Question: Nouns are also inflected for number, distinguishing between singular and plural. Typical of a Slavic language, Czech cardinal numbers one through four allow the nouns and adjectives they modify to take any case, but numbers over five place these nouns and adjectives in the genitive case when the entire expression is in nominative or accusative case. The Czech koruna is an example of this feature; it is shown here as the subject of a hypothetical sentence, and declined as genitive for numbers five and up.

Answer: unanswerable
Question: By 1959, American observers believed that the Soviet Union would be the first to get a human into space, because of the time needed to prepare for Mercury's first launch. On April 12, 1961, the USSR surprised the world again by launching Yuri Gagarin into a single orbit around the Earth in a craft they called Vostok 1. They dubbed Gagarin the first cosmonaut, roughly translated from Russian and Greek as "sailor of the universe". Although he had the ability to take over manual control of his spacecraft in an emergency by opening an envelope he had in the cabin that contained a code that could be typed into the computer, it was flown in an automatic mode as a precaution; medical science at that time did not know what would happen to a human in the weightlessness of space. Vostok 1 orbited the Earth for 108 minutes and made its reentry over the Soviet Union, with Gagarin ejecting from the spacecraft at 7,000 meters (23,000 ft), and landing by parachute. The Fédération Aéronautique Internationale (International Federation of Aeronautics) credited Gagarin with the world's first human space flight, although their qualifying rules for aeronautical records at the time required pilots to take off and land with their craft. For this reason, the Soviet Union omitted from their FAI submission the fact that Gagarin did not land with his capsule. When the FAI filing for Gherman Titov's second Vostok flight in August 1961 disclosed the ejection landing technique, the FAI committee decided to investigate, and concluded that the technological accomplishment of human spaceflight lay in the safe launch, orbiting, and return, rather than the manner of landing, and so revised their rules accordingly, keeping Gagarin's and Titov's records intact.

Question: Agriculture and horticulture seek to optimize the capture of solar energy in order to optimize the productivity of plants. Techniques such as timed planting cycles, tailored row orientation, staggered heights between rows and the mixing of plant varieties can improve crop yields. While sunlight is generally considered a plentiful resource, the exceptions highlight the importance of solar energy to agriculture. During the short growing seasons of the Little Ice Age, French and English farmers employed fruit walls to maximize the collection of solar energy. These walls acted as thermal masses and accelerated ripening by keeping plants warm. Early fruit walls were built perpendicular to the ground and facing south, but over time, sloping walls were developed to make better use of sunlight. In 1699, Nicolas Fatio de Duillier even suggested using a tracking mechanism which could pivot to follow the Sun. Applications of solar energy in agriculture aside from growing crops include pumping water, drying crops, brooding chicks and drying chicken manure. More recently the technology has been embraced by vinters, who use the energy generated by solar panels to power grape presses.

Answer: timed planting cycles, tailored row orientation, staggered heights between rows and the mixing of plant varieties
Question: Greece attracts more than 16 million tourists each year, thus contributing 18.2% to the nation's GDP in 2008 according to an OECD report. The same survey showed that the average tourist expenditure while in Greece was $1,073, ranking Greece 10th in the world. The number of jobs directly or indirectly related to the tourism sector were 840,000 in 2008 and represented 19% of the country's total labor force. In 2009, Greece welcomed over 19.3 million tourists, a major increase from the 17.7 million tourists the country welcomed in 2008.
Try to answer this question if possible: How many tourists did Greece welcome in 2009?
Answer:
over 19.3 million
