Cara Cusumano, director of the Tribeca Film Festival, stated in April 2014: "Piracy is less about people not wanting to pay and more about just wanting the immediacy – people saying, 'I want to watch Spiderman right now' and downloading it". The statement occurred during the third year that the festival used the Internet to present its content, while it was the first year that it featured a showcase of content producers who work exclusively online. Cusumano further explained that downloading behavior is not merely conducted by people who merely want to obtain content for free:

Problem: Molecules are moved within plants by transport processes that operate at a variety of spatial scales. Subcellular transport of ions, electrons and molecules such as water and enzymes occurs across cell membranes. Minerals and water are transported from roots to other parts of the plant in the transpiration stream. Diffusion, osmosis, and active transport and mass flow are all different ways transport can occur. Examples of elements that plants need to transport are nitrogen, phosphorus, potassium, calcium, magnesium, and sulphur. In vascular plants, these elements are extracted from the soil as soluble ions by the roots and transported throughout the plant in the xylem. Most of the elements required for plant nutrition come from the chemical breakdown of soil minerals. Sucrose produced by photosynthesis is transported from the leaves to other parts of the plant in the phloem and plant hormones are transported by a variety of processes.
How is water transported into plants?

Answer: from roots


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
With the extension of Turkish dominion into the Balkans, the strategic conquest of Constantinople became a crucial objective. The empire had managed to control nearly all former Byzantine lands surrounding the city, but in 1402 the Byzantines were temporarily relieved when the Turco-Mongol leader Timur, founder of the Timurid Empire, invaded Anatolia from the east. In the Battle of Ankara in 1402, Timur defeated the Ottoman forces and took Sultan Bayezid I as a prisoner, throwing the empire into disorder. The ensuing civil war lasted from 1402 to 1413 as Bayezid's sons fought over succession. It ended when Mehmed I emerged as the sultan and restored Ottoman power, bringing an end to the Interregnum, also known as the Fetret Devri.
What leader invaded Anatolia from the east?
A: Timur

Question: The Virgin birth of Jesus was an almost universally held belief among Christians from the 2nd until the 19th century. It is included in the two most widely used Christian creeds, which state that Jesus "was incarnate of the Holy Spirit and the Virgin Mary" (the Nicene Creed in what is now its familiar form) and the Apostles' Creed. The Gospel of Matthew describes Mary as a virgin who fulfilled the prophecy of Isaiah 7:14, mistranslating the Hebrew word alma ("young woman") in Isaiah 7:14 as "virgin", though.[citation needed] The authors of the Gospels of Matthew and Luke consider Jesus' conception not the result of intercourse and assert that Mary had "no relations with man" before Jesus' birth.[Mt 1:18] [Mt 1:25] [Lk 1:34] This alludes to the belief that Mary conceived Jesus through the action of God the Holy Spirit, and not through intercourse with Joseph or anyone else.
Is there an answer to this question: Along with the Nicene Creed, which other Christian creed asserts the Virgin birth of Jesus?

Answer: the Apostles' Creed


In Britain and some other armies, the single artillery branch has been responsible for both home and overseas ground-based air defence, although there was divided responsibility with the Royal Navy for air defence of the British Isles in World War I. However, during the Second World War the RAF Regiment was formed to protect airfields everywhere, and this included light air defences. In the later decades of the Cold War this included the United States Air Force's operating bases in UK. However, all ground-based air defence was removed from Royal Air Force (RAF) jurisdiction in 2004. The British Army's Anti-Aircraft Command was disbanded in March 1955, but during the 1960s and 1970s the RAF's Fighter Command operated long-range air -defence missiles to protect key areas in the UK. During World War II the Royal Marines also provided air defence units; formally part of the mobile naval base defence organisation, they were handled as an integral part of the army-commanded ground based air defences.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who provided part of the air defence of the British Isles in WWI
Ah, so..
Royal Navy
