Problem: In the Roman era, copper was principally mined on Cyprus, the origin of the name of the metal from aes сyprium (metal of Cyprus), later corrupted to сuprum, from which the words copper (English), cuivre (French), Koper (Dutch) and Kupfer (German) are all derived. Its compounds are commonly encountered as copper(II) salts, which often impart blue or green colors to minerals such as azurite, malachite and turquoise and have been widely used historically as pigments. Architectural structures built with copper corrode to give green verdigris (or patina). Decorative art prominently features copper, both by itself and in the form of pigments.
What componds are common in copper?
The answer is the following: copper(II) salts

Problem: Underpinning Houston's land surface are unconsolidated clays, clay shales, and poorly cemented sands up to several miles deep. The region's geology developed from river deposits formed from the erosion of the Rocky Mountains. These sediments consist of a series of sands and clays deposited on decaying organic marine matter, that over time, transformed into oil and natural gas. Beneath the layers of sediment is a water-deposited layer of halite, a rock salt. The porous layers were compressed over time and forced upward. As it pushed upward, the salt dragged surrounding sediments into salt dome formations, often trapping oil and gas that seeped from the surrounding porous sands. The thick, rich, sometimes black, surface soil is suitable for rice farming in suburban outskirts where the city continues to grow.
What type of farming is Houston's surface soil good for?
The answer is the following: rice farming

Problem: The Ecdysozoa are protostomes, named after the common trait of growth by moulting or ecdysis. The largest animal phylum belongs here, the Arthropoda, including insects, spiders, crabs, and their kin. All these organisms have a body divided into repeating segments, typically with paired appendages. Two smaller phyla, the Onychophora and Tardigrada, are close relatives of the arthropods and share these traits. The ecdysozoans also include the Nematoda or roundworms, perhaps the second largest animal phylum. Roundworms are typically microscopic, and occur in nearly every environment where there is water. A number are important parasites. Smaller phyla related to them are the Nematomorpha or horsehair worms, and the Kinorhyncha, Priapulida, and Loricifera. These groups have a reduced coelom, called a pseudocoelom.
What is another name for roundworms?
The answer is the following: Nematoda

Problem: The term Cubism did not come into general usage until 1911, mainly with reference to Metzinger, Gleizes, Delaunay, and Léger. In 1911, the poet and critic Guillaume Apollinaire accepted the term on behalf of a group of artists invited to exhibit at the Brussels Indépendants. The following year, in preparation for the Salon de la Section d'Or, Metzinger and Gleizes wrote and published Du "Cubisme" in an effort to dispel the confusion raging around the word, and as a major defence of Cubism (which had caused a public scandal following the 1911 Salon des Indépendants and the 1912 Salon d'Automne in Paris). Clarifying their aims as artists, this work was the first theoretical treatise on Cubism and it still remains the clearest and most intelligible. The result, not solely a collaboration between its two authors, reflected discussions by the circle of artists who met in Puteaux and Courbevoie. It mirrored the attitudes of the "artists of Passy", which included Picabia and the Duchamp brothers, to whom sections of it were read prior to publication. The concept developed in Du "Cubisme" of observing a subject from different points in space and time simultaneously, i.e., the act of moving around an object to seize it from several successive angles fused into a single image (multiple viewpoints, mobile perspective, simultaneity or multiplicity), is a generally recognized device used by the Cubists.
What year did the term Cubism become used more?
The answer is the following:
1911
