Offensive Counterair (OCA) is defined as "offensive operations to destroy, disrupt, or neutralize enemy aircraft, missiles, launch platforms, and their supporting structures and systems both before and after launch, but as close to their source as possible" (JP 1-02). OCA is the preferred method of countering air and missile threats, since it attempts to defeat the enemy closer to its source and typically enjoys the initiative. OCA comprises attack operations, sweep, escort, and suppression/destruction of enemy air defense.
What is one of the important functions of the OCA in dealing with attacks?
suppression/destruction of enemy air defense

Input: Dell
The release of Apple's iPad tablet computer had a negative impact on Dell and other major PC vendors, as consumers switched away from desktop and laptop PCs. Dell's own mobility division has not managed success with developing smartphones or tablets, whether running Windows or Google Android. The Dell Streak was a failure commercially and critically due to its outdated OS, numerous bugs, and low resolution screen. InfoWorld suggested that Dell and other OEMs saw tablets as a short-term, low-investment opportunity running Google Android, an approach that neglected user interface and failed to gain long term market traction with consumers. Dell has responded by pushing higher-end PCs, such as the XPS line of notebooks, which do not compete with the Apple iPad and Kindle Fire tablets. The growing popularity of smartphones and tablet computers instead of PCs drove Dell's consumer segment to an operating loss in Q3 2012. In December 2012, Dell suffered its first decline in holiday sales in five years, despite the introduction of Windows 8.

What line of high end electronics did Dell create that failed to compete with Apple products?
Output: XPS

Input: Article: These symmetries are represented by functions. Each of these functions sends a point in the square to the corresponding point under the symmetry. For example, r1 sends a point to its rotation 90 clockwise around the square's center, and fh sends a point to its reflection across the square's vertical middle line. Composing two of these symmetry functions gives another symmetry function. These symmetries determine a group called the dihedral group of degree 4 and denoted D4. The underlying set of the group is the above set of symmetry functions, and the group operation is function composition. Two symmetries are combined by composing them as functions, that is, applying the first one to the square, and the second one to the result of the first application. The result of performing first a and then b is written symbolically from right to left as

Now answer this question: What sends a point in the square to the relating point under the symmetry?

Output: functions

Article: At the end of the 16th century, England and the Netherlands began to challenge Portugal's monopoly of trade with Asia, forming private joint-stock companies to finance the voyagesthe English, later British, East India Company and the Dutch East India Company, chartered in 1600 and 1602 respectively. The primary aim of these companies was to tap into the lucrative spice trade, an effort focused mainly on two regions; the East Indies archipelago, and an important hub in the trade network, India. There, they competed for trade supremacy with Portugal and with each other. Although England ultimately eclipsed the Netherlands as a colonial power, in the short term the Netherlands' more advanced financial system and the three Anglo-Dutch Wars of the 17th century left it with a stronger position in Asia. Hostilities ceased after the Glorious Revolution of 1688 when the Dutch William of Orange ascended the English throne, bringing peace between the Netherlands and England. A deal between the two nations left the spice trade of the East Indies archipelago to the Netherlands and the textiles industry of India to England, but textiles soon overtook spices in terms of profitability, and by 1720, in terms of sales, the British company had overtaken the Dutch.

Question: How many Anglo-Dutch Wars were there in the 17th century?
Ans: three

Here is a question about this article: In 1903 Hermann Emil Fischer and Joseph von Mering disclosed their discovery that diethylbarbituric acid, formed from the reaction of diethylmalonic acid, phosphorus oxychloride and urea, induces sleep in dogs. The discovery was patented and licensed to Bayer pharmaceuticals, which marketed the compound under the trade name Veronal as a sleep aid beginning in 1904. Systematic investigations of the effect of structural changes on potency and duration of action led to the discovery of phenobarbital at Bayer in 1911 and the discovery of its potent anti-epileptic activity in 1912. Phenobarbital was among the most widely used drugs for the treatment of epilepsy through the 1970s, and as of 2014, remains on the World Health Organizations list of essential medications. The 1950s and 1960s saw increased awareness of the addictive properties and abuse potential of barbiturates and amphetamines and led to increasing restrictions on their use and growing government oversight of prescribers. Today, amphetamine is largely restricted to use in the treatment of attention deficit disorder and phenobarbital in the treatment of epilepsy.
What is the answer to this question: Who discovered a reaction that induced sleep in dogs?
****
So... Hermann Emil Fischer and Joseph von Mering

Article: Following the defeat of the German empire in World War I and the abdication of the German Emperor, some revolutionary insurgents declared Alsace-Lorraine as an independent Republic, without preliminary referendum or vote. On 11 November 1918 (Armistice Day), communist insurgents proclaimed a "soviet government" in Strasbourg, following the example of Kurt Eisner in Munich as well as other German towns. French troops commanded by French general Henri Gouraud entered triumphantly in the city on 22 November. A major street of the city now bears the name of that date (Rue du 22 Novembre) which celebrates the entry of the French in the city. Viewing the massive cheering crowd gathered under the balcony of Strasbourg's town hall, French President Raymond Poincare stated that "the plebiscite is done".

Question: Who commanded the French troops on November 22?
Ans:
French general Henri Gouraud
