Here is a question about this article: Palmerston died in 1865, and after a brief ministry led by Russell, Derby returned to power. In 1866, Victoria attended the State Opening of Parliament for the first time since Albert's death. The following year she supported the passing of the Reform Act 1867 which doubled the electorate by extending the franchise to many urban working men, though she was not in favour of votes for women. Derby resigned in 1868, to be replaced by Benjamin Disraeli, who charmed Victoria. "Everyone likes flattery," he said, "and when you come to royalty you should lay it on with a trowel." With the phrase "we authors, Ma'am", he complimented her. Disraeli's ministry only lasted a matter of months, and at the end of the year his Liberal rival, William Ewart Gladstone, was appointed prime minister. Victoria found Gladstone's demeanour far less appealing; he spoke to her, she is thought to have complained, as though she were "a public meeting rather than a woman".
What is the answer to this question: How long was Disraeli in office?
****
So... matter of months

Here is a question about this article: In Denmark you find three department store chains: Magasin (1868), Illum (1891), Salling (1906). Magasin is by far the largest with 6 stores all over the country, with the flagship store being Magasin du Nord on Kongens Nytorv in Copenhagen. Illums only store on Amagertorv in Copenhagen has the appearance of a department store with 20% run by Magasin, but has individual shop owners making it a shopping centre. But in people's mind it remains a department store. Salling has two stores in Jutland with one of these being the reason for the closure of a magasin store due to the competition.
What is the answer to this question: Currently, what is the largest department store chain in Denmark?
****
So... Magasin

Here is a question about this article: The currentvoltage characteristic of an LED is similar to other diodes, in that the current is dependent exponentially on the voltage (see Shockley diode equation). This means that a small change in voltage can cause a large change in current. If the applied voltage exceeds the LED's forward voltage drop by a small amount, the current rating may be exceeded by a large amount, potentially damaging or destroying the LED. The typical solution is to use constant-current power supplies to keep the current below the LED's maximum current rating. Since most common power sources (batteries, mains) are constant-voltage sources, most LED fixtures must include a power converter, at least a current-limiting resistor. However, the high resistance of three-volt coin cells combined with the high differential resistance of nitride-based LEDs makes it possible to power such an LED from such a coin cell without an external resistor.
What is the answer to this question: What is a constant-voltage source?

So...
