Input: Gene
Essential genes are the set of genes thought to be critical for an organism's survival. This definition assumes the abundant availability of all relevant nutrients and the absence of environmental stress. Only a small portion of an organism's genes are essential. In bacteria, an estimated 250400 genes are essential for Escherichia coli and Bacillus subtilis, which is less than 10% of their genes. Half of these genes are orthologs in both organisms and are largely involved in protein synthesis. In the budding yeast Saccharomyces cerevisiae the number of essential genes is slightly higher, at 1000 genes (~20% of their genes). Although the number is more difficult to measure in higher eukaryotes, mice and humans are estimated to have around 2000 essential genes (~10% of their genes).

What are the set of genes which are thought to be crucial for the survival of an organism?
Output: Essential genes

Input: Insect
The thorax is a tagma composed of three sections, the prothorax, mesothorax and the metathorax. The anterior segment, closest to the head, is the prothorax, with the major features being the first pair of legs and the pronotum. The middle segment is the mesothorax, with the major features being the second pair of legs and the anterior wings. The third and most posterior segment, abutting the abdomen, is the metathorax, which features the third pair of legs and the posterior wings. Each segment is dilineated by an intersegmental suture. Each segment has four basic regions. The dorsal surface is called the tergum (or notum) to distinguish it from the abdominal terga. The two lateral regions are called the pleura (singular: pleuron) and the ventral aspect is called the sternum. In turn, the notum of the prothorax is called the pronotum, the notum for the mesothorax is called the mesonotum and the notum for the metathorax is called the metanotum. Continuing with this logic, the mesopleura and metapleura, as well as the mesosternum and metasternum, are used.

Another term for tagma is?
Output: thorax

Input: Indigenous peoples of the Americas
Over the course of thousands of years, American indigenous peoples domesticated, bred and cultivated a large array of plant species. These species now constitute 5060% of all crops in cultivation worldwide. In certain cases, the indigenous peoples developed entirely new species and strains through artificial selection, as was the case in the domestication and breeding of maize from wild teosinte grasses in the valleys of southern Mexico. Numerous such agricultural products retain their native names in the English and Spanish lexicons.

How were new species and strains of crops developed?
Output: artificial selection

Input: Department store
Chain department stores grew rapidly after 1920, and provided competition for the downtown upscale department stores, as well as local department stores in small cities. J. C. Penney had four stores in 1908, 312 in 1920, and 1452 in 1930. Sears, Roebuck & Company, a giant mail-order house, opened its first eight retail stores in 1925, and operated 338 by 1930, and 595 by 1940. The chains reached a middle-class audience, that was more interested in value than in upscale fashions. Sears was a pioneer in creating department stores that catered to men as well as women, especially with lines of hardware and building materials. It deemphasized the latest fashions in favor of practicality and durability, and allowed customers to select goods without the aid of a clerk. Its stores were oriented to motorists set apart from existing business districts amid residential areas occupied by their target audience; had ample, free, off-street parking; and communicated a clear corporate identity. In the 1930s, the company designed fully air-conditioned, "windowless" stores whose layout was driven wholly by merchandising concerns.

What demographic were most stores focusing on?
Output:
middle-class audience
