Input: Article: An earthworm's digestive system consists of a mouth, pharynx, esophagus, crop, gizzard, and intestine. The mouth is surrounded by strong lips, which act like a hand to grab pieces of dead grass, leaves, and weeds, with bits of soil to help chew. The lips break the food down into smaller pieces. In the pharynx, the food is lubricated by mucus secretions for easier passage. The esophagus adds calcium carbonate to neutralize the acids formed by food matter decay. Temporary storage occurs in the crop where food and calcium carbonate are mixed. The powerful muscles of the gizzard churn and mix the mass of food and dirt. When the churning is complete, the glands in the walls of the gizzard add enzymes to the thick paste, which helps chemically breakdown the organic matter. By peristalsis, the mixture is sent to the intestine where friendly bacteria continue chemical breakdown. This releases carbohydrates, protein, fat, and various vitamins and minerals for absorption into the body.

Now answer this question: What does an earthworm eat?

Output: dead grass, leaves, and weeds

Input: Article: Nasser also attempted to maintain oversight of the country's civil service to prevent it from inflating and consequently becoming a burden to the state. New laws provided workers with a minimum wage, profit shares, free education, free health care, reduced working hours, and encouragement to participate in management. Land reforms guaranteed the security of tenant farmers, promoted agricultural growth, and reduced rural poverty. As a result of the 1962 measures, government ownership of Egyptian business reached 51 percent, and the National Union was renamed the Arab Socialist Union (ASU). With these measures came more domestic repression, as thousands of Islamists were imprisoned, including dozens of military officers. Nasser's tilt toward a Soviet-style system led his aides Boghdadi and Hussein el-Shafei to submit their resignations in protest.

Now answer this question: What was the expression of Nasser's reforms on the street?

Output: repression

Input: Article: One wave of the population boom ended abruptly in the mid-1980s, as oil prices fell precipitously. The space industry also suffered in 1986 after the Space Shuttle Challenger disintegrated shortly after launch. There was a cutback in some activities for a period. In the late 1980s, the city's economy suffered from the nationwide recession. After the early 1990s recession, Houston made efforts to diversify its economy by focusing on aerospace and health care/biotechnology, and reduced its dependence on the petroleum industry. Since the increase of oil prices in the 2000s, the petroleum industry has again increased its share of the local economy.

Now answer this question: In the 1990's, what is something Houston did to try to diversify it's economy?

Output:
reduced its dependence on the petroleum industry
