Problem: Please answer a question about the following article about Pharmaceutical industry:
In 1952 researchers at Ciba discovered the first orally available vasodilator, hydralazine. A major shortcoming of hydralazine monotherapy was that it lost its effectiveness over time (tachyphylaxis). In the mid-1950s Karl H. Beyer, James M. Sprague, John E. Baer, and Frederick C. Novello of Merck and Co. discovered and developed chlorothiazide, which remains the most widely used antihypertensive drug today. This development was associated with a substantial decline in the mortality rate among people with hypertension. The inventors were recognized by a Public Health Lasker Award in 1975 for "the saving of untold thousands of lives and the alleviation of the suffering of millions of victims of hypertension".
Who discovered Hydralazine?
A: researchers at Ciba
Problem: Please answer a question about the following article about Modern history:
Society in the Japanese "Tokugawa period" (Edo society), unlike the shogunates before it, was based on the strict class hierarchy originally established by Toyotomi Hideyoshi. The daimyo, or lords, were at the top, followed by the warrior-caste of samurai, with the farmers, artisans, and traders ranking below. In some parts of the country, particularly smaller regions, daimyo and samurai were more or less identical, since daimyo might be trained as samurai, and samurai might act as local lords. Otherwise, the largely inflexible nature of this social stratification system unleashed disruptive forces over time. Taxes on the peasantry were set at fixed amounts which did not account for inflation or other changes in monetary value. As a result, the tax revenues collected by the samurai landowners were worth less and less over time. This often led to numerous confrontations between noble but impoverished samurai and well-to-do peasants, ranging from simple local disturbances to much bigger rebellions. None, however, proved compelling enough to seriously challenge the established order until the arrival of foreign powers.
What was society in the Tokugawa period based in?
A: strict class hierarchy
Problem: Please answer a question about the following article about Post-punk:
The term "post-punk" was first used by journalists in the late 1970s to describe groups moving beyond punk's sonic template into disparate areas. Many of these artists, initially inspired by punk's DIY ethic and energy, ultimately became disillusioned with the style and movement, feeling that it had fallen into commercial formula, rock convention and self-parody. They repudiated its populist claims to accessibility and raw simplicity, instead seeing an opportunity to break with musical tradition, subvert commonplaces and challenge audiences. Artists moved beyonds punk's focus on the concerns of a largely white, male, working class population and abandoned its continued reliance on established rock and roll tropes, such as three-chord progressions and Chuck Berry-based guitar riffs. These artists instead defined punk as "an imperative to constant change", believing that "radical content demands radical form".
What did post-punk artists feel there was an imperative to constantly do?
A: change
Problem: Please answer a question about the following article about Flowering plant:
The internal classification of this group has undergone considerable revision. The Cronquist system, proposed by Arthur Cronquist in 1968 and published in its full form in 1981, is still widely used but is no longer believed to accurately reflect phylogeny. A consensus about how the flowering plants should be arranged has recently begun to emerge through the work of the Angiosperm Phylogeny Group (APG), which published an influential reclassification of the angiosperms in 1998. Updates incorporating more recent research were published as APG II in 2003 and as APG III in 2009.
What internal component has undergone considerable revision?
A:
classification
