Problem: Napoleon:

After the setback at Aspern-Essling, Napoleon took more than six weeks in planning and preparing for contingencies before he made another attempt at crossing the Danube. From 30 June to the early days of July, the French recrossed the Danube in strength, with more than 180,000 troops marching across the Marchfeld towards the Austrians. Charles received the French with 150,000 of his own men. In the ensuing Battle of Wagram, which also lasted two days, Napoleon commanded his forces in what was the largest battle of his career up until then. Neither side made much progress on 5 July, but the 6th produced a definitive outcome. Both sides launched major assaults on their flanks. Austrian attacks against the French left wing looked dangerous initially, but they were all beaten back. Meanwhile, a steady French attack against the Austrian left wing eventually compromised the entire position for Charles. Napoleon finished off the battle with a concentrated central thrust that punctured a hole in the Austrian army and forced Charles to retreat. Austrian losses were very heavy, reaching well over 40,000 casualties. The French were too exhausted to pursue the Austrians immediately, but Napoleon eventually caught up with Charles at Znaim and the latter signed an armistice on 12 July.

Approximately how long did Napoleon take to prepare another Danube crossing after his defeat at Aspern-Essling?

A: six weeks

Problem: Some organisms have multiple copies of chromosomes: diploid, triploid, tetraploid and so on. In classical genetics, in a sexually reproducing organism (typically eukarya) the gamete has half the number of chromosomes of the somatic cell and the genome is a full set of chromosomes in a diploid cell. The halving of the genetic material in gametes is accomplished by the segregation of homologous chromosomes during meiosis. In haploid organisms, including cells of bacteria, archaea, and in organelles including mitochondria and chloroplasts, or viruses, that similarly contain genes, the single or set of circular or linear chains of DNA (or RNA for some viruses), likewise constitute the genome. The term genome can be applied specifically to mean what is stored on a complete set of nuclear DNA (i.e., the "nuclear genome") but can also be applied to what is stored within organelles that contain their own DNA, as with the "mitochondrial genome" or the "chloroplast genome". Additionally, the genome can comprise non-chromosomal genetic elements such as viruses, plasmids, and transposable elements.
What are examples of terms used to describe a virus type?

Windows 8 provides heavier integration with online services from Microsoft and others. A user can now log in to Windows with a Microsoft account, which can be used to access services and synchronize applications and settings between devices. Windows 8 also ships with a client app for Microsoft's SkyDrive cloud storage service, which also allows apps to save files directly to SkyDrive. A SkyDrive client for the desktop and File Explorer is not included in Windows 8, and must be downloaded separately. Bundled multimedia apps are provided under the Xbox brand, including Xbox Music, Xbox Video, and the Xbox SmartGlass companion for use with an Xbox 360 console. Games can integrate into an Xbox Live hub app, which also allows users to view their profile and gamerscore. Other bundled apps provide the ability to link Flickr and Facebook. Due to Facebook Connect service changes, Facebook support is disabled in all bundled apps effective June 8, 2015.
What features doesn't Xbox Live hub offer?
A: unanswerable

Context and question: The most widely used symbol is the flag of Greece, which features nine equal horizontal stripes of blue alternating with white representing the nine syllables of the Greek national motto Eleftheria i thanatos (freedom or death), which was the motto of the Greek War of Independence. The blue square in the upper hoist-side corner bears a white cross, which represents Greek Orthodoxy. The Greek flag is widely used by the Greek Cypriots, although Cyprus has officially adopted a neutral flag to ease ethnic tensions with the Turkish Cypriot minority see flag of Cyprus).
What are the representations of the Greek reference freedom or death that are held on a cloth symbol of the nation ?
Answer: flag of Greece, which features nine equal horizontal stripes of blue alternating with white

Question: Actor Dominic West has been unenthusiastic about the career benefits of being an Old Etonian, saying it "is a stigma that is slightly above 'paedophile' in the media in a gallery of infamy", but asked whether he would consider sending his own children there, said "Yes, I would. It's an extraordinary place... It has the facilities and the excellence of teaching and it will find what you're good at and nurture it", while the actor Tom Hiddleston says there are widespread misconceptions about Eton, and that "People think it's just full of braying toffs... It isn't true... It's actually one of the most broadminded places I've ever been. The reason it's a good school is that it encourages people to find the thing they love and to go for it. They champion the talent of the individual and that's what's special about it".
Is there an answer to this question: Who was one of Tom Hiddleston's classmates at Eton?

When a molten metal is mixed with another substance, there are two mechanisms that can cause an alloy to form, called atom exchange and the interstitial mechanism. The relative size of each element in the mix plays a primary role in determining which mechanism will occur. When the atoms are relatively similar in size, the atom exchange method usually happens, where some of the atoms composing the metallic crystals are substituted with atoms of the other constituent. This is called a substitutional alloy. Examples of substitutional alloys include bronze and brass, in which some of the copper atoms are substituted with either tin or zinc atoms. With the interstitial mechanism, one atom is usually much smaller than the other, so cannot successfully replace an atom in the crystals of the base metal. The smaller atoms become trapped in the spaces between the atoms in the crystal matrix, called the interstices. This is referred to as an interstitial alloy. Steel is an example of an interstitial alloy, because the very small carbon atoms fit into interstices of the iron matrix. Stainless steel is an example of a combination of interstitial and substitutional alloys, because the carbon atoms fit into the interstices, but some of the iron atoms are replaced with nickel and chromium atoms.
Tin or zinc atoms in place of copper atoms create?
A:
substitutional alloys
