Cardigan formed up his unit and charged the length of the Valley of the Balaclava, under fire from Russian batteries in the hills. The charge of the Light Brigade caused 278 casualties of the 700-man unit. The Light Brigade was memorialized in the famous poem by Alfred Lord Tennyson, "The Charge of the Light Brigade." Although traditionally the charge of the Light Brigade was looked upon as a glorious but wasted sacrifice of good men and horses, recent historians say that the charge of the Light Brigade did succeed in at least some of its objectives. The aim of any cavalry charge is to scatter the enemy lines and frighten the enemy off the battlefield. The charge of the Light Brigade had so unnerved the Russian cavalry, which had previously been routed by the Heavy Brigade, that the Russian Cavalry was set to full-scale flight by the subsequent charge of the Light Brigade.:252

Who led the charge on the Valley of Balaclava?
Answer: Cardigan

Problem: About that time the "executionist movement" (Polish: "egzekucja praw"--"execution of the laws") began to take form. Its members would seek to curb the power of the magnates at the Sejm and to strengthen the power of king and country. In 1562 at the Sejm in Piotrkow they would force the magnates to return many leased crown lands to the king, and the king to create a standing army (wojsko kwarciane). One of the most famous members of this movement was Jan Zamoyski. After his death in 1605, the movement lost its political force.
WHen did Jan Zamoyski. die?
The answer is the following: 1605

Passenger elevators capacity is related to the available floor space. Generally passenger elevators are available in capacities from 500 to 2,700 kg (1,0006,000 lb) in 230 kg (500 lb) increments.[citation needed] Generally passenger elevators in buildings of eight floors or fewer are hydraulic or electric, which can reach speeds up to 1 m/s (200 ft/min) hydraulic and up to 152 m/min (500 ft/min) electric. In buildings up to ten floors, electric and gearless elevators are likely to have speeds up to 3 m/s (500 ft/min), and above ten floors speeds range 3 to 10 m/s (5002,000 ft/min).[citation needed]
What types of passenger elevators are installed in structures of up to eight floors?
hydraulic or electric

Input: Lighting
An important property of light fixtures is the luminous efficacy or wall-plug efficiency, meaning the amount of usable light emanating from the fixture per used energy, usually measured in lumen per watt. A fixture using replaceable light sources can also have its efficiency quoted as the percentage of light passed from the "bulb" to the surroundings. The more transparent the lighting fixture is, the higher efficacy. Shading the light will normally decrease efficacy but increase the directionality and the visual comfort probability.

Luminous efficacy is measure in what unit?
Output: lumen per watt

Input: Article: In some countries, such as Britain and Germany during the Second World War, the Soviet Union and NATO's Allied Command Europe, ground based air defence and air defence aircraft have been under integrated command and control. However, while overall air defence may be for homeland defence including military facilities, forces in the field, wherever they are, invariably deploy their own air defence capability if there is an air threat. A surface-based air defence capability can also be deployed offensively to deny the use of airspace to an opponent.

Now answer this question: What can be deployed as an offensive measure to refuse airspace use to an opponent?

Output: A surface-based air defence capability

Problem: Administratively, Portugal is divided into 308 municipalities (Portuguese: municipios or concelhos), which after a reform in 2013 are subdivided into 3,092 civil parishes (Portuguese: freguesia). Operationally, the municipality and civil parish, along with the national government, are the only legally identifiable local administrative units identified by the government of Portugal (for example, cities, towns or villages have no standing in law, although may be used as catchment for the defining services). For statistical purposes the Portuguese government also identifies NUTS, inter-municipal communities and informally, the district system, used until European integration (and being phased-out by the national government).[original research?] Continental Portugal is agglomerated into 18 districts, while the archipelagos of the Azores and Madeira are governed as autonomous regions; the largest units, established since 1976, are either mainland Portugal (Portuguese: Portugal Continental) and the autonomous regions of Portugal (Azores and Madeira).
How many districts is the continental Portugal divided into?
The answer is the following:
18
