Among the reasons this speech was so greatly admired was its passage on Lord Bathurst (16841775); Burke describes an angel in 1704 prophesying to Bathurst the future greatness of England and also of America: "Young man, There is America which at this day serves little more than to amuse you with stories of savage men, and uncouth manners; yet shall, before you taste of death, shew itself equal to the whole of that commerce which now attracts the envy of the world". Samuel Johnson was so irritated at hearing it continually praised, that he made a parody of it, where the devil appears to a young Whig and predicts that in short time, Whiggism will poison even the paradise of America!
When did an angel supposedly speak to Bathurst?
****
The answer: 1704

These areas contain some spectacular scenery as well, as evidenced by such national parks as Yosemite and Mount Rainier. West of the Cascades and Sierra Nevada is a series of valleys, such as the Central Valley in California and the Willamette Valley in Oregon. Along the coast is a series of low mountain ranges known as the Pacific Coast Ranges. Much of the Pacific Northwest coast is inhabited by some of the densest vegetation outside of the Tropics, and also the tallest trees in the world (the Redwoods).
What are two national parks located in the mountainous regions?
****
The answer: Yosemite and Mount Rainier

The problem: Answer a question about this article:
Instead, it is often desired to have an antenna whose impedance does not vary so greatly over a certain bandwidth. It turns out that the amount of reactance seen at the terminals of a resonant antenna when the frequency is shifted, say, by 5%, depends very much on the diameter of the conductor used. A long thin wire used as a half-wave dipole (or quarter wave monopole) will have a reactance significantly greater than the resistive impedance it has at resonance, leading to a poor match and generally unacceptable performance. Making the element using a tube of a diameter perhaps 1/50 of its length, however, results in a reactance at this altered frequency which is not so great, and a much less serious mismatch which will only modestly damage the antenna's net performance. Thus rather thick tubes are typically used for the solid elements of such antennas, including Yagi-Uda arrays.
What characteristic of the conductor changes the amount of reactance?
****
The answer: diameter

On the Origin of Species, published on 24 November 1859, is a work of scientific literature by Charles Darwin which is considered to be the foundation of evolutionary biology. Darwin's book introduced the scientific theory that populations evolve over the course of generations through a process of natural selection. It presented a body of evidence that the diversity of life arose by common descent through a branching pattern of evolution. Darwin included evidence that he had gathered on the Beagle expedition in the 1830s and his subsequent findings from research, correspondence, and experimentation.
When was the Origin of Species published?

The answer:
24 November 1859
