Article: Phytochemistry is a branch of plant biochemistry primarily concerned with the chemical substances produced by plants during secondary metabolism. Some of these compounds are toxins such as the alkaloid coniine from hemlock. Others, such as the essential oils peppermint oil and lemon oil are useful for their aroma, as flavourings and spices (e.g., capsaicin), and in medicine as pharmaceuticals as in opium from opium poppies. Many medicinal and recreational drugs, such as tetrahydrocannabinol (active ingredient in cannabis), caffeine, morphine and nicotine come directly from plants. Others are simple derivatives of botanical natural products. For example, the pain killer aspirin is the acetyl ester of salicylic acid, originally isolated from the bark of willow trees, and a wide range of opiate painkillers like heroin are obtained by chemical modification of morphine obtained from the opium poppy. Popular stimulants come from plants, such as caffeine from coffee, tea and chocolate, and nicotine from tobacco. Most alcoholic beverages come from fermentation of carbohydrate-rich plant products such as barley (beer), rice (sake) and grapes (wine).

Question: What is the study of the chemicals that plants produce?
Ans: Phytochemistry

Here is a question about this article: The architecture and urbanism of the Classical civilizations such as the Greek and the Roman evolved from civic ideals rather than religious or empirical ones and new building types emerged. Architectural "style" developed in the form of the Classical orders.
What is the answer to this question: What owes its development to the Classical orders?
****
So... Architectural "style"

The problem: Answer a question about this article:
Several animal phyla are recognized for their lack of bilateral symmetry, and are thought to have diverged from other animals early in evolution. Among these, the sponges (Porifera) were long thought to have diverged first, representing the oldest animal phylum. They lack the complex organization found in most other phyla. Their cells are differentiated, but in most cases not organized into distinct tissues. Sponges typically feed by drawing in water through pores. However, a series of phylogenomic studies from 2008-2015 have found support for Ctenophora, or comb jellies, as the basal lineage of animals. This result has been controversial, since it would imply that that sponges may not be so primitive, but may instead be secondarily simplified. Other researchers have argued that the placement of Ctenophora as the earliest-diverging animal phylum is a statistical anomaly caused by the high rate of evolution in ctenophore genomes.
During what time were a series of phylogenomic studies conducted that found support for comb jellies as the basal lineage of animals?
****
The answer: 2008-2015

Problem: Please answer a question about the following article about Age of Enlightenment:
The Enlightenment known in French as the Siecle des Lumieres, the Century of Enlightenment, and in German as the Aufklarung was a philosophical movement which dominated the world of ideas in Europe in the 18th century. The Enlightenment included a range of ideas centered on reason as the primary source of authority and legitimacy, and came to advance ideals such as liberty, progress, tolerance, fraternity, constitutional government and ending the abuses of the church and state. In France, the central doctrines of the Lumieres were individual liberty and religious tolerance, in opposition to the principle of absolute monarchy and the fixed dogmas of the Roman Catholic Church. The Enlightenment was marked by increasing empiricism, scientific rigor, and reductionism, along with increased questioning of religious orthodoxy.
In France, what were the central doctrines of the Lumieres?
A: individual liberty and religious tolerance

The Assembly consisted of nine seats, with electors casting nine equal votes, of which no more than two could be given to any individual candidate. It is a method of voting called a "weighted first past the post system". Four of the members of the Assembly formed the Executive Council, which devised policy and acted as an advisory body to the Administrator. The last Chief Minister of Norfolk Island was Lisle Snell. Other ministers included: Minister for Tourism, Industry and Development; Minister for Finance; Minister for Cultural Heritage and Community Services; and Minister for Environment.

What method of voting does Norfolk Island use for it's Assembly?
Answer: a "weighted first past the post system"
