The problem: Answer a question about this article:
Birds sometimes use plumage to assess and assert social dominance, to display breeding condition in sexually selected species, or to make threatening displays, as in the sunbittern's mimicry of a large predator to ward off hawks and protect young chicks. Variation in plumage also allows for the identification of birds, particularly between species. Visual communication among birds may also involve ritualised displays, which have developed from non-signalling actions such as preening, the adjustments of feather position, pecking, or other behaviour. These displays may signal aggression or submission or may contribute to the formation of pair-bonds. The most elaborate displays occur during courtship, where "dances" are often formed from complex combinations of many possible component movements; males' breeding success may depend on the quality of such displays.
Visual communication among birds may involve what kind of displays?
****
The answer: ritualised displays


Problem: Please answer a question about the following article about Brain:
The invention of electronic computers in the 1940s, along with the development of mathematical information theory, led to a realization that brains can potentially be understood as information processing systems. This concept formed the basis of the field of cybernetics, and eventually gave rise to the field now known as computational neuroscience. The earliest attempts at cybernetics were somewhat crude in that they treated the brain as essentially a digital computer in disguise, as for example in John von Neumann's 1958 book, The Computer and the Brain. Over the years, though, accumulating information about the electrical responses of brain cells recorded from behaving animals has steadily moved theoretical concepts in the direction of increasing realism.
Computers were invented in what decade in history?
A: 1940s

From the 8th to the 10th century, three dynasties contested for control of northern India: the Gurjara Pratiharas of Malwa, the Palas of Bengal, and the Rashtrakutas of the Deccan. The Sena dynasty would later assume control of the Pala Empire, and the Gurjara Pratiharas fragmented into various states. These were the first of the Rajput states. The first recorded Rajput kingdoms emerged in Rajasthan in the 6th century, and small Rajput dynasties later ruled much of northern India. One Gurjar Rajput of the Chauhan clan, Prithvi Raj Chauhan, was known for bloody conflicts against the advancing Turkic sultanates. The Chola empire emerged as a major power during the reign of Raja Raja Chola I and Rajendra Chola I who successfully invaded parts of Southeast Asia and Sri Lanka in the 11th century. Lalitaditya Muktapida (r. 724 CE–760 CE) was an emperor of the Kashmiri Karkoṭa dynasty, which exercised influence in northwestern India from 625 CE until 1003, and was followed by Lohara dynasty. He is known primarily for his successful battles against the Muslim and Tibetan advances into Kashmiri-dominated regions. Kalhana in his Rajatarangini credits king Lalitaditya with leading an aggressive military campaign in Northern India and Central Asia. He broke into the Uttarapatha and defeated the rebellious tribes of the Kambojas, Tukharas (Turks in Turkmenistan and Tocharians in Badakhshan), Bhautas (Tibetans in Baltistan and Tibet) and Daradas (Dards). His campaign then led him to subjugate the kingdoms of Pragjyotisha, Strirajya and the Uttarakurus. The Shahi dynasty ruled portions of eastern Afghanistan, northern Pakistan, and Kashmir from the mid-7th century to the early 11th century.

When did the first Rajput kingdoms emerge in India?
Answer: 6th century


Problem: Most laboratory techniques for growing bacteria use high levels of nutrients to produce large amounts of cells cheaply and quickly. However, in natural environments, nutrients are limited, meaning that bacteria cannot continue to reproduce indefinitely. This nutrient limitation has led the evolution of different growth strategies (see r/K selection theory). Some organisms can grow extremely rapidly when nutrients become available, such as the formation of algal (and cyanobacterial) blooms that often occur in lakes during the summer. Other organisms have adaptations to harsh environments, such as the production of multiple antibiotics by Streptomyces that inhibit the growth of competing microorganisms. In nature, many organisms live in communities (e.g., biofilms) that may allow for increased supply of nutrients and protection from environmental stresses. These relationships can be essential for growth of a particular organism or group of organisms (syntrophy).
What is the simple way of producing large volume of bacteria cells?
The answer is the following: high levels of nutrients


American Idol has traditionally released studio recordings of contestants' performances as well as the winner's coronation single for sale. For the first five seasons, the recordings were released as a compilation album at the end of the season. All five of these albums reached the top ten in Billboard 200 which made then American Idol the most successful soundtrack franchise of any motion picture or television program. Starting late in season five, individual performances were released during the season as digital downloads, initially from the American Idol official website only. In season seven the live performances and studio recordings were made available during the season from iTunes when it joined as a sponsor. In Season ten the weekly studio recordings were also released as compilation digital album straight after performance night.
How were the recordings released for the initial five seasons?
as a compilation album
