In this task, you're given an article and an answer. Your task is to generate the question for the answer based on the given article.

Input: Consider Input: Article: Science Daily (Apr. 27, 2008)-- Dutch ecologist Roxina Soler and her colleagues have discovered that subterranean and aboveground herbivorous insects can communicate with each other by using plants as telephones. Subterranean insects issue chemical warning signals through the leaves of the plant. This way, aboveground insects are warned that the plant is already "occupied". Aboveground, leaf-eating insects prefer plants that have not yet been occupied by subterranean root-eating insects. Subterranean insects send out chemical signals through the leaves of the plant, which warn the aboveground insects about their presence. This messaging makes it possible for spatially-separated insects to avoid each other, so that they do not compete for, the same plant. In recent years it has been discovered that different types of aboveground insects develop slowly if they feed on plants that also have subterranean insects and 'vice versa . It seems that a mechanism has developed through natural selection, which helps the subterranean and aboveground insects to communicate with each other. This avoids unnecessary competition. Through the "green telephone lines", subterranean insects can also communicate with _ , namely the natural enemy of caterpillars . Parasitic wasps lay their eggs inside aboveground insects. The wasps also benefit from the signals sent by the leaves, as these help them find more insects for their eggs. The communication between subterranean and above- ground insects has only been studied in a few systems. It is still not clear how widespread this phenomenon is, say the researchers.
Answer: By sending signals through the leaves.

Output: How do subterranean and aboveground insects communicate with each other?

Input: Consider Input: Article: BEIJING -- The rescue operations at a coal mine accident have ended with 105 miners dead. The State Council has organized an investigation team to probe into what caused the disaster in the city of Linfen, North China's Shanxi Province. Preliminary investigations show the illegal mining of an unauthorized seam , and the number of miners who had been sent down the shaft far exceeded its capacity. This mine was found to have long ignored the rules to steal state coal, and did not have a list of miners employed to check the number of miners missing after the accident. How did such a coal mine get all the necessary licenses for production? How did it pass the three safety inspections the local government organized last month? In response to this disaster, the Shanxi governor promised to set up hotlines for people to report illegal coal mines and rewards as high as 100,000 yuan for _ We appreciate the action this governor has taken to solving the coal mining problems, and we believe that the reporting scheme will help to stop the existence of illegal coal mines. But at the same time we have reason to question how governments at various levels supervise these mines. The sad fact that such a mine with serious safety problems could pass three consecutive local government safety inspections in a month is enough to tell us how ineffective the safety inspections were. What if these inspections were just a formality ? What if the inspectors were bribed by the mine owners to turn a blind eye to the safety dangers? We can well imagine what would happen if reports about mine problems were handled by such officials. So a thorough probe must find out who are responsible for the death of so many miners. A real safety inspection and management system must be established to guarantee that safety dangers will be removed.
Answer: The workers didn't operate properly.

Output: What is NOT one of the causes of this coal mine accident?

Input: Consider Input: Article: prefix = st1 /Mauritius, with its full name the Republic of Mauritius, an island country, lies 1,200 miles off the southeastern coast of Africa, and just east of Madagascar, another African island country, which is larger by far thanMauritius. It covers 788 square miles and has a population of 1,00,000, about 750.000 Indians, 300,000 Chinese and 20,000 Whites included. They are living together peacefully, although they share such different beliefs as Hindu, Roman Catholic, Muslim and so on. The country can be divided into many parts with different climate all because of its peculiar terrains . In the center there are volcanoes several thousand feet high, and 90% of its arable land is covered with sugarcane. There are no people living on the island before the Dutch landed on it in 1638. The Dutch _ it in 1710, and five years later, the French came and succeeded in planting sugarcane there. It was conquered byBritainin 1818. As a result, its official language is English. The main big cities are Beau - Bassin and Mahebourg, withPort Louisas its capital. Mauritius has many rare and unique animals, such as the snakes, parrots and lizards. The giraffe is a type of animal with a very long neck and legs and yellow skin with dark spots. It is the tallest of all living animals. Mauritius was extremely poor when it declared its independence in 1968. In the past ten years, obvious economic prosperity has shown itself in this island country. Nowadays its business, culture and tourism are developing rapidly. Every year, thousands of millions of people rush there to enjoy the silver sand beach and song and dance performances with native national characters.
Answer: The French and British people
Output: Who succeeded in planting sugarcane?
