for many boys first ejaculation occurs as a result of masturbation. Boys are generally fertile before they have an adult appearance.

Now answer this question: What activity often results in a boy's first ejaculation?

Output: masturbation

Here is a question about this article: As civil wars engulfed several Central American countries in the 1980s, hundreds of thousands of Salvadorans fled their country and came to the United States. Between 1980 and 1990, the Salvadoran immigrant population in the United States increased nearly fivefold from 94,000 to 465,000. The number of Salvadoran immigrants in the United States continued to grow in the 1990s and 2000s as a result of family reunification and new arrivals fleeing a series of natural disasters that hit El Salvador, including earthquakes and hurricanes. By 2008, there were about 1.1 million Salvadoran immigrants in the United States.
What is the answer to this question: Are the Salvadorans a large population in the U.S.?
****
So... the Salvadoran immigrant population in the United States increased nearly fivefold from 94,000 to 465,000.
